Set released on DD MMMM YYYY

• Super Mario Galaxy – Guide and Walkthrough

Super Mario Galaxy is quite linear. In all but one case are you able to retry a level and keep going. However, there is one single missable achievement right at the beginning of the game. Outside of this, there are no other missables.

This game has 5 real "states." There were many ways of designing this guide, so I went with Dome > Galaxy > Achievements. This guide is not really designed to be followed in order, since you can do a lot of the game in your own way.

Here are the five states:

• Mario, pre-Any% (the game until you beat Bowser in the Center of the Universe for the first time)
• Mario, pre-100% (the game until you get all 120 stars and beat Bowser again)
• Luigi, pre-Any% (the game until you beat Bowser as Luigi in the Center of the Universe)
• Luigi, pre-100% (the game until you get all 120 stars as Luigi and beat Bowser again)
• Everything else (Stars 241 and 242)

A lot of achievements require you getting 100% as each character. These will be noted as such under each achievement. Challenges can be done at any time. However, I usually recommend beating 100% first (excluding the missable, unless you want to come back) to get experience with the game as some challenges are quite difficult, even for experienced players.

Note that all the achievements for beating each galaxy only require you to beat every non-Purple coin mission. This is equivalent to seeing the "Silver" crown, instead of the "Gold" one that you get when you get that one as well. As a result, this guide will be completely disregarding these missions unless they have an achievement. You will see "this galaxy has 5 missions" even though there is a sixth, it's not relevant for any achievement (other than 120 stars, I suppose).

Finally, it's highly recommended to do most of the challenge achievements as Luigi. He runs faster, jumps higher and farther, and gives you a bit more edge in the timed achievements. Unless otherwise mentioned, you should use him. However, everything is still possible as Mario if you want a harder challenge.

These achievements happen in the prologue. Note that you can come back here later in the game, after you finish the Engine room. This is the only category with a missable achievement (one).

Title	Guidance & Insights
Olly Olly Oxen-Done	Catch all three rabbits in hide-and-seek on Gateway Galaxy's starting planet in less than 1 minute. MISSABLE. This is the only missable achievement in the set. And, it's at the very start! There are 3 bunnies, one in the pit (not the one that goes all the way through), one in the grass bushes a bit to the left after you first talk to the bunnies, and one in the pipe. The bunnies get tired quite quickly. When you start, go left and over the white rocks and fall in the pit. Beyond that is the pipe, and beyond the pipe is the grass with the bunnies. Feel free to spawn them all then capture them, whatever you want. Time stops whenever you capture the last bunny. If you take more than one minute, you can quit the game from the pause menu and re-enter, skipping all the cutscenes. Achievement Tracking - A Trigger Indicator shows up after you first talk to the bunnies
Twisting the Night Away	Learn how to spin as Mario. Progression. Can't be missed. You will get this after you first talk to "mama".
The Yellow Brick Road	Complete the flip switch puzzle in Gateway Galaxy without changing any yellow flip switches back to blue. Challenge: In the final pipe, where the grand star is hidden, there are a bunch of yellow switches. Walking over them will switch them to blue, and they will stay blue until you walk off and back on. There are 4 under the rotating platforms that you'll get walking around, and another 12 a square surrounding the Grand Star. There is a Goomba you can knock away with a star bit if you are worried it will be in your way, then kick it while it is spinning (or ignore it if it's far enough out of the way). Then, walk around and turn those panels blue! Don't worry about forgetting or messing this up, you can come back to this mission later in the game. Fail Conditions - Turning any switches from blue to yellow
Gateway to Observation	Complete the Grand Star Rescue and earn your first star. Progression, can't be missed.

🔗 Back to Top of Achievement Category

The Comet Observatory has several states throughout the game. The major ones are every time you get a Grand Star; however, the Observatory does naturally evolve in some other aspects. Some achievements help track these!

Title	Guidance & Insights
Shiitake Starfarers	Meet the Toad Brigade and have them set up shop at the Cosmic Observatory. Progression: You will get this after beating Bee Mario Takes Flight in the Honeyhive Galaxy.
Interstellar Fungi	Recover enough Power Stars for the Lumas to complete the Starshroom. Progression: You will get this as you progress through the game.
Sweet Ride	Reach Sweet Sweet Galaxy without using a launch star. Challenge: This requires unlocking the Red Star, which you can do after unlocking the Garden (and thus, the Gateway Galaxy). Grab the Red Star and simply fly up and into the Galaxy that the launch star would typically take you to.
He Was an Electrician in Another Life	Restore full power to the observatory as Mario. Progression, can't be missed. Happens when you get the Grand Star in the Bedroom.
Full Throttle	Restore full power to the observatory as Luigi. Progression (towards beating the game as Luigi), can't be missed. Happens when you get the Grand Star in the Bedroom.
Fungal Five	Collect all five 1-up mushrooms on the Comet Observatory while only one flying power up is active. Challenge: There are five 1-up mushrooms throughout the Comet Observatory. Collect them all while and only using one Red Star power-up. Note that not all 1-ups appear at first. But, by the time you get the Red Star (after the bedroom Grand Star), they should all be there. This is my recommended order: The first 1-up is in the Garage, in a box, and is always accessible. The second 1-up is under the Bedroom that you can get to by riding the green platform. Unlocks after getting the Fountain Grand Star. The third 1-up is under the stairs up to the Kitchen (go right instead of left up the steps). Unlocks after getting the Fountain Grand Star. The fourth 1-up is under the Gateway Galaxy island. Unlocks after getting the Bedroom Grand Star. The fifth and final 1-up is on top of the spire at the very top of the Observatory. Unlocks after getting the Bedroom Grand Star. As for the path. First, get the first 1-up in the box. Do a fly u-turn around the Starshroom and fly right into the 2nd 1-up under the Bedroom. Then keep flying and go up quickly because the Kitchen and 3rd 1-up is right there. Then, turn around and fly up to the 4th 1-up under the Gateway Island. Finally, head to the top of the observatory and grab the final 1-up. Fail Conditions - Collecting a 1-up without using the red star - Collecting another red star - Running out of a red star Achievement Tracking - A Trigger Indicator will appear when you first collect the red star - A Measured Indicator will increment each 1-up collected
A Novel Constellation	Unlock Rosalina's library. Progression, can't be missed. The library unlocks partway through the game. You'll get this when it unlocks, and it tells you when you do.
Mother of the Stars	Complete storytime with Rosalina. Challenge? This is optional, but fun! As you progress through the game, you unlock chapters in Rosalina's Storybook (the game will tell you this). Simply go into the Library (it's on the way to the Kitchen, by the warp), and you will immediately be put into a cutscene on the first time.
A Royal Gift	Receive extra lives from a letter. Simply talk to the mail toad to get some lives from Peach. He's by the Garage before you get the Fountain Grand Star, and right in front of Rosalina after. He is purple and has a "Mail" icon above him when nearby, and has a chime going along with it as well.
Lumaroth	Use the purple luma to summon or move comets. You might have to do this if no comets show up and you need one. Depending on how you play, you might never even need it. This isn't missable as the Luma is always here, even after fully completing the game.

Welcome to the Terrace! This is the first dome you will enter and is home to five Galaxies.

These are as follows:

• Good Egg Galaxy (unlocks after 1 star) – Has 5 missions
• Honeyhive Galaxy (unlocks after 3 stars) – Has 5 missions
• Loopdeloop Galaxy (unlocks after 5 stars) – Has 1 mission
• Flipswitch Galaxy (unlocks after 7 stars) – Has 1 mission
• Bowser Jr.'s Robot Reactor (unlocks after 8 stars) – Has 1 mission, the Grand Star mission

Outside (see Hungry Luma):

• Sweet Sweet Galaxy

Title	Guidance & Insights
Over Easy	Obtain every non-Purple Comet star in Good Egg Galaxy. Good Egg Galaxy has 5 missions: Dino Piranha (main mission) A Snack of Cosmic Proportions (main mission) King Kaliente's Battle Fleet (main mission) Dino Piranha Speed Run (prankster speedy comet, unsurprisingly is the first mission quickly) Luigi on the Roof (requires rescuing Luigi, then talking to the Mail Toad to receive this letter)
Prehistoric Conservation of Angular Momentum	Defeat Dino Piranha in Good Egg Galaxy without using the spin more than four times. Challenge: The wording here is that you need to only spin when necessary. You must hit him 4 times by spinning his rocky tail. You cannot waste a spin. If you mess up, you need to die and re-spawn. The indicator will disappear once you spin for a 5th time. Note that there is a one-up on the planet before Dino Piranha, behind the platforms with the Octogoombas. Collect that to avoid a game over. You are given the achievement after the boss fight if the requirements are met, so don't worry about accidentally spinning after the fight. Fail Conditions - If you spin for a fifth time Achievement Tracking - A Trigger Indicator shows up after the cutscene when you hit Dino Piranha
A Jump of Cosmic Proportions	Retrieve the star in "A Snack of Cosmic Proportions" without assembling the pull star. Challenge: On the final planet in this mission, you will be on a star with 5 blue shards. You can simply long jump to middle from one of the 5 corners. To do this, run towards the star, then press "Z" then "A" quickly. I think holding A takes you farther, but at the very least, keep holding the control stick forward. You cannot die on this planet, so if you miss, just try again until you get it. Fail Conditions - Collecting the pieces and spawning the pull stars will make the indicator appear and invalidate the achievement Achievement Tracking - A Trigger Indicator will show up once you land on the planet
Kalimari Koins	Collect 15 coins during the battle with King Kaliente in Good Egg Galaxy. Challenge: You can use a star bit to hit the blue Lava Bubbles and get 2 coins each (one at a time). There are 7 on the ground, so you need to collect the rest from at least 4 of the 6 that spawn. Make sure you start the fight before collecting the coins in the yellow dots on the ground. Coins prior to starting the fight won't count. Fail Conditions - Dying; however, you can restart when you respawn, you don't need to exit the level Achievement Tracking - A Trigger Indicator will show up when you start the fight - A Measured Indicator will indicate total coins collected
Setting a Fossil Record	Complete "Dino Piranha Speed Run" in Good Egg Galaxy in less than 2 minutes. Challenge: You are normally given four minutes to do this, but you have to now beat it in two. This one can get a bit tight, so it may take some practice to do. ▶️ Watch Video Walkthrough Fail Conditions - When the timer at the bottom of the screen reaches 2:00 Achievement Tracking - A Trigger Indicator will show up once you start the mission
Sunny Side Up	Complete "Purple Coin Omelet" in less than 1 minute and 30 seconds. Challenge: This mission is not normally timed, so you just need to do this quickly. This mission doesn't require any fancy movement, just efficiently going from one place to the next. Note that several coins are in the secondary launch star you can fly into between planets. There is a leaderboard timer active to see how long you've taken so far, so just keep an eye on that to see how much time has elapsed. You need to collect the star to finish the mission. Note that this mission unlocks after you beat the game. Route: Get the coins on the first pear planet. Use the star to head to the next planet, then spin to use the launch star along the route. Don't go directly to the red rock planet. Collect the coins on the egg planet, then do the same as before. Use the launch star, then use the launch star again to get back to the red rock planet. Finally, get the coins on that planet, and use the launch star and then the launch star again to land back on the pear planet. Then, go forward and collect the star! ▶️ Watch Video Walkthrough Fail Conditions - When you spend more than 1 minute and 30 seconds in the mission Achievement Tracking - A Trigger Indicator shows up when the mission starts
Up, Up, and Away	Obtain the star in "Luigi on the Roof" without entering the orange pipe. Challenge: There are a few ways to do this. A triple jump is probably the easiest, but you can also likely backflip up as well. You can clearly see Luigi on top of the house before you go in. Typically, people also wall jump off the side. ▶️ Watch Video Walkthrough
Honeypot	Obtain every non-Purple Comet star in Honeyhive Galaxy. Honeyhive Galaxy has 5 missions: Bee Mario/Luigi Takes Flight (main) Trouble on the Tower (main, unlocks Hungry Luma galaxy) Big Bad Bugaboom (main) Honeyhive Cosmic Mario/Luigi Race (cosmic prankster comet) Luigi in the Honeyhive Kingdom (requires rescuing Luigi)
Breaking the Buried Boulders	Collect 54 star bits in the secret pipe chamber on the starting planet in Honeyhive Galaxy without using the rainbow star. Challenge: The pipe is on top of the hill by the swing. To the right of the swing, hop up and behind, wall jump up, and defeat the piranha plant to head in the pipe. Inside, there are a bunch of rocks with a red core. Spin this core to break it open, revealing some star bits. At the bottom is an invincibility/rainbow star, you must not use it to beat this challenge.
Beeautiful Buzzkiller	Defeat Bugaboom in "Big Bad Bugaboom" without losing the Bee Mario transformation. Challenge: You lose the power-up if you take damage or touch water. Just avoid both. If you die, you can get back to the boss fight and try again, you do not have to leave the level. Fail Conditions - Losing the bee suit Achievement Tracking - A Trigger Indicator shows up when you start the boss fight
A Cosmic Leap of Faith	Complete "Honeyhive Cosmic Mario Race" without entering the slide area. Challenge: Typically, Cosmic Mario goes up behind the waterfall and down the slide. You must avoid this. Where the title comes in is that you can long jump behind the fountain where the big coin is in the first mission and land on the area below. See the attached video for an example of this. Note that, while in long jump form, you can move your control stick to have quite a lot of control over where he lands. Use this to your advantage. ▶️ Watch Video Walkthrough Fail Conditions - Going above or on the slide Achievement Tracking - A Trigger Indicator will show up when you enter the mission
Surf's Up	Complete "Surfing 101" in less than 1 minute. Challenge: You need to do this quickly, of course, but there are some tips. I'll leave linked a video of someone providing some tips and advice on mastering this. Note that it was on the Switch remaster, but the surfing advice still applies. ▶️ Watch Video Walkthrough
Flip Flopper	Complete the flip panel puzzle in "Painting the Planet Yellow" without jumping. Challenge: This one might seem difficult, but isn't too bad. The only frustrating part is the purple guy spitting the red rings. You only have 2 coins in the entire mission, so you effectively have 5 health. Note that you can (and have to) jump AFTER the planet turns green (wait, I thought we were turning it yellow?) Fail Conditions - Jumping Achievement Tracking - A Trigger Indicator will show up when you start the mission - A Measured Indicator will tick up as you change tiles to yellow
Legged It Out	Defeat Megaleg and obtain the Grand Star in the Terrace as Mario. Progression, can't be missed.
Forbidden Calf Ritual	Defeat Megaleg and obtain the Grand Star in the Terrace as Luigi You will get this beating the game as Luigi.
Ain't Got No Time for Leg Day	Destroy Megaleg in less than 1 minute. Challenge: The quickest way to do this is to have a bullet bill break the first gate, then when the new ones come up, back flip over those and have it directly go into the glass. One minute is not a lot, but you can do it if you work efficiently. You can get squished by Megaleg's mega leg to die quickly. This also has a leaderboard, so you can use that timer to see how long you've spent. Once it passes 1 minute, it's too late. Fail Conditions - More than 1 minute elapses Achievement Tracking - A Trigger Indicator shows up after the cutscenes

Title	Guidance & Insights
Killing It for Kesseler	Obtain every non-Purple Comet star in Space Junk Galaxy. Space Junk Galaxy has 5 missions: Pull Star Path (main) Kamella's Airship Attack (main) Tarantox's Tangled Web (main) Pull Star Path Speed Run (speedy prankster comet) Yoshi's Unexpected Appearance (you can get here during Tarantox's Tangled Web)
Faith in the Unseen	Collect all 5 silver stars in the final area of "Pull Star Path" in less than 35 seconds. Challenge: In the final area of this mission, you must collect 5 silver stars. This likely requires enough background knowledge of where all the paths are, so feel free to practice it before attempting it. Dying restarts the challenge, you don't need to restart the level. Fail Conditions - Taking more than 35 seconds Achievement Tracking - A Trigger Indicator will appear as soon as you land
Air Pirate	Locate Kamella's treasure hold. Bonus: You will find this in mission 2, "Kamella's Airship Attack" of Space Junk Galaxy. As this is supposed to be a fun challenge, I will be hiding it under a spoiler, but this is a guide, so I will include it anyway. At least try, y'know? I told you what mission it was in at least. Spoiler, Location On the ship with the koopas you need to throw, don't fall down. Long jump and grab the pull star, and drop down. You will slide and see all of the star bits. You can also ground pound the grate below where you fly in.
The Magic of Pitch Counts	Defeat Kamella in Space Junk Galaxy without throwing more than two shells. Challenge: You typically need to throw the shell three times. However, you can just hold a shell and run into her to make her take damage. Do this after the first hit. Note that you also take damage so don't have 1 health left. Fail Conditions - Throwing a third shell Achievement Tracking - A Trigger Indicator will show up when you start the fight
I Get by with a Little Help from My Friend	After releasing Tarantox from his cocoon, defeat him without attaching Mario or Luigi to more than seven sling pods. Challenge: Typically, this requires, at minimum, 8 slings from Mario/Luigi. So, who is the friend? Well, Toad can help out! If you interact with toad at all, he will simply fall down, so go left to avoid him. All you need to do is slam into Tarantox's butt, then hit the 3 red belly buttons. Have toad hit one of these and Mario/Luigi the final 2. Note that this means you cannot miss. Note that just getting inside a sling pod ticks the counter, not just flying with it. Fail Conditions - Getting inside a sling pod more than 8 times Achievement Tracking - A Trigger Indicator shows up when you start the fight
Pull Star Pace	Complete "Pull Star Path Speed Run" in less than 2 minutes and 20 seconds. Challenge: You normally have 4 minutes to do this. Do it quickly to get this achievement. Fail Conditions - When the timer hits 1:40 Achievement Tracking - A Trigger Indicator shows up when you start the mission
Refuse to Slow Down in Space	Complete "Purple Coin Spacewalk" in less than 1 minute. Challenge: Another speedrun. You normally have 2 minutes, so you need to do it with 1 minute left. The timer still ticks down after you get all 100 coins, so make sure you leave time for that. ▶️ Watch Video Walkthrough Fail Conditions - When the timer hits 1 minute Achievement Tracking - A Trigger Indicator shows up when you start the mission
Hip Hip Hooray It's Goomba-Stomping Day!	Earn a 1-up from stomping Goombas on the Yoshi Head planet in Space Junk Galaxy. Challenge: After you stomp on 8 Goombas, you start earning one ups. Gather a bunch nearby and start jumping. Use spins to help you out. This happens in the "Mysterious Appearance of Yoshi" mission.
Fore!	Complete the course in "Rolling in the Clouds" in less than 40 seconds. Challenge: Dying restarts entirely so don't worry about need to exit and come back. Good ol' fashion speedrun. ▶️ Watch Video Walkthrough
Bitsballer	Complete "Rolling in the Clouds" with 125 more star bits without dying. Challenge: Dying does not reset your star bits, so you have to leave and come back if you die (you could also get rid of all your star bits, die, and restart that way, but leaving and coming back is probably easier and quicker). My suggestion is to not die, of course, but specifically take your time. Unlike on the Manta Ray, you can point at the screen for your cursor to come up and collect star bits. Problem, if you are playing as intended (with a Wii Remote), you will rapidly go forward. You can likely follow the star bits from the coins and get a lot, but the rest might be tricky. Fail Conditions - Dying with multiple star bits Achievement Tracking - A Trigger Indicator shows up if you spawn in (or fly in) with 0 star bits
Battlerock and Roll	Obtain every non-Purple Comet star in Battlerock Galaxy. Battlerock Galaxy is our first special galaxy with 6 total missions: Battlerock Barrage (main) Breaking into the Battlerock (main) Topmaniac and the Topman Tribe (main) Topmaniac's Daredevil Run (daredevil prankster comet) Battlerock's Garbage Dump (bonus, found in Breaking into the Battlerock) Luigi under the Saucer (Luigi mission, requires rescuing him and reading the letter)
Battlerock Bonzana	Collect 60 star bits on the moving platform in "Battlerock Barrage" or "Luigi under the Saucer." Challenge: There are a lot of star bits on the walls, and the big ? coin has a bunch as well. Several star bits will land on the platform as well. You need to collect nearly ever star bit you can. You have until the platform stops. Fail Conditions - If the platform stops before you reach 60 Achievement Tracking - A Trigger Indicator shows up when you spin the gear to start the platform - A Measured Indicator will occasionally show your total
Molecular De-Chomposition	Destroy all six chomps on the molecule planet during "Breaking into the Battlerock" or "Battlerock's Garbage Dump." Challenge: Use the invincibility star and run into all the chomps. Ignore the star bits if you need to. You should have enough time if your only focus is the chomps. Achievement Tracking - A Measured Indicator will update as you break the chomps
The Juice Is Loose	Free the luma from the crystal in "Breaking into the Battlerock" on the first cannon shot. Challenge: Typically, the Luma is inside two tiers of glass. If you miss, you gotta get into the other cannon and try again. You need to time and line up properly to be right in the middle on the first time. Fail Conditions - Using the cannon at all and missing Achievement Tracking - A Trigger Indicator shows up when you enter the room with the Luma
Torqued	Defeat Topmaniac in less than 12 seconds. Challenge: Speedrun! Time starts after the cutscene. This works in either the main or Daredevil mission, if you want an extra challenge. There is a leaderboard timer as well that you can use to track your time. ▶️ Watch Video Walkthrough Fail Conditions - Taking more than 12 seconds to beat Topmaniac Achievement Tracking - A Trigger Indicator shows up after the cutscene
Sleeping Satellite	Obtain the star in "Shrinking Satellite" without jumping. Challenge: Die if needed. You need to do the entire mission, not just the last planet. Fail Conditions - Jumping Achievement Tracking - A Trigger Indicator starts when you start the mission.
Timed Reaction	Defeat Bowser and obtain the Grand Star in the Fountain as Mario. Progression: Can't be missed.
Splish Splash	Defeat Bowser and obtain the Grand Star in the Fountain as Luigi.
Turtle Toppling 101	Defeat Bowser in Bowser's Star Reactor without letting him recover from any of his burnt tail or spin out states. Challenge: If you don't swing at Bowser while his tail is on fire quick enough, he will put out his tail's flame and go back to chasing you. Similarly, he will exit his spin after a few cycles. Generally, there is no real rush here, but you might mess up your first time though. Fail Conditions - Bowser's burnt tail burns out - Bowser's spinning stops Achievement Tracking - A Trigger Indicator shows up when Bowser first appears

Welcome to the Kitchen! Now, it's time to cook. This is the third dome, unlocked after beating Bowser in the Fountain.

The Kitchen has 5 galaxies:

• Bubble Breeze Galaxy (unlocks after 19 stars) – Has 1 mission
• Ghostly Galaxy (unlocks after 20 stars) – Has 5 missions

• Bowser Jr.'s Airship Armada (unlocks after 23 stars) – Has 1 mission, the Grand Star mission

Outside (see Hungry Luma):

• Drip Drop Galaxy

Title	Guidance & Insights
Formiddable Freestyle	Obtain every non-Purple Comet star in Beach Bowl Galaxy. Beach Bowl has 5 missions: Sunken Treasure (main mission) Passing the Swim Test (main mission) The Secret Undersea Cavern (main mission) Fast Foes on the Cyclone Stone (fast foe prankster comet) Wall Jumping up Waterfalls (bonus star, accessible in either mission 2 or 3, but 3 is recommended)
Arborist	Retrieve the star in "Sunken Treasure" without assembling the launch star. Challenge: Typically, you must collect 5 star pieces in the ocean to open the launch star and fly up to the top. You can skip this by back-flipping off the tree. See the video for an example of this. ▶️ Watch Video Walkthrough Fail Conditions - Assembling the launch star Achievement Tracking - A Trigger Indicator shows up when you start the mission
Following the Tunes of the Beach	Obtain the note challenge 1-up mushroom during "Sunken Treasure" in Beach Bowl Galaxy. Challenge: Once you use the launch star (or don't, see the below achievement), to get to the top layer, you will see a big ? Coin, collect it to see notes appear. Collecting all of these spawns a 1-up, grab it to collect this achievement.
Pool Shark	Complete "Passing the Swim Test" in less than 1 minute. Challenge: You must collect the golden shell and bring it to the teacher in less than one minute. Note that the shell does not spawn until you initially talk to the penguin; however, the penguins swimming around are still there. If you can spot them, swim to them quickly after the shell spawns. You can keep spinning to swim faster, there is no cooldown on spinning while swimming. Once you grab the shell, don't swim, as you will throw the shell. However, you do still swim quickly, so start going up and walk over to the penguin. Timer starts when you start the mission, there is a leaderboard you can use as well to track your time. Fail Conditions - More than one minute elapses Achievement Tracking - A Trigger Indicator shows up when you start the mission
Leap of Faith	Collect the 1-up mushroom near the Cyclone Stone's rotating platforms by jumping to it from the high ground near the start. Challenge: In "The Secret Undersea Cavern" (or the "Fast Foe" mission, I suppose), walk forward and you will see a 1-up above some rectangle platforms that move back and forth. A precise long jump can just barely reach. Try to long jump as it's coming towards you, as it might be gone by the time you land.
Bubblicious	Collect 40 star bits while launching to the second part of "Through the Poison Swamp." Challenge: There are a bunch of star bits as you fly between the two areas. Just collect a bunch in the air and you'll be good. Just get ready when you use the launch star!
Scrambling on the Rocks	Complete the second part of "Through the Poison Swamp" without entering a bubble. Challenge: Speedrun trick! Except, don't worry, it's quite easy. A simple backflip onto the rocks and then a long jump over to the star is all you need! You will more than likely undershoot it than overshoot it. Be careful of the bombs as they can knock you into the poison. ▶️ Watch Video Walkthrough Fail Conditions - Getting into any bubble Achievement Tracking - A Trigger Indicator shows up when you start on the second planet
Master of the Mansion	Obtain every non-Purple Comet star in Ghostly Galaxy. Ghostly Galaxy has 5 missions: Luigi and the Haunted Mansion (main mission, unlocks other Luigi missions) A Very Spooky Sprint (main mission) Beware of Bouldergeist (main mission) Bouldergeist's Daredevil Run (daredevil prankster comet) Matter Splatter Mansion (secret mission)
Unpalatable	Kill the chomp guarding the haunted mansion. Challenge: You can kill him with an invincibility star found in one of the rocks on the first planet.
Boo's Booty	Collect all 48 coins in the haunted mansion's secret library. Challenge/Secret: While you are collecting the star pieces to progress in "Luigi and the Haunted Mansion," you will notice a cracked section on the roof. Ground pound this to enter the room to find a bunch of sling stars. You will also see a big ? Coin, collect it, then quickly use the launch stars to collect the coins.
Ghost Buster	Rescue Luigi from a paranormal predicament. Progression (towards 100%), can't be missed. Just beat "Luigi and the Haunted Mansion" to earn this one.
Speedy Specter	Complete "A Very Spooky Sprint" in less than 1 minute. Challenge: Note that this only considers the in-game time. Before you start the race, head through the race until the end where there are a bunch of floating mines. Use your star bits to destroy them, then head onto the goal planet and find the pipe to go back. Then, when doing the race, go to the sling star to skip a significant portion of the race. Now, the final part is easier, so you can quickly go through it, and beat the race.
Diamond Hands	Defeat Bouldergeist without damaging his hands. Challenge: The first phase is free since there are no hands. As for the second, when they actually spawn in, the easiest way to do this is to be close to Bouldergeist when he launches the rocks. That way, you can swing the Bomb Boos right into him. I recommend constantly circling close to him. ▶️ Watch Video Walkthrough Fail Conditions - Damaging the hands Achievement Tracking - A Trigger Indicator shows up when you start the boss fight
As a Matter of Fact	Collect 80 star bits in the "Matter Splatter Mansion." Challenge: This is in the secret mission, which is accessible in main missions 2 and 3 by breaking the glowing rock near the ledge to the right. The star bits mostly come from the end ?

Ideally, you get a Bee Mushroom up to the top of the planet, and fly over. Below is the ONLY video I could find about this. I will replace this with my own when I get it, and a more detailed video too. ▶️ Watch Video Walkthrough
Busy Buzzing All Day Long	Complete "When It Rains, It Pours" without losing the Bee transformation. Challenge: Touching rain or taking damage loses the power-up, so just tread carefully. Note that going into a bubble also makes you lose the power-up. Fail Conditions - Losing the Bee transformation Achievement Tracking - A Trigger Indicator shows up when you start the mission
Mind the Gap	Defeat Undergrunt Gunner in "When It Rains, It Pours" without being damaged or raising the platforms. Challenge: You can get bubbled and spin and all that so don't worry too much here.

Timberland Treasure Trot	Complete "Purple Coins in the Woods" in less than 2 minutes and 30 seconds.

Hop up the orange block, go to the yellow block, and sneak and head in the tiny gap under the slope.
Avoiding Assimilation of Mechanical Means	Complete "Heavy Metal Mecha-Bowser" as Mario without collecting a Spring mushroom. Challenge: You don't need it at all! You can backflip-spin up most of the first area where you are introduced to it. The hardest planet might be the one where the star is inside the bottle. Luigi can get up here a lot easier, but Mario should be able to as well. Finally, some triple jumps and backflips will get you to the top to finish off the boss! Note for below, you don't need to do the silly wall-jumping stuff, you can just play the level like normal. ▶️ Watch Video Walkthrough
Brotherly Love	Collect 30 star bits during the launch off the first train in "Mario Meets Mario" (or "Luigi Meets Mario") before landing. Challenge: There's 20 in the each heart by the red pencils.

An Unshocking Turn of Events	Defeat Undergrunt Gunner in Toy Time Galaxy without taking damage or losing the Spring power. Challenge: Taking damage does lose the Spring power; however, you don't need it at all. I recommend it up until the boss, but you can simply backflip-wall jump-spin up to the top and ground pound him like normal. Just avoid getting hit. Also be wary of him charging up which will damage you. Below video is an example of the boss without needing the Spring. ▶️ Watch Video Walkthrough
Leaping to New Heights	Complete "Bouncing Down Cake Lane" as Luigi without collecting a Spring mushroom. Challenge: This requires a surprisingly tight triple jump on the first planet. You can easily backflip and spin up to the top of the undergrunt gunner at the end. ▶️ Watch Video Walkthrough Fail Conditions - Using a spring mushroom - Dying past the second planet Achievement Tracking - A Trigger Indicator when you start the mission as Luigi, or re-spawn as late as the start of the second planet
Never Break the Chain	Complete the flip panel puzzle in Toy Time Galaxy without changing any yellow flip panels back to blue. Challenge: Just like in the prologue, don't step on any yellow panels.

The Master Maker	Complete "Luigi's Purple Coins" having collected all 150 purple coins. Challenge: It's recommended to use Luigi here as you get more control and distance, but it's possible with Mario as well. You need to collect every single coin and then make it back to the star. The hardest part are the floating 5 coins as you only get one shot. The provided example shows Mario. Note that this mission requires beating the game and the Good Egg Galaxy purple coin mission to appear. ▶️ Watch Video Walkthrough
Luigi's Enlivened Leaping	Complete "Luigi's Purple Coins" in Toy Time Galaxy in less than 2 minutes. Challenge: You typically have 3 minutes, so make sure you get the final coins near the platform so you can make it back in time.

Simmering Anger Issues	Defeat King Kaliente and obtain the Grand Star in the Engine Room as Luigi. You will get this beating the game as Luigi.
Held the Hexagon	Defeat King Kaliente in Bowser Jr.'s Lava Reactor without depressing any platforms other than the starting one. Challenge: This one is tricky, you cannot leave the platform you start on. However, the platforms stop depressing once he is defeated, so don't worry about needing to get to the star. Constantly jump and spin to avoid your platform disappearing. I highly recommend grabbing that life shroom. You can, however, be above the platform, just make sure you either fall into the lava or make your way back. You can't step on any other platform at all. Fail Conditions - Whenever any other platforms other than the starting one depresses Achievement Tracking - A Trigger Indicator shows up when you start the fight

You'll get a special line of dialogue. ▶️ Watch Video Walkthrough Fail Conditions - Collecting any purple coin Achievement Tracking - A Trigger Indicator shows up when you start the mission

Chowed Down	Obtain all seven stars from Hungry Luma galaxies.
Whirling Dervish	Cross the rotating platform in "Rocky Road" without jumping or spinning. Challenge: This mission is in the Hungry Luma mission outside of the Terrace. The rotating platform this is referring to is the brown platform after you talk to the toads. You will be heavily tempted to spin and jump, don't do it.

Graduate Level Turtle Toppling	Defeat Bowser in Bowser's Galaxy Reactor in less than 2 minutes and 15 seconds without being damaged. Challenge: The hardest one is when he turns into a ball. You need to swing and hit him like you would the red area of a normal ball. It's the easiest to get hit here, thankfully it's also the first one. The rest isn't too hard to avoid, you just need to be quick. Tip for the second planet, you can spin the plant into Bowser at any time, not just in his spike form. Hit in if he's near one to save some time. Fail Conditions - Taking damage - Taking more than 02:15 Achievement Tracking - A Trigger Indicator appears when you land on the final planet before Bowser, or after you start the cutscene with him if you died

This is a bit of a misc category since it contains all the transformations. You are typically introduced to these in their introductory Galaxies, so these are hard to miss. I will list off each Galaxy these occur in, just in case.

Title	Guidance & Insights
Prismatic Plumber	Transform into Rainbow Mario. In a few Galaxies, but first in mission 2 of Honeyhive Galaxy, you will find a Rainbow star. Collect it, and you will start running and instantly killing any enemies!

Ah, those prankster gangster comets. You will get all of these in a 100% play-through, so don't worry too hard about getting them. Regardless, I will list each Galaxy these are possible to get in. Unlike in Mario Galaxy 2, you don't need to do anything special to unlock the comets (outside of Purple Coin comet, which requires beating the game), you just need to get enough stars.

Title	Guidance & Insights
Hedgehog Cosplay	Obtain a Speedy Comet's star. This is the first comet you are introduced to. These comets require you to beat a previous mission quickly, typically with harder obstacles. It has a red comet tail. It appears in four Galaxies: Good Egg Galaxy (Terrace) Space Junk Galaxy (Fountain) Dusty Dune Galaxy (Bedroom) Dreadnought Galaxy (Garden)
Living on the Edge	Obtain a Daredevil Comet's star. These comets require you to do the mission without taking any damage. It has a white comet tail. It only appears in five Galaxies: Battlerock Galaxy (Fountain) - Beat Topmaniac Ghostly Galaxy (Kitchen) - Beat Bouldergeist Gusty Garden Galaxy (Bedroom) - Beat Major Burrows Deep Dark Galaxy (Garden) - Beat Kamella Melty Molten Galaxy (Garden) - Do the entire "The Sinking Lava Spire" mission
This Time It's Personal	Obtain a Cosmic Comet's star. These comets require you to race your Cosmic Clone. It has a blue comet tail. Note that Luigi has a faster and more difficult race. It appears in four Galaxies: Honeyhive Galaxy (Terrace) Freezeflame Galaxy (Bedroom) Gold Leaf Galaxy (Engine) Sea Slide Galaxy (Engine)
Think Fast	Obtain a Fast Foe Comet's star. These comets require you to do a mission with everything moving much faster. It has a yellow comet tail. It appears in two Galaxies: Beach Bowl Galaxy (Kitchen) - Do the Stone Cyclone section Toy Time Galaxy (Bedroom) - Do the secret Hungry Luma mission
Coinstallation for Comet Collection	Obtain a Purple Comet's star. These comets require you to get 100 purple coins. It has a purple comet tail. Note that these do not unlock until after you beat Bowser in the Center of the Universe for the first time. Every Galaxy with multiple missions has a Purple Coin mission, so I won't be listing them all. I will, however, list the ones with special requirements. Clicking the name will take you to the achievement in this guide to see more info. Note that for timed missions, the timer still ticks down after you get all 100 purple coins. Good Egg Galaxy (Terrace) - Sunny Side Up Space Junk Galaxy (Fountain) - Refuse to Slow Down in Space Gusty Garden Galaxy (Bedroom) - Hedge Fund Gold Leaf Galaxy (Engine) - Timberland Treasure Trot Toy Time Galaxy (Engine) - The Master Maker and Luigi's Enlivened Leaping Deadnought Galaxy (Garden) - I'm Not Impressed by Your Performance

Everything else. You will likely get these as you play, but I'll leave tips just in case.

Title	Guidance & Insights
Superish Mario	Obtain a Life Mushroom. These are all over the place, typically appearing before a boss. The earliest is either in "King Kaliente's Battle Fleet", mission 3 of Good Egg Galaxy, in a box right before the launch star. It is also just chilling in "Trouble on the Tower", mission 2 of Honeyhive Galaxy, on the lower level below the windmill.
Filled the Starry Sky	Obtain 120 stars as Luigi.
The Spark of Stardust	Earn a 1-up from collecting star bits. You earn one every 50 star bits.
Head Start	Collect ten star bits during the initial fly-in to a galaxy. You will probably get this naturally. I will update this as people provide advice for the best Galaxies, if you really need it.
So Long, Petari	Defeat a Tracks. These enemies usually appear in sand and leave "tracks" (hence the name), they briefly appear if you don't move but disappear when you do. Spin them to stun them, then run into or spin them again to defeat them, and enjoy a bunch of star bits! They appear in these Galaxies: Gateway Galaxy - Gateway's Purple Coins Good Egg Galaxy - Dino Piranha and its speedrun (same spot) Gusty Garden Galaxy - Bunnies in the Wind and Gusty Garden's Gravity Scramble (and the secret) Sea Slide Galaxy - The Silver Stars of Sea Slide (and the secret) Deep Dark Galaxy - All main missions
Speed Boost!	Perform a speed boost at the start of a Cosmic Mario or Cosmic Luigi race. At the start of a Cosmic race, hold "up" on the control stick, then press "Z" (crouch) whenever the timer hits "2," then hit "A" (jump) when the race starts. Mario/Luigi will turn yellow and go really fast for a brief time.
Major Melons	Turn coconuts into watermelons. This happens after you obtain 9999 star bits. If you need a place to grind, you can go to Sling Pod Galaxy (Fountain Hungry Luma) and collect all the white star bits. There are so many here, just keep dying to re-spawn them. Note you can only get 999 star bits at a time per mission, so you'll need to do this several times.

Super Mario Galaxy offers several leaderboards. Most notably for the races, but also several boss fights and timed speedy levels.

You will typically see a timer in your emulator regarding your speed time. It will not show up if there is already an in-game timer, but it will still submit.

For all of these, timing starts when you start fighting the boss. This might be the first cutscene, depending on the boss. Time stops when you defeat the boss.

You will see a stopwatch indicating your elapsed time inside your emulator.

Yea, hah, hah, hah, hello! These are the leaderboards for the cosmic races.

For these, time starts when the race starts and ends when you collect the star. It will be canceled if you die (or leave the level) or Cosmic Mario/Luigi beats you.

Speedy (and some Purple) Prankster Comets have a timer that ticks down that you need to complete the mission in time for.

The time starts when the timer in-game starts and ends when you collect the star. Exiting the level or dying will cancel the submission. Dying resets the level so you don't have to leave and come back.

There are a handful of missions with a timed race. This time appears in-game on the mission screen and your total missions.

The tracked time already shows up in-game, so whenever that starts and stops is what is tracked for the leaderboard.

These are all unique challenges with achievements tied to them. There is no in-game timer or countdown with these achievements, they are solely added as extra challenges.

They all have an emulator stopwatch to see how long you've progressed.

For all of these leaderboards, your submission is canceled if you die or leave the level.

These leaderboards are not time-based and are instead scored uniquely.
