Slime Egg
The slime egg will spawn a green slime when it is right clicked on a block. The slime egg behaves like a spawn egg however it can not change spawners like a normal spawn egg can. There is also a Magma Slime Egg and Withering Slime Egg which can be used to spawn those slime types.
Powder Pouches
Powder pouches allow players to convert blocks between their different variants. For example the Purification Powder can be used on Soul Sand to convert it into normal sand. The powder items can also be used in a dispenser to automate the conversion of certain blocks. Modpacks and mods can add their own conversion recipes as well. Example recipe files can be found here
