Elastic trick

This diagram by qualet shows how to convert an elastic trick from Blockbuster mod to BBS mod:

The elastic trick is what's known something like you can see in AnimalMace's Shorts (watch the first 5 seconds, check out Daisy's bounciness animation). This is done by creating two morphs, one that scales down and widens the model by XZ axes, and another one that resets the pose.

Both of them have Elastic Out interpolations, and same duration, for example 35 ticks, but the shift between Morph actions is very small like 5 ticks. This creates bounciness effect. The way this trick works is limiting the overshoot in the first morph, so that you get only the juicy part of the animation, and then transitioning into a full Elastic Out:

Limited frame rate animation

You can achieve stop-motion like animation, by using Step and Constant interpolations for keyframes. With Step interpolation, it's possible to use the additional arguments (number fields under the graph) to control how many steps there are, the easing, and rounding function:
