2D Squash & Stretch Animations

Here is x2 2D squash and stretch animations I did; one of a cubie character, one of a ball.

I found it quite hard to do when adding the top bobble and animating it. I thought back to the millennium when everyone at my school wore them in a 'millennium party' which helped me picture how they move. I did it in 7 frames.

Here is a animation of a ball squash & stretching. I did it in 4 frames and just looped it back and forward.
