At 1:00 when you're using the rig to animate the squash, I create a keyframe at frame 15 then add a new one at 22 then I use the rig to squash the cube. However, when I scrub back it keeps the cube squashed on all of the frames 1-22. If I try to stretch it on frame 25 then I get the same problem, all frames from 1-25 leave the cube stretched. I'm not sure what I'm doing wrong.
