Moho 12 - Squash Bones against target bones

A trick I discovered that makes leg bones squash when you push the main handle towards target bones.
First transform the leg bones so they are slightly shorter. Then push the main handle towards the leg bone targets - the legs will squash.
They now won't stretch when you pull the main handle upwards - to get IK stretching to work again you need to paste in the leg bones original scale from frame 0.
