A simple exercise and some further research.
After the object stops moving, the attachment follows and continues to move. This is the Follow Through in animation. And a temporal dislocation of a subject from another part in the same transformation is called Overlap. The purpose of this animation is to practice both of these points.
Tail animation is a good practice. It is divided into four joints, each of which lags behind due to Overlap and Follow Through. The tail of the example animation looked heavier and more powerful, and I wanted to try something light and soft.

I placed three platforms, each in a different vertical and horizontal position, so the ball would swerve during the jump. The Follow Through is also divided into two directions: vertical and horizontal.
When the ball takes off, the tail stays in place, and then the joints close to the body are moved first, followed by the others. The convenient way to use it is to put all joints in the same position from flat to down after the jump. The motion curve of each joint is then lagged in turn. Same thing with falling and turning.

The final result needs to be slightly adjusted. In this exercise I also changed some materials and added lights and sound.
