Overlapping example video

I found an example for the overlapping action that can be observed mostly on the tail which reacts like a squirrel tail. The tail is braked in 3 or 4 joints that follow the ball but they are made in a way that not every single joint copies the main movement, because it is not a pendulum it's a tail and it has somehow its own role (to maintain the balance).
Because of the tail, the ball creature has personality and looks really funny at the end.
