MadBalls were a series of rubber balls with crazy and sometimes disgusting faces. After the initial series of balls, there was a series of figures released. The figures had a plastic body and a post for the rubber ball head to sit on. The hole in the head had a spring in it, and when you pressed a button on the back of the figure’s torso the head would pop off. I had a mummy figure called Dust Brain, and I thought he was pretty cool.
