Brain Gain

Overview

Yam Yam gets bumped on the head by a meteor, which makes him as clever as Pi. They both then solve problems together, but Yam Yam is unhappy because even though he is now clever he has lost his bouncing ability. Pi and Yam Yam invent a bouncing machine together so that Yam Yam can bounce again. The machine goes out of control and in the mayhem that follows he gets a bump on the head again, causing him to lose his new found cleverness, but his bounces have returned!
