Bouncy blocks are square and have a neon green outer layer. When touched by a flipside, the green outer layer will glow for a split second; the middle section is grey metal track that bears a resemblance to debris.
Bouncy blocks will bounce the racer when touched. The racer will be bounced in the opposite direction that they touched it in, regardless of gravity. When touched, a spring sound will be heard. They are first introduced in level three.
