Yoshi Block

The Yoshi Blocks are blocks that appears in Super Mario World 2: Yoshi's Island and Yoshi's Island DS that have the face of a Yoshi, depending on the Yoshi color. When a Yoshi tranforms into a vehicle (using Morph Bubbles); the tranformation won't last very long, so the tranformed Yoshi must touch one of the blocks to turn back to normal. If the transformed Yoshi didn't touch this block on time, the Yoshi is forced to go back to the place that has a Morph Bubble and has to start over again.
