Morph bubble

Morph Bubbles are floating Bubbles found in Yoshi's Island in Super Mario World 2: Yoshi's Island and its sequel Yoshi's Island DS. When a Yoshi touches this the Yoshi will turn into a different form.

However, the transformation won't last very long; the transformed Yoshi must find a Yoshi Block or another Morph Bubble and touch it before the transformed Yoshi turns into a normal Yoshi again.
