Helicopter Yoshi

A Yoshi Helicopter (sometimes known as the Yoshi-Copter) is a form the Yoshis can transform into in Super Mario World 2: Yoshi's Island by touching a Morph Bubble with its picture inside.

In this form, the Yoshi can fly around the level until he reaches the Yoshi Block or until his time as a helicopter runs out. As with other transformation, the latter will send him back to the position where touched the Morph Bubble. The Yoshi Helicopter can be controlled with the D-pad. Touching an enemy while in this form will make the Yoshi fall a short distance, unable to be controlled, which can cause the player to lose time and a life if he falls into an abyss. The form returns in Yoshi's Island DS.

In Mario Kart: Double Dash!!, a Yoshi Helicopter appears in Baby Park and Yoshi Circuit, though it is an actual vehicle instead of being a Yoshi transformation.

Trivia

 * Sprites of an unused "Yoshi plane" can be found in the game's data, possibly a beta version of the helicopter.
