Car Yoshi

The Yoshi Car was a form Yoshis could become in Super Mario World 2: Yoshi's Island by touching a Morph Bubble.

It allowed them to go faster, and they could stretch their wheels for a short time. It was also small enough so it could fit through small openings.

Yoshi also has various cars in the Mario Kart series, however only the Turbo Yoshi bears any actual resemblance to the Yoshi Car.
