Mine-Cart Yoshi

Mine Cart Yoshi is a form the Yoshis can transform into in Yoshi's New Island by entering a door with a minecart sign on it.

In this form, the Yoshi can jump to grab items, and move left and right to navigate the course. Like all forms, Yoshi only has a limited amount of time before he reverts to normal and is sent back to the door; clocks scattered about the obstacle course provide the Yoshi with more time. Going through a ring will simply return the Yoshi to normal.
