Ride on drawn tracks, reach otherwise inaccessible areas.
Train Yoshi is one of the forms Yoshi and his species can transform into by touching a Morph Bubble in the Yoshi's Island series. In this form, Yoshi can move left or right, though loses his jump ability. To compensate however, Train Yoshi is able to move on train tracks drawn in the background, shrinking in size to do so. When this happens however, Train Bandits, Shy Guy-like enemies that are drawn on the wall, come to life, and can attack Train Yoshi, making him lose control for a short time. He will revert to his regular state if Yoshi touches a Yoshi Block or a timer runs out, the latter of which will take Yoshi back to where the Morph Bubble was.
