• Tail Flick – Put creatures or objects on Yoshi’s back with a flick of the tail. Repeat the move to throw or perform a special action with the creature you’re carrying.
• Sprint – Move for a while in the same direction to break into a sprint. If a creature is riding on Yoshi’s back, it might react.
