Snowball Yoshi

Snowball Yoshi is a form that Yoshi uses during his adventures in the game Super Mario World 2: Yoshi's Island and Yoshi's Island DS. Ski Yoshi is needed to perform this and, if Yoshi hits a rock or obstacle, he would turn into this. He is invincible in this form, but can't jump, or get past gaps. In many ways, Snowball Yoshi is an non-positive status ailment, and is more or less just a form of being attacked.
