Snowball Yoshi is a power-up in the games Super Mario World 2: Yoshi's Island and Yoshi's Island DS. Yoshi can gain this form by landing incorrectly in a jump as Ski Yoshi. When in this form, Yoshi is invincible, and can't jump. Players cannot control him in while he is in this form. When Yoshi bumps into an object, the snow will disappear and Yoshi will be normal again.
