Snowball

A Snowball is an item in Super Mario World 2: Yoshi's Island as well as its remake, Super Mario Advance 3: Yoshi's Island. It is only found in two levels. It is a giant snowball that Yoshi can push. Yoshi can push it in the same manner as he can a Chomp Rock. The Snowball destroys all items and enemies in its path. It keeps growing larger and larger in size until it eventually stops. It is here where Yoshi must hop on top of the Snowball to get to a platform normally out of reach.

The snowball will appear in the upcoming Super Mario Galaxy 2.
