Snowball is an item in Super Mario World 2: Yoshi's Island and Super Mario Advance 3: Yoshi's Island. It is only found in one level. It is a giant snowball, and Yoshi can push it in the same manner as he can to the Chomp Rock. It destroys all items and enemies, growing larger and larger in size until it finally gets big enough and stops; it is here Yoshi must hop on top of it to get to a platform.
