Attacky Sack

An Attacky Sack is a large, rubbery, marble-like enemy from Yoshi's Story. The name is a pun on a hacky sack. It has small eyes with green irises and long sharp teeth; its body is covered in multiple patchy colors, and is thrice the height of a Yoshi. It slowly bounces off of walls and is invincible. They can only be found in Magma Castle, where five of them appear.
