Attacky Sack

An Attacky Sack is a large, rubbery, marble-like enemy from Yoshi's Story. The name is a pun on "hacky sack". It has small eyes with green irises and long sharp teeth; its body is covered in multiple patchy colors, and it is roughly three times the size of a Yoshi. It is an invincible enemy that slowly bounces off walls. They are only found in Magma Castle, where seven of them appear.
