Each Big Eye is a different color. In Mushroom Kingdom Fusion, Big Eyes appear in Castle Cutman and Gutsman's Quarry as mini bosses. They can be defeated by picking up vegetables in Castle Cutman or Mushroom Blocks in Gutsman Quarry. They are also vulnerable to the Mega Buster. The Big Eyes are blue in Gutsman Quarry and red in Castle Cutman.
