Mr. I

Mr. Is are enemies in Super Mario 64. They are large eyeballs. They attacks by shooting orbs at Mario upon focusing on them. They are defeated by being circled

around. There is also a boss variant known as a Big Mr. I that appears in Big Boo's Haunt. Mr. I enemies can be found in Big Boo's Haunt, Lethal Lava Land, and Hazy Maze Cave.

Red Eye
In some personalized copies, the blue part of Mr. I is red. This usually makes it take longer to defeat the Mr. I, and makes the orbs the Mr. I shoots more damaging.
