Mr. I

Mr. I is one of the more spooky-oriented species in the Mario universe. Its name is self-descriptive; it seems to be nothing more than a giant eyeball. The only thing it can do is spit strange, white globules at Mario. It always keeps its eye on Mario, and can be dizzied into submission if Mario runs in a circle around it, rewarding Mario with a Blue Coin. Mr. I first appeared in Super Mario 64.

Later Mr. I appeared in Mario Party 2 and, of course appeared in Super Mario 64's remake. Mr. I also appeared in Mario Party Advance.
