It is likely that the name "Mr.I" is a pun on eye as this foe is a huge eyeball. Mr.I has a white scalera, a blue iris and a black pupil.
Mr.I is a stationary enemy that rotates in place. If Mario gets too close to it and stays there for too long, the Mr.I will shoot fire at him in an attempt to burn Mario. If Mario gets hit by the flame, he will be on hurt and he will run around due to the burn.
How to deal with it
Mario can defeat Mr.I by running around it in circles, which at some point will make the Mr.I shrink and vanish.
In Big Boo's Haunt, there is a large Mr. I called "Big Mr.I", which is usually referred as a miniboss. To defeat it, Mario must reach the attic (read article for details) and find the room with the Mr. I, and kill it like any other enemy if the species.
Mr.Is generally appear in ghost and lava themed levels.
