Big Mr. I.

Big Mr. I is a famous Super Mario 64 character.

In Big Boo's Haunt, the little version is accessed by going to the room in front of you to the left side. However, to reach big Mr. I, you have to get up to the attic, which leads to the balcony. Mario must go to the balcony or second floor, grab the invisible cap and run into the painting in the attic. He will be in a room with Mr. I, and he must get Mr. I's attention. He must run around Mr. I a few times, and he will spin around and turn into a star.
