Big Mr. I.

Big Mr. I is a big eyeball that shoots laser beams from its pupil in Super Mario 64. In Big Boo's Haunt, the little version of Mr. I is accessed by going to the room to the left of Mario in the beginning of the leve. However, to reach Big Mr. I, Mario has to go up to the attic, which leads to the balcony. Then Mario must go to the balcony or second floor, grab the invisible cap and run into the painting in the attic. He will then be in a room with Big Mr. I, and he must get Mr. I's attention. Mario must run around Mr. I a few times, and the eyeball will spin around and turn into a star.
