Mad Big Boo

Mad Big Boos are enemies in Super Princess Peach and can be found in the Shriek Mansion level. Mad Big Boos act the opposite of normal Big Boos; when Peach is not looking at one, it will stop moving, and when she looks at it, it will quickly move towards her. Despite being mad, the Mad Big Boo has no frown. This suggests that the "Mad" in its name means insane or crazy. It somewhat looks like a miniature Boolossus from Luigi's Mansion.
