Red I

A Red I is a strange enemy that has only appeared in Super Paper Mario, in Castle Bleck. As the name implies, it is a sub-species of Mr. I, except it has more of a red hue. Like their relative, a Red I attacks by shooting lasers from its pupil. They are impervious to damage, but Mario can make them dizzy and defeat them by running in a circle around them. Alternately, Fleep's ability also works.
