Mr. Super

Mr. Super is a character from the game Yeah Jam Fury and its follow-up Yeah Jam Fury: U, Me, Everybody!, who has the rare chance of appearing in the background of style levels as a giant shakey eye that looks from side to side before closing his eyelid and disappearing, only to repeat the process after a few seconds. Normally, if the level's music is absent, it is a certain hint he will appear.

Character description
In the original, he takes the appearance of a white-sclera eye with a circular purple iris and a circular dark purple pupil; in the follow-up, his appearance gets changed to that of a lemon-like appearance with a yellow-sclera eye and a horizontal goat-like black pupil. Whenever he shows up in a level, a loud thunderous noise can be heard as long as his eye is visible.

Trivia

 * Encountering him in the original game awards the player the "Who is Mr. Super?" Trochieval.
