Forum:Unknown Character

Hey everybody.

I was wondering about this character that apears in the opening, just after the camera pases trough the candy kingdom party and it's going up the tower, there's someone round shaped looking down in an angry mood. Even in the first gender swap epidsode, he changes and have a curly haircut and glasses.

I cant find anywhere who this character can be, and why he is all by himself in the tower. Is he someone important on the story? some random easter egg? (would'nt be that surprised).
