Plus he’s got HYPNO-EYES. Purple is just a weird, big thing that shows up every once in a while. He’s friendlier than the fish, but he is still more a recurring character than the main protagonists. But after they realize they shouldn’t stare at him for too long he gets along with the other characters. He is childlike, but obviously intelligent, as he almost never does anything destructive or disruptive. Much nicer than Yellow.
