The Crazy Dolphin is a recurring character in the series. He debuts in the episode "Treasure Island Tricks" and makes six subsequent appearances.


The Crazy Dolphin is normally locked up in a cage reserve. He inexplicably has access to several time bombs. The dolphin may have been a sailor in the past, as he mistakes the volcanic island for an enemy ship in "Waterski Hit!" and wears a sailor hat.


The dolphin has light gray skin and wears a red, white and blue sailor hat. He has one red eye and one yellow (complete heterochromia).
