The Flipper is a giant, mutated penguin. After absorbing a bottle of space goo, Pablo turns into the Flipper whenever he gets excited about the meteor. He reverts back to his normal self by holding his teddy bear, Teddy.
The Flipper is primarily green. He sports a torn, white lab coat and a pair of ripped, brown shorts. The Flipper has a far more muscular figure than Pablo.
Pablo has played the Flipper in one episode of The Backyardigans: "The Flipper!" from season four.
