Flung and flitzel

Flung and Flitzel, two examples of Flenguins.

A Flenguin is a penguin-like creature only seen within Chowder's head. A few of the flenguins he encountered resembled his friends, such as Flung and Flitzel, both of whom are Mung and Shnitzel's flenguin counterparts. In "The Brain Freeze", these flenguins were created by Chowder's mind to help guide him on his quest to thaw his brain.
