Snail

The Snail is hidden in every episode (besides "Trouble In Lumpy Space"). He is seen making cameos, usually waving at the screen. His cameos may be a running gag. The table below lists his known whereabouts. It seems that when the writers wanted to fill up some space they put this happy snail in.

Trivia

 * In Righteous Quest 2, the snail appears throughout the game.
