A large green sea serpent with a slight lisp. He is fiercely loyal to Beany but not terribly bright. Cecil's trusting
good nature invariably winds up with him being taken advantage of by the bad people, and he often ends up absorbing a great amount of physical abuse (getting smashed flat, losing his head, having his skin burned off, being shattered to pieces), all within the laws of cartoon physics. The end of Cecil's tail was never seen in most episodes; it always extended off-screen, or was hidden behind an obstacle. This is likely a joking reference to the original Cecil, a hand puppet whose tail was likewise hidden (because it didn't exist). Cecil's tail did appear in "Beany and the Jackstalk", when his entire body got wound into the tension spring of a giant cuckoo clock. Cecil also has a superhero alter-ego known as Super-Cecil. In this guise, he wears a modified Superman shirt (complete with cape). It was Cecil who cried "A Bob Clam-pett car-tooooooo-OOOOOOOOON!" at the opening of each episode. Cecil was originally voiced by Irv Shoemaker in the 60's cartoon and by Billy West in the 80's cartoon.
