Old Toothy is shown to be extremely vengeful. He was furious at Buttsquat for stealing one of his teeth and never stopped looking for his missing tooth.
Toothy appears as a hybrid of a whale, a catfish and a shark. He has a very large body with a gigantic mouth and sharp teeth and a disproportionately small tail and fins. He also has a fin on his back and catfish-like whiskers. Old Toothy has been described by Sawyer as the "biggest, scareiest, toothiest thing in the lake."
Role in series
"Jaws of Old Toothy"
Old Toothy made his first episode appearance in "Jaws of Old Toothy," where he attempted to swipe one of his teeth back from Buttsquat after he stole the tooth from him. McGee, Gretchen, Squirt, and Sawyer soon team up with Old Toothy to get the tooth from Buttsquat.
Old Toothy actually first appeared in the theme song, just about to eat the campers before Slimey saves them.
