The Tooth King appears only as a stop-motion character in the episode " The Lollistops" . He rules over the Toothporium, and asks for $4,000,000 for a large jar of teeth.
The Tooth King is a deep-voiced set of teeth, gums, and eyes, resembling a chattering tooth toy. He talks by moving his upper jaw up and down. He holds a rod with a tooth on top, and a crown is floating above his head
