Meanwhile, the knowledge that the tooth fairy is not real prompts Kyle to question the truth of all things, including his own existence.
The American Dental Association is suspicious about the missing teeth and money, and the leader (Dr. Roberts) concludes that the culprit is a giant half chicken, half squirrel that steals either teeth or money from children as they sleep in order to build some kind of giant nest for its genetically superior and potentially dangerous offspring.
Another dentist, Dr. Foley, logically concludes that the missing teeth and money are due to a black-market tooth racket that he has seen before in Montreal.
The boys are now rather wealthy from the tooth racket, but Cartman persuades them to cut their ties to Loogie and make more profits.
The local TV news reports a story about a child, Billy, who needs $600 for a bone marrow transplant, and has recently lost a tooth, but his parents plan to leave him the money.
Kyle, meanwhile, disappears while questioning his own existence, but soon reappears wielding control over all reality, even becoming the half-chicken half-squirrel beast, scaring both Loogie's gang and the ADA away.
As the credits roll, Kenny who is still attached to his concrete shoes, slowly hops through the shallow river and then falls into a deep spot.
Two other exceptions are "Trapped in the Closet" and "Cupid Ye", where the writing and directing was credited to John Smith and Matt Stone as a joke tying into the episodes.
