find Dr. Hibbert running the island's resort after hearing rumors he has gone mad. The family has dinner with Professor Frink, who is transformed into a turkey as the main course. When Marge explores the island, she is captured by Hibbert, who transforms her into a blue panther. She returns to her room and has violent, animal sex with Homer, who belatedly realizes that she has been mutated. Homer treks across the island looking for a cure to Marge's condition, but encounters Ned Flanders, who is now a cow-human hybrid in need of a milking. After Homer reluctantly milks him, Ned takes him to meet other Springfield inhabitants who have also been turned into mutant animals, including Bart (now a spider), Lisa (now an eagle) and Maggie (now an anteater, who is nearly eaten by Lisa until Homer intervenes). Homer, initially appalled at what everyone has become, eventually embraces the concept of being a mutant animal upon realizing how well it fits in with his personal lifestyle. The segment ends with a mutated Homer in the form of a walrus and the rest of the Simpsons and Springfield mutants lounging aside the resort's pool, intending to spend the rest of their days on Hibbert's resort. Ending The episode concludes with an appearance by Kang and Kodos, observing that Hibbert's skull-shaped island resembles their alien number 4. Production This is the first "Treehouse of Horror" special to be called "Treehouse of Horror" instead of "The Simpsons Halloween Special" in the opening or title sequence. This is also the first "Treehouse of Horror" episode to use the digital ink and paint as a proof of concept, and the fourth Simpsons episode to be done in the process following "Radioactive Man", "The Simpsons 138th Episode Spectacular", and "Tennis the Menace", which led to the decision to have The Simpsons' animation converted from traditional cel to digital ink and paint. It was a good episode to test technique on due to the cloning sequences which required many different layers of animation for each of the clones. According to Al Jean, in the dub for the scene where Homer is being cloned, Matt Groening said "let's just throw a couple screams in there", and sound archive locator Norm supplied them. The effect coming out of the hammock is meant to resemble a Xerox light. This was one of two years that did not feature special
