In "Survival of the Fattest", Mr. Burns invites many of the townspeople to go hunting, but Mr Burns plans hunting the townspeople. In the end Homer is the last one alive, but for how long?

Opening sequence[edit]

In the opening, using an accelerator-beam called the Accele-Ray, Kang and Kodos hope to speed up a World Series baseball game to air The Simpsons Halloween Special. Things later go sour when Kang makes the baseball game go too fast, causing the baseball stadium to be suck in to a specific point where the gravity is high. Afterwards the stadiums' surroundings are sucked into this point and then the whole city of Springfield, then Earth's oceans, the whole planet Earth, the solar system, the Milky Way, numerous galaxies and finally God is sucked into this singularity, a form of the Big Crunch. Kodos says to Kang, "Smooth move, space-lax! You've destroyed the totality of existence." Kang replies, "It will be fine. I'll just leave a note." The note is yellow and says: "Treehouse of Horror XVI" in blood.

B.I.: Bartificial Intelligence[edit]

Bart ends up in a coma after attempting to jump from the roof to the swimming pool at Spinster Arms Apartments. In an effort to cope with the loss of their boy, the family takes in a robotic boy, named David, who quickly proves to be a better son. Later, Bart is found to be alive, however the two boys soon try to compete for their families love. Marge grows concerned with the boys rivalry, Homer comforts her and says he'll fix it. Of course instead of getting rid of the better robot son Homer decides to dump Bart in the woods. Bart soon comes across a band of defunct robots, harvesting their parts to become a powerful cyborg, He returns home to seek his revenge on David, and in the end, he cuts both Homer and David in half. Eventually, Homer, who no longer has his legs, now has to be fused with David's legs. In the end it is revealed that it was all a dream induced by Homer's Demonic Possession, in a parody of 'The Exorcist'. A priest comes and splashes holy water on Homer who begins to perform the exorcist movements and music, and climbs up on the ceiling. Marge calls the plant to tell them that Homer won't be able to come in today, and Homer exclaims "Whoo-hoo!" and collapses on the bed, relaxed, but with his head still turned around backwards.

Survival of the Fattest[edit]

Survival of the Fattest TV Guide

Homer and other citizens of Springfield receive a letter from Mr. Burns to come to his mansion to go hunting. Homer goes, despite his family's warnings. Unbeknownst to them, they are the prey to be hunted by Burns. After his lawyer writes something that "should work in just about every courtroom" (and is then shot by Burns), he gives everyone five minutes advantage, but even so he manages to kill almost everyone, some of who climbed a tree but were launched into the air by Homer, and shot by Burns (except for Moe, who dies because of being splat by a dead Chief Wiggum). While the Simpson family watch the hunt on TV, the survivors hide in a forest, in which Professor Frink is eaten by Homer and everyone but him is shot by Burns' attack helicopter. Homer manages to survive the night as his friends are killed, and he uses Barney's dead body so Burns thinks he is Homer. He falls from a tree and Burns is ready to shoot at him, but just as he is about to do it, he and Smithers are both knocked out with frying pans by Marge, who then hits Homer for being away from home for eighteen hours and not calling. The segment ends with two reporters showing Homer and Marge making love behind them.

I've Grown a Costume on Your Face[edit]

Everyone as pacifiers

The citizens of Springfield dress in their Halloween costumes for a costume contest. A wicked Witch also entered, and won. But after revealing that she isn't wearing a costume, and is really a witch, she is disqualified and her prize is taken away. In revenge, she turns everyone into the actual characters that their costumes are. All of the citizens have problems with their appearances, including the Simpsons: Homer's head falls off, Marge turns into a skeleton (But with her own Human head), Bart into a werewolf, Lisa into Albert Einstein and Maggie into a witch (as they were all dressed like that). Lisa tries to discover how to reverse the spell, then she realizes Maggie is now a witch and she can do it. The citizens come to their house, some saying they like their appearance and abilities, and some saying they want to be back to normal. Maggie gets confused, so she eventually turns the people of Springfield into pacifiers with their normal heads and goes away on her broomstick. Moe then tells the audience he hopes they have enjoyed this episode as much as the Koreans doing the animation. Dennis Rodman (also as a pacifier) comes and says he is working off a speeding ticket. Maggie comes back and casts another spell and the credits appear, presumably changing everyone back to normal.
