Synopsis[edit]

"In the opening sequence, Maggie is born, and she's evil. In "Danger Things", Milhouse gets lost in another dimension and it's up to Lisa to save him. In "Heaven Swipes Right", after death, Homer gets sent back to Earth in various different bodies as he died before his time. Finally, in "When Hairy Met Slimy", Selma finally finds love in an unlikely place—the alien in the basement of the Power Plant."


Plot[edit]

Opening sequence[edit]

It's Halloween, and Marge is giving birth to a new baby when an unexpected boy emerges from her womb. Homer is terrified at the prospect of a second Bart, who is completing graffiti on a wall to say "boner", so he asks Dr. Hibbert to change the baby. Hibbert gives them Maggie, but warns that "she tested positive for evil".

Maggie demonstrates her powers by choking Hibbert, placing him in the baby incubator, and raising the temperature to 1,800 °F, incinerating him. They take her home, where she makes the toys' heads twist until all the fluff bursts out, burns the posters Homer puts on the wall, and eats and spits a bird in his face. Homer begins to ponder if it was the right decision.

At her birthday party, she burns Gerald's unibrow and causes Kearney, Shauna, and Dolph to hang themselves from a window. Ned decides it's time to stop her, especially after she turns Rod and Todd into bad boys, saying he'll perform three funerals that night.

At the cathedral, Ned is stopped by Marge, but he warns them she's bearing the mark of the Beast, Mickey Mouse, before correcting himself to the number of the Beast, 666. After not being able to kill her, she destroys the cathedral ceiling and impales Homer, Marge, and Ned.

Danger Things[edit]

In the 1980s, in Bart's treehouse, Bart is playing E.T. with Martin, Milhouse, and Nelson. After getting a game over, the kids split up to ride home on their bikes, and Milhouse gets attacked.

Luann and Kirk worry when Milhouse doesn't return, and Kirk starts breaking through a wall trying to find him. The police find his bike near the woods, while Kirk places letters on the wall to see if Milhouse is in another dimension and can communicate with them.

With Milhouse missing, Luann confesses she's having an affair, and Disco Stu comes downstairs, revealing it's him. Milhouse sends an SOS using the letters, but due to their issues, they send him and his lights up to his room.

At the Simpsons' home, Lisa gets a call from Milhouse, but when she says she doesn't like him romantically, he hangs up. Lisa visits the Starcourt Mall, whose sign becomes the Ratscourt Mall as rats swarm it. At the arcade, she informs the kids Milhouse is trapped in another dimension, and he calls out from the video game Bart was playing.

They go to Professor Frink's lab to find a way in, and Lisa uses a sensory deprivation tank to locate Milhouse. In the Over Under, Lisa finds Milhouse, but they're spotted by Demogorgons, who bite off his left leg when he doesn't stop talking.

They try to escape the Demogorgons in town, as other monsters devastate the city. Lisa reveals she has psychic powers, but they're trapped until Homer saves them with a flamethrower, revealing Mr. Burns opened the portal to find monsters for a secret government project. Homer tells them they're all trapped in the dimension, so they sit on the couch before discovering a Demogorgon version of Ned, whom Homer burns.

Heaven Swipes Right[edit]

At the Springfield Atoms Stadium, Homer, Moe, Lenny, and Carl are watching the Springfield Atoms vs. Shelbyville Shelbyvillians game, when a hot dog chokes Homer to death as the crowd shouts "choke".

In Heaven, he meets St. Greeter, who welcomes him with a pun on his name. Homer doesn't forgive the pun, so he gets damned to Hell. He finds out God sold Heaven to Google and learns he died before his time. However, he can't return to his body due to its decay.

Homer is given the chance to live as a man destined to die that day, and he chooses Atoms' quarterback Case Diggs. Marge loves the new body, but Homer ruins it in one night by overeating. Bart and Marge convince him to try Superintendent Chalmers' body next.

At school, Homer makes Skinner give Bart all As and twist his nipple until it's deep purple, then visits Chalmers' home only to learn he makes very little money. Homer changes bodies again, but Marge has had enough. Homer decides to settle on one body—the man who loves her as much as he does—Moe. However, Moe finds himself in Maggie's body and informs her he's thirsty.

When Hairy Met Slimy[edit]

At the Power Plant, Selma sneaks through a maximum security door to smoke and finds herself in a laboratory, where she meets Kang and they fall in love. When Kang offers the secret to clean, natural energy, Mr. Burns wants to dissect him, so they flee to a distant galaxy with Homer's help.

Selma and Homer sneak Kang out in a rat-filled waste container, but Burns finds them. Kang bites off Smithers' head and knocks out Burns, while Barney drives the trio away. Mr. Burns and the military pursue them, but the driver is shot as they head toward Mt. Springfield. Just as they think they're safe, Kodos arrives in a ship, but a shootout leaves Selma wounded in the stomach.

Kang uses Thanos' infinity gauntlet to eliminate the military, and when Burns survives, he hits him with a tin can. Kang heals Selma and reveals he's pregnant.

Patty protests their differences, citing zodiac signs, but Kang points out he's from Sagittarius. Patty begs Selma not to go but falls in love with Kodos. They fly into space and arrive on the honeymoon planet, in the cool season, where it's 4,000 °F.
