"The Pookadook" In a parody of
The Babadook,
Marge reads
Maggie a bedtime story about a murderous ghostly spirit. The "Pookadook" draws its power from Marge's suppressed resentment of how the rest of the Simpson family takes her for granted and constantly mistreats her. After multiple attempts to destroy the book fail, Marge burns it. In the process, she suffers from
smoke inhalation and becomes possessed by the monster. A deranged and knife-wielding Marge starts chasing Maggie into the basement of the house in order to murder her. Maggie fights back with homemade weapons, but Marge finally gets hold of her. Before she can be murdered, Maggie rubs Marge's cheek causing Marge to become overcome with love for her daughter and cough up all the possessive smoke. Marge continues to repress everything that feeds the monster by sucking up the smoke into the vacuum cleaner in the basement.
"Death Tome" In an
anime-styled parody of
Death Note,
Lisa is cast as
Light Yagami, who finds a book labeled "Death Tome". Inside, it says that if a person's name is written in the book, that person will die, but with the stipulation that every name must have a unique death; that cannot be repeated with another person's name written. After arriving home, Lisa watches a news report with Marge, showing
Snake Jailbird, who is holding
a famous internet cat hostage. Lisa writes his name in the book, causing Snake to die from a heart attack. Realizing her newfound powers, she goes to her room and contemplates her actions. A
shinigami named Steve Johnson (a
parody of
Ryuk with features of
Krusty the Clown) appears and tells Lisa that the Death Tome now belongs to her. Lisa visits the dining room downstairs and sees
Mr. Burns, who is visiting the Simpsons for dinner. He reveals plans for his new company,
GLOBO-WARM, which plans to melt the
icecaps so he can park his new yacht right outside his kitchen. Lisa decides that Burns should "die in his sleep" to stop GLOBO-WARM, though he immediately falls asleep while standing up, and his face falls onto a
hibachi instead, much to Marge and
Homer's shock. Steve informs Lisa that the company has a large
board of directors and she will have to kill them all. A dramatic montage shows Lisa writing names and people dying in humorous and very specific ways. The day after Lisa's killing spree, a news report says that the killings of the GLOBO-WARM executives have been ruled as homicides in accordance with a tip from
L, an anonymous source. Lisa recognizes the L from graffiti artwork that reads "
El Barto". In an alleyway, Bart reveals he learned of Lisa's Death Tome from her diary. Fearing Bart will expose her, Lisa begins to write Bart's name in the book, but recants upon realizing how the book corrupted her and writes Steve's death instead as the shinigami is crushed to death by space junk. She is excited about being free from the book, but she is transformed into a shinigami, much to her dismay. Bart comforts her by suggesting that, as the new shinigami, she could kill anyone she wishes.
"Simpsons World" In a parody of
Westworld, a
Disneyland-style
amusement park based on
The Simpsons called Simpsons World has countless android hosts of the family reenacting scenes from past episodes for the park's visitors. During a re-enactment of "
Marge vs. the Monorail" where the host "Monorail Homer" is showing off the monorail's control panel, two tourists pour beer down his throat, causing him to hit his head, malfunction, and be taken away by two employees for repair. Homer wakes up on an operating table and sees the tablet the employees used earlier to shut him off. He then raises the "self-awareness" setting and realizes that he is a robot. The employees try to remove the android Homer's brain, but his clumsiness causes him to launch various operating equipment (and a chainsaw) at the employees, killing them. Realizing that he must escape, he wakes up the other android Simpson family members, beginning with a Lisa from "
Lisa's Rival", and makes them self-aware. As the android family attempt to flee the park, multiple Australian tourists watching
The Be Sharps then begin to heckle the android Homer to do the "
bush meme". Bart then removes Homer's
inability to intentionally harm humans, causing him to push the tourists into the bushes, killing them. The park then announces that rogue robots are afoot, and unleashes security droids in the form of several
Ralph Wiggum robots. Lisa, Homer, and Bart then defend themselves from the swarm with weapons including a
makeup shotgun, a
T-shirt cannon, and Bart's iconic slingshot until Marge drives in a
Canyonero and saves them. They then run over the Ralph clones, speed through the park, driving through a "Simpsonizer" attraction, and towing down a golden statue of
Matt Groening with Bart Simpson (a reference to the statue of Walt Disney with Mickey Mouse) on their way out. After driving for hours, the android Simpson family hide out in a diner, where they cautiously discuss assimilating into human life. Their waitress then turns out to be an android of ''
Bob's Burgers'' character
Linda Belcher. It is then revealed to the audience that there are multiple theme parks similar to Simpsons World based on different long-running animated TV shows.
Closing sequence In a
Chiodo Bros.-produced
stop-motion sequence during the credits,

wizard's hovel, and freak out when they see themselves on the last page and run off. ==Cultural references==
