The Simpsons go to a crappy theme park (like they did in "Itchy and Scratchy Land") that has one good ride: a rocket ship that blasts the family off to space and onto Kang and Kodos' home planet (again) (cf. "Treehouse of Horror I").note
- Are We There Yet?: Bart and Lisa keep annoying Homer with this question while he drives them to the theme park.
- Continuity Nod: While in a spaceship with no gravity, Homer tries to eat floating potato chips the same way he did in Deep Space Homer and the scene even has the same background music from then. This time, however, other characters snatch the chips as soon as Homer tries to eat them.
- Corrupt Corporate Executive: Whoever built Dizzneeland is clearly only interested in money. For one thing, outside baby pacifiers are banned, and families are forced to rent pacifiers for $25. They also kill guests who stay in misting stations for too long, and resell their hats. At one point, there's even a plane with a banner ordering guests to continue spending money.
- Did Not Think This Through: It's only after the Queen eats a piece of Homer that her subjects bother to completely check if humans are really edible for their species—and because of Homer's (and, to a certain extent, the rest of the family's) general unhealthiness, the Queen ends up dying.
- Disproportionate Retribution: Staying in the Dizzneeland's misting station for too long results in the park owners switching it from water to acid, dissolving all patrons present except their souvenir hats, which are then resold.
- False Reassurance: After the Simpsons finally find a place to park their car, Homer says he'll write down the place where they park so they won't forget. He writes "Parking Lot."
- Leaning on the Fourth Wall / Medium Awareness: When Kang and Kodos (two characters more commonly associated with Treehouse of Horror) make their presence known, Homer responds that it isn't Halloweennote .
- Political Correctness Gone Mad: The park's pirate-themed ride is turned "politically correct" because of constant complaints from two people. It features a pirate being executed for being biased.
- Dizzneeland having bought the Cosmic Wars franchise is a reference to Disney buying the Star Wars franchise.
- The "ethnic Princess" featured in a poster looks like Princess Jasmine.
- The leadup to the ceremony where Homer is to be eaten takes a number of cues from The Hunger Games, with an announcer modeled after Caesar Flickerman and the Rigerian who takes out the tools (who describes himself as the kindest of them resembling Cinna.
- Take Me Instead: Since the resistance took Homer, the Rigerians said the rules meant that the rest of the family would be sacrificed. When Homer returned to turn himself in, he tauntingly asked what the rules said about that, with Kang answering that all the Simpsons would be sacrificed, much to Homer's chagrin.Lisa: You know, this system's rigged against us.
- Take That!: Dizzneeland is a grossly-exaggerated version of Disneyland (and Disney Theme Parks in general) in the mid-90s to early 2000s, when Paul Pressler and Cynthia Harriss were in charge of the park and essentially turned the park into a giant outdoor shopping mall.
