The "Simpsonsworld" segment is full of references from throughout the series' history:
- The segment begins with a reenactment of "Marge vs. the Monorail", even down to reusing the original footage until two guests interrupt.
- When two obnoxious guests force feed Homer some Duff, he gets stuck in a catchphrase loop, saying such memorable lines as "Woohoo!", "Boring!", "Stupid Sexy Flanders!", "Why you little...!", "I am so smart!", "Where's my burrito?" and "I'm king of the world!"
- After breaking Monorail Homer, the tourists responsible declare they're going to go and shoot Mr. Burns next.
- At the beginning when the Homer robot is being taken in for repairs, the engineers drive past Grampa yelling at a cloud, Lisa riding her pony, the Old Simpson Farm, two Homers driving the Homer and the Mr. Plow truck, the Big Butt Skinner balloon, Kamp Krusty, Bart riding Stampy, Moe flying in the air with a beat-up Homer, Troy McClure's house for sale, Bart and friends dragging Nelson off in a wagon, Homer going after animate chocolate rabbits in the Land of Chocolate, Hank Scorpio using a flamethrower, and Lisa and "Bleeding Gums" Murphy playing their saxophones on a bridge.
- The engineers discuss that one of them went on a date with the Props Department person who is in charge of Sideshow Bob's rakes.
- Homer says "What the frosty chocolate milkshakes?" when he sees a robot Sideshow Mel being made, referencing one of his earliest catch phrases from The Tracey Ullman Show shorts.
- When Homer walks through the storage facility, he finds a bunch of broken Replicants of various Simpsons characters:
- Lenny with a spring in his eye
- Groundskeeper Willie with a dolphin gored through his chest
- Lance Murdock after his stunt went horribly wrong
- Scratchy skinned and his eyeballs in his mouth
- Frank Grimes (possibly after getting fatally electrocuted)
- Rainier Wolfcastle wearing goggles and slightly dissolved
- The Grumple with green fluids coming out of his orifices
- He then encounters the storage facilities containing variants of his family members:
- Marge:
- Bart:
- Lisa:
- Florida Lisa
- The Lizard Queen
- Cool Lisa
- Hipster Lisa
- Pony-Riding Lisa
- "Ravencrow Neversmiles"
- Lisa The Beauty Queen
- Future Wedding Lisa
- Hockey Lisa
- Lisa with Braces
- Class President Lisa
- Frida Kahlo Lisa
- Lisa with Bubble Gum, Peanut Butter, and Mayonnaise on her head
- Lisa the Clown
- The Lisa Homer ultimately chooses to reactivate talks about working on a diorama of ''The Tell-Tale Heart''.
- Grampa:
- Later, a crowd of Homer robots can be seen walking in a group, some of them based on specific appearances:
- Pyro can be seen running in the MegaGlobe.
- At one point, the flying pig from Lisa the Vegetarian can be seen soaring through the sky.
- Stupid Sexy Flanders can be seen posing for some guests.
- When the Simpsons try to escape the park, they go past the Aztec Theater playing The Itchy & Scratchy Movie, Poochie and Roy walking by, Springfield's lemon tree, Marge in police attire arresting Fat Tony and other members of the Springfield Mob, and Homer, Barney, Skinner and Apu singing atop Moe's Tavern.
- In the background of some shots you can see not only mainstays of Springfield like the Android's Dungeon and Moe's Tavern, but locations that only appeared once like Maison Derrière and Mr. Burns' Casino.
- Two guests force Homer to do the "backing away into a hedge" meme until Bart deactivates the protocol that prevents the hosts from hurting humans, at which Homer declares he's sick of that joke and forces them to do it instead, killing them.
- One of the group who was standing and watching all that unfold was holding a cup of Flaming Moe.
- A Marge is seen operating a pretzel stand, next to a guy operating a Khlav Kalash stand.
- A Homer trying (and failing) to jump Springfield Gorge can be seen in the background as the guests start panicking.
- The Ralph army can be a reference to Holidays of Future Passed where Future!Ralph is cloned multiple times to perform a variety of odd jobs. Two of which worked as police officers.
- The Ralph robots recite the "My cat's breath smells like cat food" and "I choo-choo choose you [to die]!" lines from "Lisa's Rival" and "I Love Lisa" respectively.
- One of the Ralph robots has the Leprechaun sitting on his shoulder.
- To fend off the Ralphs, Lisa takes a Whacking Day bat and starts swinging at them.
- Homer topples another Homer chained to the Stone of Triumph onto the Ralphs, complete with the Stonecutter building and Number One standing next to him.
- Marge and Maggie tip an angel's rock-embedded skeleton onto the Ralphs to crush them.
- Bart uses multiple megaphones to create a shockwave that destroys many of the Ralphs.
- Lisa shoots one of the Ralph robots with the make up gun that was set to 'whore'.
- Homer fires a T-shirt cannon at Ralph robots, and ends up hitting a Maude Flanders robot, exactly like what caused her death in "Alone Again, Natura-Diddily".
- A Homer and Marge can be seen nude in a hot air balloon along with the Escalator to Nowhere.
- The family escapes the park in Marge's F-Series Canyonero, complete with a snippet of the commercial jingle.
- A guest can be seen wearing Homer's conspicuous camera hat.
