Finn and Jake travel to a land where reality has been redesigned and improved.
Tropes:
- Anti-Escapism Aesop: Jake insists living in VR is bad, and even destroys the machine everyone is using, but he's really oversimplifying things. As pathetic as the humans on the island are, they really can't live much any other way, and BMO defends their world as no less real than any other. BMO still decides to leave after rebuilding, but mostly because they would miss Finn and Jake.
- Chest Burster: Jake wraps his body around a giant egg, and when the bird inside hatches its beak pokes out of Jake's chest.
- Cyber Space: The humans of this island wear VR gear at all times while robots take care of their physical needs.
- Everything Is Online: The VR world is hooked up to an "island chain brain frame" that tells everything about the islands, and instantly finds Susan.
- Eyepatch of Power: BMO's avatar is a giant muscular figure wearing eyepatches on their arm and legs.
- Fantastic Slur: The people use "system dump" as an insult to call someone a loser or weirdo.
- Future Slang: The people in VR have developed an exaggerated version of internet slang that's nearly incomprehensible.
- Like a Duck Takes to Water: BMO immediately takes to the VR world, becoming a well-respected moderator and designer.
- Non-Human Head: BMO's avatar is a giant humanoid with their real-world body for a head.
- Reactive Continuous Scream: Jake and Finn create their VR profiles while screaming in shock as being in the system, resulting in them both having "AHHHHH!" for a username and random crap for an avatar.
- Simulated Fantasy, Post-Apocalyptic Reality: Jake, Finn, and BMO end up on a lost colony of humans who have survived the Great Mushroom War where all the citizens have become hopelessly addicted to virtual reality, leaving the entire city and their basic needs to be taken care of by robot drones. Jake "unplugs" everyone, only for them to find that the human population has become so used to living in Cyberspace that they have no clue how to function in reality.
- Stating the Simple Solution: Jake says they can take just BMO out of the VR by force, but gets an electroshock when he tries to take the headset off. Then he just shuts the system down, releasing everybody.
- The Tetris Effect: The humans forced out of VR don't understand that "get x" console commands don't work in real life.
