The Island is a small island in an unknown area, where people who "know too much" are imprisoned by Number 2. Homer Simpson was sent here after his Mr. X website became successful and started spreading around gossip. People who are brought to The Island are given a number and are often surprised by gas and drugs that they put on various things, like a phone booth, croquet balls and food. If someone tries to escape, they are chased by a capture bubble, though it can be easily popped. When Homer escaped The Island thanks to Number 6, he and his family were gassed by a fake Santa's Little Helper and taken to the island, where they soon got used to the gas and drugs.
- The Island, its leader and prisoners are all a parody of the 1960s TV show, The Prisoner.
