The newspaper for Level 4
After Lisa returns home with Bart, Marge discovers that her son's mind has been completely fragmented. Distraught, Marge runs around town trying to find anyone who can help her cause. Eventually, she manages to pinpoint Bart's problem: the aliens' Buzz Cola. Despite his claim of an extraterrestrial source, Marge consults Apu to see if he knows where the soda is coming from. He is unable to answer, and in a fit of rage, Marge takes her already active annihilation of the soda into full throttle, destroying Cola Trucks as a result.
Level 4 is set at Evergreen Terrace again and reuses the map from Level 1 but with a few modifications, such as instead of taking place in the day, the level takes place at dusk, just before night-time. The gates to Mr. Burns' mansion have been opened allowing the player to gain access to the mansion. Also, the gate of the grey house facing the mansion has been opened and Buzz Cola glass appears right in front of the Burns' Mansion on top of the gates as well. The chess board behind the mansion has also become accessible via car now unlike in Level 1 whereas the area can only be accessed by-foot (with the exception of cheats/glitches). Behind the Simpsons' house, the window to Bart's bedroom has been opened, and the player can now enter Bart's bedroom, which includes a Character Costumes icon allowing the player to change clothes. Lastly, the tomacco field by the power plant has been imprinted with an image of Bart's head, causing most of the plants to disappear.
Level 4 shares the same normal music with Level 1.

- This is the only level of a couple of things:
- This is the only level in the game where a player isn't required to buy a car from a particular character in order to initiate a mission.
- This level, along with Level 3, are the only levels where Homer has no role in the main story. He only interacts with the player in the two levels as an optional driver for both the Family Sedan and the 70's Sports Car. However, he appears in the Simpsons' house eating slices of cheese in the kitchen, and is heard when Ned Flanders approaches the window.
- This is the only level where Hans Moleman has a story role.
