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, this level takes place at night time. Also, the gates to Burns' mansion have been opened allowing the player to gain access to the mansion, also, a gate that leads to a yard with a swimming pool has been opened and Buzz Cola glass appears right in front of Burns' mansion gates. 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. 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 shop for costumes. 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 driving music with Level 1.
