In common with previous Simpsons Halloween specials, the episode is made up of three self-contained stories. The three segments which make up the program are "Attack of the 50-Foot Eyesores", "Nightmare on Evergreen Terrace" and "Homer3". The title of the first segment is a reference to the 1958 science fiction movie Attack of the 50 Foot Woman. The second segment is a parody of the 1984 horror movie A Nightmare on Elm Street and its sequels, and features the Simpsons regular character Groundskeeper Willie as a Freddy Krueger-like killer. The third segment, in which 2D cartoon character Homer Simpson enters a 3D world, is primarily based on "Little Girl Lost", a 1962 episode of the TV series the Twilight Zone, in which a girl enters a fourth dimension.
