On Halloween, Carly, Freddie and Sam do a special webcast in apartment 13B, a supposedly haunted apartment. Numerous spooky things happen: lights fail, "blood" appears, objects fall and break, and the apartment owners return early. The apartment is later known to be an old apartment as the iCarly crew find that the doorman, Lewbert, had purposely given them wrong information. The owners give explanations of the happenings, and iCarly continues. Meanwhile, Spencer is making a giant jack-o-lantern and forgets to buy candy for trick-or-treaters. When he gives them ridiculous items such as a carton of eggs and jumper cables, they storm into the room, causing Spencer to hide in his monstrous jack-o-lantern. They roll him out to the hallway and out to the street, into the harbor where the pumpkin sunk. The episode ends with Spencer saying: "NEVER FORGET TO BUY CANDY ON HALLOWEEN".
