Russell becomes ecstatic as he reviews the plans for his first slumber party while with Blythe at the day camp. Jealous that they are not invited, Sunil and Vinnie make plans to crash their party. Meanwhile, Mrs. Twombly notices her supplies are being consumed by something, and jokingly cites a poltergeist as the cause of it, which awakens Russell's superstitions about a ghost he read up on. Later, Sunil and Vinnie's attempt by to break in to the pet shop sends the city without power, causing Russell to hallucinate an octopus-like creature trying to devour him.
