It's Halloween and Claire's throwing the biggest bash in Peaceful Pines until Lydia announces that she, too will throw a party. But when Delia's party ideas fall short, Beetlejuice introduces Peaceful Pines to "Party People in a Can".

Beetlejuice has a run-in with a newly-hatched Sandworm, and Lydia accidentally calls him out of the Neitherworld while he's in contact with it, so they both are brought to the Outerworld.

Beetlejuice's neighbors kick him out, so he tries to be a "good neighbor". But his idea of being a good neighbor is very different indeed.
