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.

Beetlejuice (disguised as Betty Juice), Lydia, Bertha and Prudence go camping in the Neitherwoods.
