The Morris family gets lost while looking for the zoo. On the way, they find themselves in Nightmaria, a land of living night horrors. There are almost no visitors, no telephones, and the attendants are dressed up as monsters. Looks like it's a lot of fun here. True, the “Deadly Descent” from the mountain is too dangerous. And the "Mirror Palace" generally discourages any desire to have fun. All the jokes in Horror Park are too sinister. They cross all sorts of boundaries.
