One of the "rides" at HorrorLand involves the characters being sealed in floating coffins, which either fill with insects or are closed so tight that the ensuing panic makes them feels like insects are crawling on them. Notably, this is the ride that finally breaks Luke out of enjoying the park.
The episode contains examples of:
The Morrises encounter a Horror carrying the decapitated head of a girl, which can still talk. The head tries to warn them to stay off the guillotine ride. Mr. Morris laughs it all off as special effects, but you never know…
The Morris family and Clay come across the clothing and belongings of the last family who made an appearance on Raw Deal.
