I'd still argue that doesn't give much of an opportunity for anything to happen, outside of the interior portion having blacklight.
If they were to do Wolfman, they'd very easily be able to have it be themed to carriage rides in the forest fields of Transylvania. Have it inter-connect with the forest play-area, before diving into the showbuilding where you use projection mapping as The Wolfman carves into the trains, causing the damage. "Carriage rides through forests go wrong" feels on-point with Monsters, exceedingly so.
