Where are the Trick or Treat Houses Located in FischFright 3?
All trick-or-treating houses are in the new event area called Caustic Hollow, accessible via the famous haunted ship, the Flying Dutchman. When you spawn in Mosewood, the starting island, turn right and head to the edge of the beach; the ship will be visible right away. Board it and speak to its captain; he will take you straight to Caustic Hollow. You can find the details about all of the houses below, along with instructions on how to locate them.
