The gang then heads to a local restuarant to meet Captain Morgan, their tour guide for Skull Island. The island used to hold a prison for the most dangerous criminals, but has been turned into a tourist attraction. The gang is discussing the man in the iron mask, when Mama Mione, the owner of the restaurant, begins telling them the story of Old Iron Face. She claims he is the one who haunts Skull Island after being a prisoner there years before. He wore the iron mask so no one would have to look at him. (The Creepy Case of Old Iron Face)
