Here Be Monsters! An Adventure Involving Magic, Trolls, and Other Creatures; The Ratbridge Chronicles Volume 1 Chapter 20

Inside the Cheese Hall

• The Cheese Hall is a large, creepy building with multiple rooms. Arthur decides to check out one labeled "Keep Out" first (always a good place to start). There's a dark passageway, and a deep shaft from which emanates the smell of melted cheese.
• Next he tries the Laboratory. There are all kinds of inventions lying around, and he looks around until he sees another doorway, this one marked "Dungeon." That's his next stop.
