I was just minding my buiness at home when I got a telephone call from my uncle Samuel S. Stingysnout. He wanted to invite the entire Stilton family to creepy, farway Penny Pincher Castle for a big surprise. Moldy mozzarella - I'm not much of a traveling mouse, and i hate surprises. But Thea, Trap, and Benjamin were going, so i couldn't say no. I could tell this was going to be one super-spooky trip!
