'My old friend Creepella von Cacklefur invited me to her family's spooky castle. And before I could say 'not for all the cheese in Cheddarton,' she'd mousenapped me! And holey cheese, what an adventure! I was off to Niagara Falls on a field trip with my nephew Benjamin's class. I was surrounded by mischievous young mouselets who seemed determined to send me over the Falls in a barrel!' —Geronimo Stilton
