A Cheese-Colored Camper is the 16# book of the Geronimo Stilton series.
Geronimo travels to Ratzikistan to publish a guide book.
My grandfather William Shortpaws, also known as Cheap Mouse Willy, was back at The Rodent's Gazette, and he was determined to torture me. He wanted to publish a guide book to Ratzikistan, the Siberia of Mouse Island. And he ordered me to go there to write it! But as you know, dear reader, I hate traveling!
