40 free Geronimo Stilton trivia questions with answers — literature quiz, new questions added Oct 2026.
Geronimo Stilton is a mouse who would much rather stay home with a good book than go anywhere dangerous, which is exactly why his adventures are so funny. He runs a newspaper, narrates his own stories, and is forever being hauled off to jungles, haunted castles and frozen peaks by relatives who are braver than he is. More than 300 books later, he is one of the best-loved characters in children's fiction. This quiz covers the whole world of the series. There are questions on the family, friends and rivals; on the individual books readers ask about most, including I'm Too Fond of My Fur!, The Mummy with No Name, The Secret of Cacklefur Castle, The Fast and the Frozen, Alien Escape and The Dragon of Fortune; and on the spin-off series set in prehistory, in outer space and in a land of fairies and dragons. A few questions look behind the pages at how the stories began and at the comics, games and animated series they inspired. It is written for young readers and for the parents, teachers and librarians who read along with them. The first questions are the easiest, so a child who has read only a book or two can start strong, while the later ones will test true fans. Every answer comes with a short explanation.
