The Smelly Search (Geronimo Stilton Cavemice #13)

For Cavemouse Geronimo Stiltonoot, life is one prehistoric problem after another! Geronimo Stiltonoot and friends have been invited to participate in a Stone Age treasure hunt. How fun! There's one issue: it's been set up by Gossip Radio host Sally Rockmousen, Geronimo's rival. Is it some sort of trick? The hunt is full of difficult riddles and very stinky dinosaurs... but nothing will stop Geronimo's team!
