Sea Monster Surprise (Geronimo Stilton Cavemice #11)

Bart Barnacle is ready to go home to the Land of the Rising Sun now that his giant pirate ship is finished, but he bursts into tears when he thinks of leaving his friends. He invites them all to come with him, but many have other plans. The Stiltonoots are always up for adventure, though, so when Geronimo inadvertently volunteers to go, Thea, Benjamin and Clarissa want to go as well. Packing up the ship takes a while, and the journey doesn't go smoothly-- a giant octosaurus attacks the ship and it takes the bravery of all on board to survive. When they finally arrive at Black Rock Island, Trap is accused of stealing food, and Geronimo must prove that his friend is innocent before the cavemice can head back home.
