My autosaurus will win!

"Geronimo Stiltonoot is competing in a race to Boulder Bay and back! It will supply the village cheese maker with rare hot lava peppers, and there's a big prize for the winner. Unfortunately, Geronimo has a lazy, slow, city autosaurus (the cavemice mode of transportation). Can he reach the finish line without going extinct on the way?"--Page 4 of cover.
