Help, I'm in Hot Lava!

It’s time for the Mouse Island Games—the biggest sports competition in the Stone Age! Geronimo Stiltonoot isn't exactly the athletic type, but he’s been recruited to compete. The stakes are high: the winner gets a trophy made of solid gold, but the loser has to take a dip in a pool of hot lava (okay, maybe it's just a very hot spring, but it feels like lava to Geronimo!). Between sabre-toothed tigers on the track and a volcano that looks ready to pop, Geronimo has to find a way to survive the games without getting singed.
