In the lagoon near Old Mouse City, cave mice have discovered a giant oyster. It holds a pearl of megalithic proportions! Since the mice of the lagoon don't have the tools to fish the oyster out of the water, they call on Geronimo Stilton to help. Can figure out how to get the pearl before the saber-toothed tigers catch wind of it.
