Jump on a log raft and head for Tom Sawyer Island, right in the middle of the Rivers of America! As soon as you and your fellow pioneers dock, your adventure begins. What does the single glowing lantern in the darkness of Injun Joe's Cave reveal? And what will you discover in Tom Sawyer's Treehouse, or from Castle Rock?

There are many exploration points on Tom Sawyer Island. A creaking and swaying suspension bridge and pontoon bridge, a cave where insect fossils and glowing stones lie... And when you're tired of exploring, take a break at Fort San Clemens. Huh? Who's that snoring really loudly?
