Rewards Challenge would see two members designated as swimmers. One at a time they will grab a club and swim out to a platform. Climbing onto the platform, they must leap off and smash a box in midair with the club to release a key. After retrieving the key the will swim back to shore and the next swimmer continues on, until all 6 keys are found. The keys will open a box and reveal puzzle pieces for others to put together. Winners receive potatoes and peanut butter. Immunity Challenge has each member assembling a stair case out of logs to reach the top of a tower. Once all members are on the tower, three will repel down a zip line and retrieve a bag of puzzle pieces from the water. Once back on the tower, the remaining three members will assemble the puzzle.
