Survivor: Panama
Immunity Challenge: Beginning on platforms in the ocean, the tribes must race over a wall, dive into the ocean and swim to their tribe raft. The last person over the wall dives down to unclip a rope underwater, letting the raft loose. The tribe then paddles the raft towards shore. Once the tribe hooks their raft to the post on shore, they race to solve a puzzle, which lets a giant ring loose. The tribe has the choice to dig down many feet and look for an answer key to solve the puzzle. Once the ring is let loose, the tribe attaches it to a rope that they use to throw at a hook to raise their tribe flag. The first three tribes to raise their flags win Immunity.
