Reward Challenge: Survivor Auction

Immunity Challenge: Back Splash Each person have to balance on a very small perch, while leaning back holding onto a rope. Every five minutes, they will move further down the rope, which makes it more difficult. When they cannot hold on any longer, they will drop in the water and be out of the challenge. The last person left standing wins immunity.
