==Rules==
In , the castaways are divided into heats. In the first round, contestants race across a pontoon and dive into the water. Using a rope suspended beneath the platform, they pull themselves, underwater, to the other end. Upon climbing back onto the platform they must jump back in the water and do it again. The first two contestants to complete two laps move on to the final heat. In the final heat, the castaway had to do five laps and upon surfacing, they must transfer a medallion from one side of the platform to another, one key at a time. The first person to transfer all their five keys to the other side of the platform wins immunity.
In , they do the same thing but move a ring from one end of the pontoon to the other. The first two contestants from each heat to move two rings move onto the final round, where five laps are undertaken. The first castaway to move all five rings wins the challenge.
