Fort Boyard - Ocean Plunge

Two contestants, one male and one female, zip-line down from the top of the Fort's bastions into the sea. One of them, usually the female, then swims to the pontoon, whilst the other has to swim over to a buoy, where he dives down deep to reach the lobster pot. Once he has it, he swims over to the pontoon where the second contestant opens the lobster pot, takes out a key and opens a box which contains the clue word. Once they have it they shout it out to their team using a megaphone. There have been a few variations to this, where the second player swims to a boat as opposed to the lobster pot. Once there, one of the pair needs to climb a ladder to reach the numbers for the other person to shout back to their team for the clue.
