A colored grid floats out in the water, and we see shots of yellow rocks on the ocean floor. Peachy greets the S7 and calls the challenge "an island version of musical chairs." In the first round, they will all swim down at once to retrieve one of six shells -- marked by yellow rocks for visibility -- scattered along the bottom. Whoever comes back without a shell is eliminated. The S7 will repeat the process until only four of the competitors remain. At that point, the final four will "engage in" a sprint from the floating dock to the shore while carrying the yellow, forty-pound rock. Peachy says, "The first one to drop the rock at my feet wins the reward." Do they get extra points for kissing his feet once they've dropped the rock there? Peachy takes great pleasure in, once again, revealing his "personal Visa," which he will loan the winner for one night. He/she will use the Visa card to book a room on a luxury cruise ship...but why does the winner need the Visa if he/she don't get any choice as to the purchase? Shouldn't all of the rewards, then, have been collected using Peachy's Visa? Peachy dramatically says, "That cruise ship, right out there!" and they all turn around and act surprised that the big boat has suddenly materialized behind them; it blows its happy little horn in greeting. Or maybe it just blows. Anyway, Peachy says that the winner will board and check in. He "imagines" that he/she will then want to take a shower, and I suspect he imagines that in more detail for some members of the S7 than for others. The winner will also get a change of clothes -- his/her first in twenty-eight days, Peachy says, although Robert appears to be wearing new clothes today -- and a multi-course meal on one of the observation decks. The S7 are sent out to the floating grid, and Peachy explains the challenge again, in case their attention spans are really that short.
The race begins. Kathy starts out with one of her spectacular belly flops, causing much happiness among the crowd with whom I watch the show. We just wait for those. Paschal brings up the first shell, and Robert quickly follows; then Tammy, then Kathy. It's pretty clear at this point that these will be the final four in this challenge, since they're so clearly more skilled than the others. Vecepia just gives up and swims back to the grid; surprisingly, Peachy doesn't harass her about it. Sean is having difficulties; Peachy calls him "baby" and yells at him to "let go of that buoy, swim over, find a shell, and get it!" I don't think Peachy gets that Sean knows what he's supposed to be doing, and that he's just having difficulties physically doing it. Neleh and her baggy-panted bathing suit finally come up with a shell; Sean, after a great deal of effort, manages to get one, too. Peachy whispers to the waiting tribe members, "Sean may have one!" When Sean emerges a shell-bearing victor, they all cheer him on and seem genuinely happy for him. But then, he's just proved he's no competition in future rounds, so why shouldn't they be pleased? Peachy rubs it in: "Now you've just gotta do it again!" Peachy sends Vecepia back to the beach, and are these people the worst swimmers ever, or what? I don't even know if what they're doing could technically be called "swimming."
