The members of Soliantu arrive at the challenge. While the soundtrack chants, we see nine colorful, lettered blocks, and a clump of colored coconuts falls to ground. Peachy reclaims the immunity necklace from Kathy, and explains that today's immunity challenge will consist of a series of questions about life and survival on the Marquesas Islands. Each of the S9 has a station with three coconut clusters strung up at the top of a coconut tree. I'm amazed -- based on the usual logic of this show -- that they are coconuts attached to a coconut tree, instead of mangos strung up on a coconut tree, or coconuts strung up on a banana tree. Or even little shrunken heads strung up on a lollipop tree. In any case, every time members of the S9 answer a question correctly, they get to chop down a competitor's clump of coconuts, and the last person left with any of their three coconut clumps remaining, wins. Peachy explains that if they all answer correctly, then they all get a turn to chop. I'd like to point out at this point that they really, really, really need those big, stupid colored blocks to express their answers. The producers of this show welcome any chance they get to create more "authentic" props that they can later auction off on eBay. At least Peachy didn't say, "Your colored, lettered blocks are just like those used by ancient Marquesan tribesmen to determine which member of the tribe to eat next."

But onto the questions. True or false: drinking large quantities of coconut milk helps combat dehydration. False, sillies! It has a "laxative effect," and Sean, Tammy, and Robert all get it right. They pull little tiki figures from a basket to determine the order in which they'll cut down their tribemates' coconuts. Sean makes a fuss over eliminating one of John's coconut bundles, and John tries to act like he has a sense of humor about it, exclaiming, "Surprise, surprise! Shock of all shocks!" Zoe congratulates Sean on his "good form." Robert says, "Go Rocky!" as Tammy takes out Sean's first bunch of coconuts, and Sean says he "see[s] what's going on." Robert takes out Sean's second bundle of coconuts, prompting Peachy to declare Sean a "marked man."

On to the second question. Cannibalism was common in the Marquesas for which of the following reasons: (a) as a means of purging the sins of the tribe; (b) as a protein source; (c) for tribal sacrifice; or (d) to "seize the power of the person being eaten." It's all about the power seizing, and John, Vee, Zoe, Sean, and Neleh all agree. Vee loves Kathy but takes down her coconuts because Kathy's on a roll; she insists that it's "no hard feelings, though." Sean takes out John's second bunch. Zoe jokes that it was a tough choice, and insists, "Payback's a bitch," as John's turn is next. He determinedly struts past Sean and blows him a kiss. Actually, he desperately tries to blow Sean a kiss, but he can't catch his attention, so then he has to whiningly call for him, and it loses its effect. Still, Sean pretends to catch the kiss and then slap it on his ass. Hee. Vee looks kind of sad. John skittishly chops down Sean's last bunch, so Sean heads off to the sidelines. Neleh is next, and she gleefully takes out Vee, which causes Robert to exclaim, "You're really crackin' some nuts." Zoe also takes out a Vee bundle, and Sean proclaims it a conspiracy. Sean threatens to call Johnnie Cochran "if somebody hit[s] Vee."
