Plot
The episode opens with a sleeping Owen, who is having a pleasant dream about being naked in a world of floating cheese and "doughnut-copters." Just as he reaches the highlight of his dream, he is awoken by Leshawna screaming at a passing helicopter, saying to keep it down. Owen thinks that he hears the doughnut-copter from his dream, much to the confusion of his fellow campers. Chris then appears in an airplane, and when he lands, he announces that the next challenge will be the "Tri-Armed Triathlon." This is a series of three challenges that will be performed by the campers in pairs, handcuffed together, similar to a three-legged race. The winning pair will earn invincibility. Chris also mentions the wimp key, a key that can open the handcuffs and is offered at several points during the challenges. Any team that uses the key is eliminated from the contest and thus cannot win invincibility, but they are excused from competing in the challenges. In the confessional, we find that Gwen is really irritated about the whole show, but mostly by Geoff's cheery attitude. Geoff is bummed out because most of the other campers are becoming so serious with the end of the season coming up, and Duncan says that Leshawna has been warming up to him.

In the main lodge, Leshawna and Duncan, Owen and Heather, and Gwen and Geoff are handcuffed together for the first challenge: an eat-off, with one team member force feeding the other. The eater must keep both arms behind their back, which leaves the feeder with only one arm to use. Leshawna and Duncan immediately start fighting over who feeds who, Geoff's easy going attitude continues to annoy Gwen, and Heather realizes that her arms are almost too short to reach the table when Owen puts his arms behind his back. The seemingly normal food is brought out, prompting Heather to note that the chicken is oddly green.

In an attempt to win the challenge, Leshawna stuffs Duncan's face, who, in between gulps, asks for her to slow down, but she ignores his plea. Gwen tries to get Geoff in a rhythm to speed up his eating, but he keeps stopping to comment on how good the food is. Owen's mouth is wide open, and Heather keeps dumping spoonfuls of food in, but he tells her to go faster. Eventually, Heather ditches the spoon and decides to play the game to Owen's strengths by picking up the whole tray, and slamming it into his face. Heather and Owen win the first challenge, and Heather commends Owen on great teamwork, until he reveals he needs to go to the bathroom, and is seen racing towards the washroom, farting up a storm, with Heather in tow. Before starting the next stage, the campers are given the option of using the wimp key. Duncan and Leshawna dare each other to take it, and Owen suggests that he and Heather use it since they don't really like each other, however, Heather shoots that idea down.

The next challenge is to go to the beach, take a canoe and paddle  to Boney Island, where they will find a package waiting for them. Duncan and Leshawna are still fighting, Heather keeps cheering on Owen as he pushes the boat into the water and Geoff further irritates Gwen by telling her a story about how he and his buddy Jay dug up their friend's lawn and planted it in their school's foyer. While on the water, Leshawna keeps pressing Duncan about him being a softy underneath, mentioning Courtney told her about DJ and Bunny. Duncan confesses his good deed and reveals that his dog, Petey, ran away when he was a kid, and he didn't want DJ to feel the same way. Owen is then seen talking about how no one listens to him, and Heather interrupts to say she doesn't care. She then sees the shoreline and the package.

Getting on shore first, Heather and Owen find a backpack and open it. Inside, they find the pieces of the tiki idol that Beth took from Boney Island in Up the Creek. Chris reveals that Beth never returned the doll, and instead broke it into pieces and flushed it down the septic tank, disgusting them that they used a bathroom that had the cursed idol in it. The next challenge is to take one of the pieces and return it to the Cave of Treacherous Terror as fast as possible, because the longer you hold onto the doll, the more you get cursed. As a final twist, the campers have to go piggyback.

Owen and Geoff pick up Heather and Gwen respectively, while Duncan and Leshawna get into a fight over Leshawna's weight. After a while, Geoff and Gwen stop when she thinks they're lost; while Gwen tries to gain her bearings, Geoff starts taking pictures of the surrounding woods. This pushes Gwen over the edge, and she grabs the camera and throws it into a nearby pond, then starts demanding Geoff to take things more seriously, and to stop pretending to be her friend. Geoff counters saying that he wasn't pretending, and that he genuinely wanted to be her friend and that if they went to the same school, he'd certainly invite her to his parties, except that he thought she'd never want to go. Gwen reveals that there were times she wishes she was a bubbly popular girl that went to parties, but in the end, just doesn't think she has partying in her DNA. Geoff tells her that there's no party DNA, as partying is a state of mind, and invites her to a party when they both leave the island.

At the cave, Owen and Heather are the first to arrive, but there is a large spider in the entrance, and when it lands on Owen's face, he panics and runs away, taking Heather with him. Leshawna, carrying Duncan, arrives to see Owen and Heather hightailing it out of there. When they get to the cave, they have their own encounter with the carnivorous beavers and also run away. Geoff and Gwen arrive last, and Gwen thinks they've already lost, but Geoff thinks they're still in it and throws the tiki piece into the cave, winning the challenge.

The campers regroup around three picnic tables, and Chris updates the score, one point for Heather and Owen, one point of Geoff and Gwen, and nothing for Duncan and Leshawna. Chris then goes to one of the tables and lifts off the cover, revealing wooden heads of the losers, frightening Owen. The last challenge is to build a totem pole out of the heads in the order that the campers were voted off, which Chris listed at the beginning of the episode, with Ezekiel on bottom, and Izzy on top. Since Eva and Izzy were voted off twice, they have two wooden heads

Heather badmouths the losers as she picks up their heads, starting with Lindsay and Beth by calling them traitors, while Owen makes more statements about how hot Justin looks. Geoff and Gwen are trying to put the totem together, but have trouble telling the difference between Katie and Sadie. Chris checks in on Duncan and Leshawna and sees that Duncan has carved "D+C" in a big heart on the back of the Courtney head. Chris teases Duncan until Leshawna steps in and nails him with a Sadie head in Duncan's defense. Heather continues to disparage the losers and picks up one of the Izzy heads, repeatedly insulting her despite Owen telling her to stop. Her taunting eventually drives Owen over the edge, and he drags her along, insisting that he needs the wimp key. However, Duncan and Leshawna have completed their totem pole and ended the challenge. With all three teams tied, none of the campers gets invincibility.

At the campfire ceremony, Chris hands out marshmallows to Leshawna, Duncan, Heather, and Owen. With Geoff and Gwen left, Gwen believes her time is up and concedes defeat, but Chris tells her to sit down, and then gives her the last marshmallow. Gwen is shocked that Geoff is voted off, as he is the nicest guy there, but Duncan, Owen, and Heather reveal that's exactly why he has to go. Being popular with the others, if Geoff made it to the finale, their lack of popularity would help Geoff win, so he has to go. Geoff accepts his fate, and heads for the Dock of Shame.

On the way, Gwen stops him and gives him back his camera, which she fished out of the pond on Boney Island. Gwen is about to say goodbye when Geoff grabs her and takes a picture of them, complete with a small fish and water in the image.

General

 * At the beginning of this episode, Chris mentions the names of all the campers who have been voted off thus far, followed by a brief appearance in a flashback.
 * As of Geoff's elimination, Duncan is the only Killer Bass member left. Additionally, all of the remaining contestants qualified for the next two seasons.
 * No one wins invincibility in this episode, as each team won one round in the competition. This would be the case in a challenge later in the series, in This Is The Pits!.
 * This makes it the second episode in the season to not have anyone win invincibility, the first is Wawanakwa Gone Wild!.
 * Geoff and Gwen incorrectly place Bridgette was eliminated in Search and Do Not Destroy (after Eva) and Izzy in Hide and Be Sneaky (after that).

Continuity

 * It is revealed that Beth lied about returning the idol that she took from Boney Island.
 * It is revealed that Courtney told Leshawna about DJ's bunny.
 * This is the third time during the recap that Chris doesn't actually say who was kicked off in the previous episode (though he does show Izzy vanishing in a puff of smoke). The first time is Basic Straining where Chris doesn't mention Sadie's elimination (and nor is her elimination shown) while the second time is Search and Do Not Destroy where he did not mention Eva's second elimination.
 * This is the third time Chris has mentioned an actual episode's title during an episode. The first time was in Phobia Factor, and the second was when he mentioned No Pain, No Game during the recap in Search and Do Not Destroy.
 * This is the second time that someone swears at Heather. In this case, Owen swore at her in the confessional. The first time was Lindsay in That's Off the Chain!.
 * Duncan recalled about Geoff not voting for Bridgette in Hide and Be Sneaky and he messed up, which is probably another reason why Duncan voted for him.

Goofs

 * There are several goofs that show some campers' heads twice during the challenge involving the totem pole, such as when Geoff and Gwen are trying to remember whether Katie or Sadie were voted off fifth and there are two Sadie and DJ heads on their table. Also, when Chris is taunting Duncan during the Totem Pole challenge, there are two Lindsay heads on Geoff and Gwen's table.
 * Owen is supposed to be handcuffed to Heather by his right arm to her left arm; but while pushing the canoe, he's chained by his left arm, though Heather is still chained on the left arm.
 * The two are also shown to be unattached when Heather blows into an airbag in her confessional.
 * At the beginning of the episode, when Chris wakes up all the campers, they are all in their pajamas. However, after Chris lists the eliminated campers, they appear to be in their regular clothing.
 * There is a scene where Geoff and Gwen are arguing after Gwen admits she's never been to a party, when Geoff puts his hand behind his back, the cuff link is missing, but Gwen's hand is sticking out anyway. A split second later, it returns.
 * When Chris announces the winner of the final challenge, on Geoff and Gwen's table, DJ's wooden head is neither on the totem pole nor on the table. However, in the next shot, his head is to the right of the totem pole.
 * When Heather and Owen are in their canoe together, the canoe is level to the water, but in Up the Creek, when they shared a canoe, Owen's side was heavier than Heather's.
