Plot
The episode opens with Jasmine sleeping on her tree branch and being admired from afar by Shawn. He expresses concern over the fact that having a crush on her means that during a zombie apocalypse, he will have to watch out for her as well. Suddenly, he sees a mysterious creature covered in vegetation emerge from the lake. Believing that it was a zombie, Shawn flees in terror. The next morning, Sky and Dave are out foraging for food. Sky is just concluding a story of how she decided to aspire to become an Olympic gymnast but Dave is barely listening because he is too distracted by her. He accidentally mocks Sky's older sister, who she describes as her role model, and she stops to confront him on it. Dave then decides to tell Sky he likes her, and then asks if she reciprocates those feelings. Sky nervously belches and admits that she likes Dave back, but there is something else that needs to be said. Dave, however, prevents her from completing her sentence and states that they should just let things happen. At this moment, Chris announces that the contestants should meet for the challenge.

Ella asks Sugar if the two can talk, and Sugar rudely turns her down. Ella explains that since she is not allowed to sing, she wrote a friendship poem for her. Ella starts the poem, but Sugar isn't having it, yelling at her to "get out of her face." Sky then gives Ella some advice on how to deal with the situation. Meanwhile, Max is trying out new villainous nicknames with Scarlett engages him further. Upon reaching the beach, Chris is shown with his stubble shaved and his face frozen into a smile. Topher at first cannot seem to figure out what he has done differently until he realize that Chris must had used "slowtox" in order to make himself look younger. In the confessional, Topher panics that Chris' new, younger look may mean the producers won't consider him as a replacement host for the show.

Chris then explains the challenge - players will run across a dock, grab a dueling stick, and try to knock their opponents off and into the water. Each team will need to collect six sticks to form three X shapes in order to win the challenge. It is then that Sky notices that Shawn is missing which makes Jasmine a little worried. Chris sends Chef Hatchet to search for him, threatening that if Shawn doesn't arrive in time, he and another member of the Waneyihtam Maskwak will be eliminated. Meanwhile, Shawn is still freaking out after seeing the "zombie" from last night and decides to defend himself as he states that "self-preservation comes first." He covers himself in garbage to confuse the zombies into thinking he is one himself. Back at the beach, Jasmine says that she hopes Shawn is okay, but quickly adds that she doesn't care to appear loyal to her team.

The contestants swim to the docks to start the challenge. At Waneyihtam Maskwak's side of the dock, Sugar expresses annoyance that they had to swim without their bathing suits as they lost them in the blimp crash in the pilot episode. At the other team, Max is equally annoyed too. While Jasmine is still distracted by Shawn's absence, Topher decides to volunteer for his team first while Dave does it for his. The two of them grab their own paddles without even trying to knock each other off. Sugar and Samey are next and each pretends each other as their worst enemies; Samey imagines Sugar as her sister, Amy, while Sugar imagines her as Ella. Bored, Chris takes out his radio and order the release of Scuba Bear. Suddenly, a bear wearing a diving suit appears and knocks Sugar off the platform while Samey runs away, terrified. Max and Ella are next and Scarlett suggests that he wrap the copper wire he had around a dueling stick while she finds an electric power source which will make his dueling stick more deadly. Once Max arms himself, Scarlett pulls out an eel from the lake and threw it at Max's stick. Now holding a dangerous weapon, Max electrocutes Ella, causing her to fall into the lake. With the exception of Sugar, everyone startles at what happen to Ella. This act of "evil" made Max that he had accomplish a great goal.

Dave lifts Ella from the water and she apologizes for falling off the platform. A furious Sky demands vengeance for the other team's "low blow." As she crosses the platform to confront Scarlett, Dave puts Ella's fallen shoe back on for her. This act had made Ella was described by Ella as a "perfect fairytale moment" and that she has "found her prince," showing that she had now fallen for Dave. Sky attempts to avenge Ella by knocking Scarlett off, but Scarlett ducks in time. Jasmine goes against Dave, but she is too focused on wondering about Shawn to pay attention, giving Dave an easy point for Maskwak.

Meanwhile, Shawn is still wandering around the island, covered in garbage and pretending to be a zombie. As he trying to reach the waterfall, Chef discovers him and Shawn quickly run away, mistaken him for a zombie. Chef however, easily caught him and upon listening to him speaking, Shawn realizes that Chef is not a zombie but nonetheless tries to warn Chef about the zombie apocalypse and that they should hide behind the waterfall. However, when he looks back, the waterfall is gone. Chef dismisses it as him hallucinating from the stench. Back at the lake, Team Maskwak is catching up, with Sky earning another point. Ella volunteers to go next and tells Dave that she is repaying his earlier kindness by going in next and earn a point for their team. Sky notices and was confused with what Ella says to Dave. Ella faces Max again but when Max begin to taunts her, Scuba Bear appears again and tosses him into the lake. Before it could attack her, Ella manages to calm the bear down with a song.

Chris was furious with Ella's singing and threw his coconut drink at Scuba Bear to remove his state of trance. Angered, Scuba Bear turns its attention to Chris and swims towards his platform. Before he could attack him, Chef has return with Shawn and Scuba Bear returns to the lake. Now reunited with his team, Shawn immediately checks his team for bite marks, who are annoyed with his foul stench and at the same time being absent for some time. With his return, Jasmine is now relieved and begins to focus on the challenge. Realizing that Shawn believes that zombies are invading, Dave tricks him into thinking the other team has already transitioned into zombies in order to motivate him. Shawn is devastated that he had failed Jasmine for not waking her up and causes her to become a zombie and decided to put her out of her misery. Jasmine on the other hand tries not to use her abilities to the fullest, knowing that Shawn will be the next person to be eliminated. However, she didn't realize that Shawn would not do the same as he violently knocks her into the water. When he hears her speaking normally, Shawn realizes that she is not a zombie and says that he made a "big mistake."

The teams are now tied and Samey and Sugar go against each other again. Suddenly, the creature that Shawn saw last night pops out from the lake, revealing itself to be Amy. With her return, Samey's true identity is exposed, leaving everyone except Jasmine and Scarlett (who also knew of Samey pretending to be her sister) confused. As the twins begin bad mouthing each other, Sugar easily scores the final point for her team, giving Team Maskwak the victory. As the contestants are returning to their respective living quarters, Max is grateful for Scarlett's help and decides to take her as his sidekick. In the confessional, Scarlett angrily growls at him for calling her his sidekick. Meanwhile, Shawn tries to apologize to Jasmine, to no avail as she believes because of him, she would be the next person to be eliminated. In the confessional, Shawn is guilty that because of him, Jasmine now hates her and considering that he should think with his heart from now on. Jasmine decides to do the opposite and "get ruthless."

At the elimination ceremony, Chris gives Team Maskwak their reward and warns Ella that if she sings anymore, she will be automatically disqualified from the competition. Amy, Samey, and Jasmine are the final contestants without marshmallows and Jasmine accepts that she has been voted off and prepares to go into the cannon. However, she is the one who receives the final marshmallow. Amy and Samey each attempt to get the other off of the island, becoming embroiled in another fight. Chris is fed up with one posing as the other and eliminates them both to prevent future confusion.
