The teams wake up in the middle of the lake, where a returnee starts mutating due to toxic exposure, and seeks help from a fellow teammate. Meanwhile, another member tries to help a friend keep his secret under control. Someone is revealed to have found the idol, and asks someone else to keep it a secret. The finder is eliminated, but uses his discovery and his new friend to eliminate a mutant instead.


The episode begins with the camera panning at both teams sleeping on rafts out in the lake. Scott doesn't seem to remember anything after dinner. Cameron goes into a flashback when being served the "Turkey Buttolini", where he remembers Chef telling Cameron to enjoy his nap, before correcting himself and saying dinner, theorizing that eating mutant turkey knocked them out. Mike then finds a fedora hat and puts it on, commenting that he has always wanted one. Putting it on causes him to turn into Manitoba Smith and starts talking to Zoey. Cameron pushes her in the water and takes off the hat for Mike, in order to save their relationship. He makes a confessional about how he helps Mike with his disorder, and in return he helps him get rid of Scott. He also knows all the ways Mike goes into his different personalities, but hasn't mastered getting his original one yet. Dakota also makes a confessional. She states that now being bald, she has to focus on becoming friends with the rest of the contestants. She chooses Zoey as being the best choice to be seen out in public, post-makeover.

A mutant squid attacks the Toxic Rats.

Chris then arrives to start the next challenge, but Dakota interrupts him and starts revealing embarrassing things she learned about Chris while being an intern. However, no one pays attention as Dakota grows larger and her hair started to grow back, only that now in a neon green color. Chris then gets on with the challenge saying first that the Chris immunity statue has been found, and that the teams have to first race back to shore to earn a reward to use for the second part of the challenge. While rowing, Lightning runs into a mutated squid, slowing down the Rats. Meanwhile, Fang has found the Maggots, but Dakota punches it with her new strength into the squid's eye, freeing the Rats from it's tentacles. After the Maggots reach the location of the squid, it starts attacking them. Cameron then comes up with a plan to hit the front of the board launching everyone on the back to shore.

The Treasure Island of Dr. McLean (40)

Dakota mutates multiple times throughout the episode, usually when angered.

Once ashore, Dakota starts to look for Chris, and continues growing in size. She tries to jump and grab Chris in the helicopter. He dumps rewards on the ground, that the Maggots had won, which include a compass and a map of the island. Lightning and Jo are seen washed up on shore as Chris continues to explain that the teams have to find the chest in which Gwen and Sam are buried alive in, the latter who was knocked out by the meal from the previous night. Once seeing Sam knocked out, Dakota becomes angry and mutates further with an increase in height, orange skin, and even grows a tail. Chris allows the Maggots to head out, but stops the Rats. He gives them the "Penalty Belt" and gives them a metal detector. Jo states how that would be of any use to them as the chest is made of wood. Chris replies that it isn't and sets them off.

A furious Gwen contacts Chris through her cell phone while she is buried alive.

Back in the chest, Gwen calls Chris with her cell phone. He answers and makes fun of the farting noise in the background from Sam, which knocks her out. The Maggots get to a swamp that blocks their way. Mike finds a path out of the swamp and Cameron and him start to swim. Scott tries to make his team lose by showing the way through the swamp for the Rats. Dakota grabs Zoey and starts going to the water, but Scott reminds Dakota that Sam is losing air in the chest, which makes Dakota drop Zoey and race for Sam, leaving Scott and Zoey alone. Scott says he trusts Zoey enough to show that he has the immunity idol. Zoey is flattered by the fact he trusts her that much. He then tells her at least he doesn't hide things from her like Mike, and tries to make it seem like he is the only trustworthy person on her team, then they both go into the water. Later on, the Rats finally make it to the swamp. Jo sees the arrow Scott made and follows it through the water.

Scott secures Zoey's trust by showing her that he has the McLean-Brand Chris Head.

Back on the Maggots' team, Mike and Cameron try to tell Zoey not to trust Scott, but Zoey ignores them, still believes that Scott is a nice person, and doesn't notice when she walks onto the back of a giant mutant alligator, which startles her and her team, making them run in order to find a nearby tree. Scott and Cameron climb up, while Mike turns into Svetlana to get up, leaving Zoey by herself. She screams for Mike, which results in him turning back into himself, because of which Cameron figures out how Mike reverts back into himself and grabs Zoey. Dakota then fights with the alligator to save her team. While trying to find a way out of the swamp, Zoey asks for the compass after realizing that they had dropped the map back in the swamp but Mike tells her that he doesn't have it. Scott admits to having the compass in the confessional and attempts to hide it.

Lightning sees Dakota fighting and brags about how he could do the same, which Jo mocks as more alligators show up and start attacking him. Cameron tries to find an alternative to help the team to get out of the situation, which ends up being a thorn forest, and Dakota clears a path while fighting. Mike's shirt is caught on one of the thorns, turning him into Vito, and calls out for Anne Maria. Zoey stops and seems upset of hearing Vito again, but Cameron tries to pull his shirt back down. Jo and Lightning both get out as well and find a key under a rock with the metal detector, one for the belt lock, and one for the chest. Jo then hears Gwen underground and starts digging, while Scott tries to make his team dig away from the actual location of them, but Jo had already found Gwen, making the Rats have their second win of the season. Dakota then reaches for Sam in the chest, after tossing Gwen aside, and Sam wakes up to her cuddling him. Sam then states in the confessional that he thinks Dakota has gotten even more awesome.

Later that night, at the campgrounds, Dakota and Sam are seen spending time away from the rest of the Maggots, while Mike pulls Zoey over to say that they need to get rid of Scott, but Zoey is still unsure know who to vote for. Scott tries to get the secret about Mike by saying to Cameron that he appreciates that he helps him. Cameron didn't know it was a trick and tells him that Mike has Multiple Personality Disorder.

Dakota and Sam take the Hurl of Shame together for the last time.

At the elimination ceremony, Dakota first asks if Sam still likes Dakota, Sam says he'll always like her, and they make out, disgusting the other campers. Chris then tells that the camper voted off was Scott. He then pulls out the Chris idol, making Chris go to the next highest voted person, which happened to be Dakota with one vote, from Zoey, who didn't like her friendship that could potentially hurt her health. Dakota doesn't seem to care anymore about the show because of being too occupied with Sam and takes the Hurl of Shame.
