In Bigger! Badder! Brutal-er!, The Mutant Maggots are formed according to the random order the contestants end the race. Jo arrives first, becoming the first member. Brick arrives fourth and becomes the second member, while Zoey and Mike become the third and fourth members. Cameron becomes the fifth, and lastly, Anne Maria becomes the final member, making the Mutant Maggots one player short compared to the Toxic Rats. They perform well in the first challenge, managing to cut down their totem long before the other team after Mike switches personalities and hurls a rock at a mutated squirrel, causing its laser beams to sever the rope. However, even with a head start in the log race, they fall behind after they are passed by the Rats, who reach the campgrounds before them. It is an apparent victory, but the Maggots' log spirals out of control, landing in the Rats' cabin and destroying it. Amused, Chris declares the Mutant Maggots the winners. Since they win immunity, they are safe from elimination. The Rats having the vote off a camper thus evens out the numbers between the teams.
In Truth or Laser Shark, the team is seen in their cabins before the first challenge. During their walk through the forest, Anne Maria tries unsuccessfully to get B to engage in conversation. Mike and Zoey further develop their friendship, and tension begins brewing between Cameron and Jo. At the challenge, it is revealed that Brick wet his pants on the first and last day of school. Both teams tie for the first part. In the second challenge, although the lead repeatedly switches between the two teams, it eventually comes down to Cameron facing off against Dakota. He manages to win the challenge for the Maggots, saving them from elimination once more.
In Ice Ice Baby, the team loses the first part of the challenge by not having their whole team up the mountain first. In the second part, Jo beats Brick in a thumb-wrestling match, and thus is granted leadership of the Maggots. She also starts to exercise her skills in strategy to use her teammates to further her own game. The Maggots end up victorious in the end, due to Scott throwing the challenge for the Rats (framing B for the action), and go undefeated for the third episode in a row.
The Maggots begin to experience division in Finders Creepers when Mike, Anne Maria, and Brick are all upset with Jo's cutthroat attitude, as she doesn't care at all when Zoey and Brick are taken by the giant spider and insists that they move on without them. The team is also further divided by the love triangle between Mike, Zoey, and Anne Maria. In the end, after Brick and Jo are taken, Cameron takes it upon himself to lead the team, and although he is captured by the spider, he attacks it out of fear and saves the other contestants. Brick quickly escapes on the nearby zip-line, just ahead of Sam and Scott for the Rats. However, Chris declares the Maggots to be the losers due to losing four people, while the Rats only lost two. At their first elimination ceremony, Brick volunteers for elimination, feeling guilty for leaving his team behind in the end. Chris instead decides to switch him to the Rats, pitting him and Jo against each other at last.
In Backstabbers Ahoy!, Jo takes full command of the Maggots now that Brick is gone, and volunteers to be the diver for the team. The love triangle continues but does not hinder their progress in the challenge as much as it did before. The Maggots lose the first part of the challenge and receive a dinghy in poor condition for the second. Despite the clear disadvantage, they manage to pull ahead and win, thanks to Mike's alternate personality, Svetlana, and Cameron detonating two mines and beating the Rats.
In Runaway Model, the Maggots team is becoming a bit dysfunctional due to the conflict between Anne Maria and Zoey thanks to Mike's alter egos. In their first challenge, requiring them to capture a mutant animal and dress it to impress judges Chris, Chef, and Lindsay, Mike has some trouble with a frog that has the ability to teleport. Additionally, Cameron comes across a giant angler fish, initially believing it to be a beaver. They agree on dressing a beagle-sized maggot, and Anne Maria steps up to the plate. After she is done, the contestants are not pleased with her work, and Zoey steps in to take a shot at it. Cameron and Mike are pleased by the result and Jo just wants to get the show on the road, so the Maggots go with Zoey's fashion choices. Zoey's choices earn the Maggots some above average scores; however, the first challenge ends up being disregarded because of Sasquatchanakwa's kidnapping of Lindsay. In the challenge to rescue Lindsay, Jo volunteers to get made-over to seduce Sasquatchanakwa away. Once she reaches the top of the scaffolding, Lindsay and Sasquatchanakwa laugh at her causing Jo to punch Sasquatchanakwa off the cliff, thus giving the Maggots the win. Chris asks them to sit in on the Rats' elimination for a shocking team swap, placing Scott on the Maggots and Jo on the Rats.
In A Mine Is a Terrible Thing to Waste, the Maggots are separated when the two mine carts they are riding in go in different directions. They eventually regroup and win due to Brick smashing his team's Gilded Chris statue in order to save Cameron, Mike, and Zoey. At the last second, Anne Maria decides to quit the game because of the diamond that Ezekiel gave her. However, Chris reveals that the diamond is actually fake. Anne Maria tries to get off the Hurl of Shame but is catapulted off along with Brick. Chris later announces that Dakota has rejoined the competition as a contestant and that she will join the Mutant Maggots since they're down a member.
The Mutant Maggots' dynamic becomes even more divided in The Treasure Island of Dr. McLean. Zoey believes she has become a friend to Scott, but Cameron and Mike insist his intentions are not pure. The team's winning streak comes to an end, and Zoey sides with Scott to vote off the newly mutated Dakota, citing the girls' friendship is "hazardous to her health". While Scott receives the most votes, he wields the McLean-Brand Chris Head, and so Dakota is eliminated in his place.
