Bigger! Badder! Brutal-er!

'''The fourth season begins, introducing a B|whole new cast, set at Camp Wawanakwa, which has turned into a bio-hazardous waste dump. The thirteen contestants are divided into two teams, the Toxic Rats and the Mutant Maggots. Two contestants build a close bond, and one contestant manages to annoy her entire team into them eliminating her that night.'''

Plot
The episode begins with an introduction from Chris, who explains that the season will take place at Camp Wawanakwa, similar to Total Drama Island, the show's first season. However, this time the season has a few changes, showing how the island has changed while they were gone. Next, all the contestants from the past three seasons, excluding Blaineley, are seen partying on a yacht floating past the island. Chris then announces that they will not be competing this year.

Instead, thirteen new contestants are then introduced from a different yacht arriving to the island. A full line up of all the competitors competing this season is then given. The viewers are first introduced to Jo and Scott, the former telling the latter to stay out of her way. Mike and Zoey are introduced, only to be interrupted by Lightning. Brick catches Zoey after she is pushed out of the way by Lightning, but drops her to give a salute when his name is announced. B and Dawn are then introduced, followed by Dakota, who blows a kiss to the camera. Anne Maria is then introduced while applying spray tan, and Staci brags about her aunt who invented fake tanner. Cameron is then introduced, but is knocked over by a flock of birds, followed by the final introduction, Sam. But to make a more interesting welcome, Chris activates a bomb, destroying the boat and causing the cast to fall into the water.

The contestants then had to swim back to shore. Cameron is seen drowning in the lake, but Lightning saves him while calling him a "little girl" in the process, causing Cameron to protest. Staci starts drowning, as she was wasting her energy telling lies. Mike and Zoey both say that they'll help Staci and Staci takes her hand and puts it on Mike's head drowning him. Zoey saves them both. Meanwhile, Jo swims her way to the shore first. However, Dawn was already at the shore, since she used a shortcut and didn't even get wet. Brick made it on the shore third. B, who was unknowingly carrying Cameron, makes it to the shore fourth.

Once everyone made it ashore, everyone gets to have a few moments of chatting. Then Chris announces that the team should follow a path into the woods, and then signals off a horn to awaken the beasts that have been inhabitants of the island. The cast screams as they run away from the loud rustling in the distance. After they have followed the path, they are united with Chris awaiting at a finish line. The contestants crossing the finish line determined which team they would be placed on, with B, Dakota, Dawn, Lightning, Sam, Scott, and Staci ending up on the Toxic Rats and Anne Maria, Brick, Cameron, Jo, Mike, and Zoey on the Mutant Maggots. Chris also introduces the "Chris head," which he is going to hide somewhere on the island. It is an item that, when found, will allow the contestant who finds it to stay in the competition even when voted out for the first time.

After that, Chris then gives out rewards for those who crossed the finish line first. Due to Jo crossing first, her team won a trampoline, and Lightning, the second to cross, got a hacksaw. From there, they must cut down a totem pole that is hanging from a tree, with a timed bomb strapped to it, which would detonate in seven minutes, unless they cut it down, slide it down a hill, and place it on a tree stump between the cabins. After the team had both successfully cut down their rope, they then had placed it on the river, where they would ride down a waterfall and onto a slope.

The challenge begins. Jo fell into the water after jumping on the trampoline, prompting Cameron to calculate exactly where Jo should jump on the trampoline to reach the axe. Anne Maria attempts to get the axe but jumps too hard which causes her to slam between the totem pole and the trampoline until Jo kicked the trampoline out of the way. Brick then attempts to grab the axe but couldn't separate the axe from the totem pole, leaving him vulnerable to a mutant squirrel which attacked the entire team. In the process, the squirrel shoots a laser which cuts the rope. Meanwhile, Lightning fails at climbing the tree to cut the totem down for the Toxic Rats, claiming there was butter on the tree that Chris put there to mess him up, to shrug off his failure. Afterwards, B manages to come up with a solution that involved the entire team stacking up against each other to reach the rope to cut down the totem. This made B's teammates, excluding Scott, impressed with B. The rats were in the lead and made it down the slope first after both teams went down a waterfall and B had his team lean forward to pick up speed and pass the Maggots. While they were racing on their totems, Owen makes a cameo in this episode, saying to Chris that the boat carrying him and his fellow "classic" contestants wouldn't stop. Chris tells him that they would not be competeing this season, and Chef sticks a bomb on his face, causing Owen to be launched off the island, screaming. The Rats arrived first and got to choose between a luxurious cabin and a regular cabin akin to the cabins from Total Drama Island. But once the Rats had chosen which cabin they had wanted, the Maggots came into the campground soaring and crashed into that cabin, thus destroying it. Even though the Rats successfully completed the challenge, the Maggots won because the cabin the Rats chose was destroyed and the Maggots' cabin was the only one left. A new cabin which is just a plain old cabin replaced the new one immediately via helicopter.

The Rats were then taken to the first elimination campfire ceremony, where Chris announced that this time instead of the eliminated player not getting a marshmallow, that player would get the Marshmallow of Toxic Loserdom. Scott, Lightning, B, Dawn, and Sam received regular marshmallows in that order. That left Dakota, who wasn't focused on competing, and Staci, who annoyed everyone by constantly talking. The Marshmallow of Toxic Loserdom went to Staci, who became the first contestant out of the season. Staci asks if that means she has to go to the Dock of Shame, to which Chris replies by announcing that this season's voted off players leave the game by the Hurl of Shame. Staci talks about how one of her ancestors invented catapults but before she could finish, Chris hurled her with the catapult.

 * Bridgette and Geoff are dancing.
 * A still-feral Ezekiel is at the front of the deck with his tongue out like a dog.
 * The bombs that were seen multiple times throughout the episode had the Team Chris is Really Really Really Really Hot logo on them, which was used in the previous season.
 * One of Mike's alternate personalities, an old man named Chester, makes his debut in this episode.
 * This is the first season where there are two teams and the amount of players on each team are uneven at the beginning.
 * The way Duncan and Gwen hold each other while making out is similar to how Courtney imagines in Boyfriend Kisser.
 * With the exception of Courtney's PDA, this is the first time Chris allows the contestants to bring along any technological devices with them; in this case, Sam's handheld video game and Dakota's cellphone.
 * Although they were confiscated later by Chris in Truth or Laser Shark.
 * This is the second time that a contestant contacts people in the outside world with their technological device; the first being Courtney contacting her lawyers in Total Drama Action.
 * Like in Not So Happy Campers: Part 1, the first two new contestants to be introduced is a girl followed by a boy.
 * Also, the first new contestant to reach the island is also a girl.
 * Currently, this is the only episode in which all of the original contestants and all of the new contestants appear. This reveals that they all survived their ordeal at the end of the previous season.
 * This excludes Blaineley, thus it is unknown what her condition is.
 * There is an alternate scene in Cartoon Network Poland when Anne Maria was introduced. Instead of spraying at Dakota for pushing her, she just pushed her back. Similarly, she doesn't spray at Staci on purpose but sprayed on herself which causes Staci to choke.
 * Chris's nicknames for the contestants
 * 1) Lightning- Captain Modesty
 * 2) Scott- Pit Sniffer
 * 3) Brick- Corporal Brick House
 * 4) B- Silent Treatment
 * 5) Cameron- Bubble Boy
 * 6) Zoey- Zoey the Lonely

Continuity

 * This is the second season premiere in a row in which a race to the finish line determines the teams; the first was Walk Like An Egyptian - Part 1 in Total Drama World Tour.
 * This is also the second season premiere in a row where someone is eliminated in it. The first being Duncan and the second being Staci.
 * This episode marks the highest number of contestants appearing in the episode without any lines.
 * Owen is the only original contestant who spoke.
 * Both couples making out consist of a male Killer Bass and a female Screaming Gopher.
 * Ironically, the couple who is often seen making out, did not.
 * DJ's dance is similiar to his celebration dance in Can't Help Falling In Louvre while Leshawna's dance is similar to that in Beach Blanket Bogus.
 * Geoff excited on the yacht is similar to when he first arrived to the island in Not So Happy Campers - Part 1.
 * There are several clues from the original cast that some time has passed between the end of season three and the start of season four.
 * Chris told Owen that he was "not competing this year." It could be assumed that about a year has passed since the events of Total Drama World Tour.
 * It can also be assumed from the length of Heather's hair growth from her Total Drama World Tour length back to its original Total Drama Island length that a significant amount of time has passed since Total Drama World Tour and this episode.
 * Likewise, Sierra is also shown with some hair growth under her hat, showing that she has recovered some of it since losing all of her hair in an explosion. Additionally, her legs have also recovered.
 * However, Alejandro was still inside the Drama Machine, highlighting that his injuries were incredibly extensive.
 * Similarly, Ezekiel is still a Gollum-like creature. This proves that not enough time has passed for Ezekiel to restore to normal or his transformation from the previous season is irreversible.
 * The reward for this episode is similar to the reward in Monster Cash, with the winners of the first challenge being allowed to pick the sleeping arrangements.
 * Also, in both episodes, one of the trailers/cabins seems obviously better than the other, but then something happens to bring them both down the same standard.
 * The cap Sierra is wearing is similiar to Cody's Drama Brother cap.
 * When Dakota's paparazzi first arrive, music from the Aftermath's intro can be heard playing.
 * This is the second season premiere that does not have a two part length. The first being Monster Cash.
 * This is the first episode Sierra and Alejandro appear but have no lines.
 * At least one member of the final two of the previous seasons appear in all four shots showing the veterans:
 * First shot: Gwen (Total Drama Island) and Duncan (Total Drama Action).
 * Second shot: Owen (Total Drama Island).
 * Third shot: Beth (Total Drama Action).
 * Final shot: Alejandro and Heather (Total Drama World Tour).
 * The final shot showing the original contestants on the yacht shows at least one member from all teams of the previous seasons:
 * Screaming Gophers: Trent and Heather.
 * Killer Bass: Bridgette, Geoff, Ezekiel, Courtney, Katie and Sadie.
 * Screaming Gaffers: Heather.
 * Killer Grips: Courtney and Trent.
 * Team Victory: Bridgette and Ezekiel.
 * Team Amazon: Heather and Courtney.
 * Team Chris is Really, Really, Really, Really Hot: Alejandro.

Goofs

 * Before the camera zooms in on Chris standing on the dock, the intern is nowhere to be seen. After it zooms in on Chris, he walks to the side of the dock and the intern appears.
 * The bombs Chris uses throughout the challenge are missing the logo on the front at several times during the episode.
 * As soon as the mutant squirrel hits the tree branch with its laser beams, the axe in the Mutant Maggots' totem disappears.
 * When B pulls Staci aside, the drawstrings on his sweatshirt are missing.
 * This goof also occurs when B receives his marshmallow.
 * Chris originally starts the bomb timers at the same time, but the Mutant Maggots' timer was about three seconds slower than the Toxic Rats' timer.
 * When Chris is naming the campers when they are arriving at the finish point, the wheels on his truck shift alignment.
 * Several goofs are seen when the veterans arrive:
 * Eva's mole is on the wrong side, while Leshawna's is missing.
 * Beth's badges are on her right side of her vest, while they are normally on her left.
