The blowfish is used in the extreme cooking challenge in Who Can You Trust?, when Lindsay and Trent, are up against Bridgette and Geoff. According to Chris, the fish contains enough poison to kill at least thirty people. They must be sliced very carefully to cut around all the poisonous organs. He also says that the poison paralyzes the nerves and there's no known antidote. Bridgette is able to successfully prepare the blowfish in the form of sushi, which she feeds to Geoff. Geoff is shown to not be harmed whatsoever by it. Lindsay, however, prepares a mangled mess of a dish for Trent (whom she made to look tastier with a ketchup smiley face), who nonetheless eats it. After eating it, he collapses, vomits and convulses, having been poisoned by it.
The blowfish is next seen in Crouching Courtney, Hidden Owen when the girls have to prepare a Japanese dinner for the winner of the reward challenge. This includes a dish called Kung Fu Noodle Soup, which is made of vegetable broth, noodles, and the "seven deadliest species of fish known to man" (including the blowfish). Beth claims she is allergic to fish when they're still alive, so she can't help Courtney cook it. Courtney eventually incorrectly manages to cook the dish, as Owen is poisoned after tasting the soup.
Butterflies occasionally appears throughout the series. In Total Drama, Drama, Drama, Drama, Island, one can be seen flying around Justin's head. In Bigger! Badder! Brutal-er!, a butterfly landed on Cameron's head while he is using the confessional.

The chameleon is introduced in Top Dog's animal buddy challenge, when Duncan chooses it. He does this in memory of his beloved pet, Scruffy, although he fails to remember that Scruffy is an arachnid and the chameleon is a reptile. He tries to train it to turn itself into the color of his mohawk. However, it fails several times. This is partly due to the fact that Owen kept sabotaging the pair by spray painting Duncan's mohawk a different color, so that the chameleon would change to match the color but get scolded by Duncan. By the end of the first challenge, the chameleon finally changes into the right color. In the second challenge, the chameleon is supposed to be Duncan's guide out of the woods. Duncan claims that chameleons are stupid animals and mentions that he should have picked the bear so he could hitch a ride back to the film lot without having to walk. The chameleon then camouflages with the scenery and Duncan believes it is missing for the rest of the episode. It does not reappear until Owen points out that Duncan and his chameleon are bonding, and it then reappeared on Duncan's head. Having blended in with his mohawk, Duncan then realizes it was on his head the whole time.
In Phobia Factor, it is revealed that Tyler has an irrational fear of chickens. The reason he is afraid of them, however, is never given. During his challenge, he couldn't last more than three minutes in the chicken pen. He even panicked to the point that he went into the fetal position, rocking back and forth. Tyler was later voted off for this and was sent on the Boat of Losers with tears in his eyes. Mainly, it was increasingly chicken related puns from his ex-teammates, only to be stopped by Courtney, that made him upset. He screams in horror when he realizes that the Boat of Losers is filled with chicken cages. It was most likely courtesy of Chris and Chef. In I Triple Dog Dare You!, when Heather is forced to act like a chicken, she has another chicken beside her.
In So, Uh This Is My Team?, when Beardo pulls his cord for his parachute pack, a chicken comes out. A chicken known as "Clucky" appears in I Love You, I Love You Knots. She is stated to be from the CIA, and can tell if someone is lying or telling the truth. She develops a conflict with Rodney after the latter mocks her, which leads her to take revenge by electrocuting him, resulting in Waneyihtam Maskwak winning the challenge, and Clucky being taken away in a straightjacket. Clucky's design is different from the regular chickens that appear prior to this, as she didn't have dotted eyes. Later, it is implied that Chef cooks Clucky for dinner. Future appearances of chickens would use this new design along with the older ones, the latter design also includes alternate colors.

However, the chipmunk bites him on the nose and Owen falls off of the tree branch he is on because he is too heavy. The chipmunk lands safely with a parachute, which it pulls out of nowhere. Owen eventually leads the chipmunk into the cage and screams at Chris to close the door. Chris asks if he is sure about that because when he closes the door, Owen is attacked by all of the animals including the chipmunk, because he locked himself in.

Owen doesn't seem to mind, as he does not show any signs of pain when they bite him all over his entire body, even joking that they looked like a fur coat. When Owen and Noah run into Jack the Ripper, Owen attempts to make the dogs attack the Ripper, but they attack him instead. One of the dogs manages to steal a sausage from Owen's pocket, which he accidentally kicks out of its mouth and into the Ripper's hands, prompting them to attack him instead.

The emus are fond of pecking and/or attacking the contestants and Chris' interns. Because of his weight, Owen is required to ride two emus and even so, both birds still couldn't carry him. As a result, Owen is the last person to reach the destination and by then, both emus are visibly exhausted.
In Last Tango in Buenos Aires, emus are used for the second challenge. Each team must catch an emu using boleadoras and carry it to the Chill Zone. Despite its presence, emus are not native to Argentina.

However, it is not an easy task for Leshawna, as the frog irritates her by constantly luring her into unusually deep puddles instead of walking into the bucket. Leshawna begins to grow desperate in order to catch the frog, even trying to lure it towards her with cheese, which frogs don't eat. The frog still ignores Leshawna's pleas and forces her to come closer to her. Leshawna tries to ignore this trick, but eventually moves closer and ends up falling in the water again.

It then goes in the main lodge through a hole.
It's then shown next to Cameron with the latter very excited to see it. He called it a "cute Apodemus sylvaticus". He was about to touch it until the rat flies in the air using his mind. All of the contestants then run out of the main lodge to avoid getting hit by a refrigerator with presumably the rat's mind. It is also possible that his mind also controlled Mike for a moment as he was shown not running with the others as well as getting thrown out and hitting the ground on his face.

They emerge from a chamber in the ancient pyramid traversed by the contestants after DJ accidentally destroys a mummified dog he finds, indicating that they are a part of the Curse of the Mummified Dog.
The beetles attack and devour an intern and then prepare to attack the contestants, who then sing Lovin' Time in an attempt to soothe them into mating with each other rather than attacking them.

In Brunch of Disgustingness, when Trent is in the confessional, a snake is seen with a rabbit in its stomach, though it's unclear if this rabbit is DJ's Bunny or just a different bunny.
It briefly appeared in No Pain, No Game, wrapped around DJ as one of his challenges in a montage sequence. A snake held the key to Izzy's treasure chest in Search and Do Not Destroy, and Izzy comments on how it's friendly; it then bites her head, causing her to pass out. The last, and probably most significant appearance of a snake was in Camp Castaways. It first arrived by falling out of a tree just as the final four campers were reunited, forcing them to take refuge in the tree house, which was too high for it to reach. Duncan describes it as "a 50-foot python with an attitude." It kept them trapped there for several hours, according to Gwen, before Owen knocks it out with Mr. Coconut, allowing them to finally escape the treacherous animal.
In Total Drama World Tour, a snake made a brief appearance in the second aftermath sideshow called "DJ's World of Animals," as one of the animals that DJ affected during his curse. The snake immediately attacks Blaineley, and wraps itself around her neck after she unlocks the cages containing the animals.

The snapping turtle is a reptilian animal that has a shell, into which it uses for defense. It also has a very powerful jaw. It is one of the many animals that appear throughout the Total Drama series.
In No Pain, No Game, Duncan's challenge from spinning the Wheel of Misfortune was to avoid the barrage of the nastiest snapping turtles in all of Camp Wawanakwa, while Chef Hatchet launches them at him with a hockey stick. Duncan manages to survive the required ten seconds, but not before being completely covered by turtles that were biting his entire body.
In Broadway, Baby!, during the Big Apple challenge, DJ volunteers to get the apple for his team, but is attacked by the turtles. When he finally manages to get away from them, there is still one is hanging on to his shirt. DJ pries it off, nicknaming it "Mr. Nibbles", and throws it back into the water, only for it to be eaten by a larger snapping turtle, which continues the running gag of DJ's Curse of the Mummified Dog.
In Aftermath: Revenge of the Telethon, during the "DJ's World of Animals" segment, meant to raise money for Total Drama, the clip of DJ making the snapping turtle get eaten by a larger snapping turtle is shown again. The turtle is also shown in a cage with the rest of the animals that DJ had hurt. When Blaineley releases all the animals in an attempt to get more money for the telethon, the turtle attacks Bridgette.
In The Bold and the Booty-ful, a single snapping turtle appears as a booby trap for Mal and it bites him on the hand. However, Mal growls at the snapping turtle and it ran off whimpering.
Stymphalian Canadian geese
These geese live in nests on the cliffs of Boney Island, where they attacked the Screaming Gophers. They eat bread, like any other goose, as seen in Up the Creek, when Cody throws bread at them and they begin to eat it and stop chasing them. They may be omnivores, as they eat the bread, but also attack the campers.
During the campers' time on the deserted island in Camp Castaways, Duncan finds a particularly large egg. Gwen finds out about this egg, and as they were both hungry they begin to fight over it. A goose then flies over them and cries out, implying that it is a goose egg. It then attacks Duncan to get its egg back and carries him off the ground. Gwen attempts to capture the goose by throwing a lasso around its leg, but the goose is easily able to lift Gwen off the ground as well. It later releases them for unknown reasons.
They reappear in One Million Bucks, B.C. where one steals Heather's new wig, attacked Harold at the end of the episode for "stealing" it's egg, and Heather attacking the one that stole her wig. These geese however, may have been animatronic.
In I Love You, I Love You Knots, Chef brings Sugar a tarantula on a platter for her dare. She picks it up and eats it before Chris has a chance to tell her she only has to pet it. Despite the unexpected turn, he decides to let it count as a point for the Waneyihtam Maskwak.
A toucan appears in The Am-AH-Zon Race.
In Jamaica Me Sweat, during DJ's final run at the longboard challenge, he ended up hitting several animals including a walrus when Alejandro reminded him of his curse. Finding it ridiculous that a walrus somehow ended up on the track, DJ yells that "It doesn't even make any sense!".
A wolf can be heard occasionally heard howling in the background at night during a few episodes of Total Drama Island. The silhouette of one can be seen usually before the Campfire Ceremony. In No Pain, No Game, the wolf is replaced with Chef Hatchet.
In Search and Do Not Destroy, while DJ was attempting to capture his key, the woodpecker is shown pecking at the branch, slowing DJ down.
A seemingly normal woodpecker was shown in Runaway Model trying to peck at Anne Maria's hair but failing to make any progress.
