Larry

Larry was Chris' pet Venus Flytrap, until Chris accidentally forgot it on the island after Total Drama Island ended. Due to the radiation that polluted the island, it became a giant mutant carnivorous plant with the ability to move around and eat people. Larry has a flower inside its mouth that serves as a receptor. Larry appears in the last two episodes of the fourth season, as well as one episode of the fifth season.

Total Drama: Revenge of the Island
In The Enchanted Franken-Forest, Chris announces that the challenge will be a race through the "Mutant Forest of Terror" to find the flower inside the mouth of a Venus flytrap named Larry. Later on Cameron and Zoey find it at the middle of a toxic bog and start thinking how to retrieve the flower. Meanwhile Chris is seen remembering the good times with Larry before he sold the island to a toxic waste company most to Chef's disappointment.

Later on, Lightning arrives to the bog and jumped inside Larry's mouth to catch the flower. However, the flytrap shuts him inside and then spits him out after he hit Larry from the inside. Cameron understands that the flower worked as a censor and tries to catch it with the help of Zoey and a rope, but Lightning manages to grab it first.

Larry gets up and uses its roots as legs to chase and grab Lightning, and Zoey takes the flower and passes it to Cameron. The flytrap managed to eat Cameron and Zoey. Lightning grabs the flower again and races through the finish line without being caught by Larry. Larry spits out Cameron and Zoey while Chris gives back its flower and cuddles with it.

In Brain vs. Brawn: The Ultimate Showdown, Larry shows up with the rest of the mutated creatures of the island. When a group of giant gophers attack Chris, Larry throws them away and Chris tells him to scare some loser contestants. Later on, Larry swallows Staci and grabs Jo, Brick, Mike, and Zoey. Cameron frees them by hitting Larry in the pelvic area, making the grass that covers part of its roots fall. Larry then runs away, covering its private area.

Total Drama All-Stars
After the events of the previous season, Larry has been quarantined with the rest of the mutated creatures at the "Fun Zone" on Boney Island, as seen in No One Eggspects The Spanish Opposition. Zoey and Mike find it with an egg (bringing up the question if Larry is a "Laurie", a female). Zoey steals its flower and attaches it to a flying moose, which Larry attacks. Meanwhile, Mike takes the egg, but it hatches before it can be put into his team's basket. One of the offspring has a head that remarkably resembles Chris', who whistles nervously after seeing it.
