Larry was Chris' Venus Flytrap pet, until he accidentally left it on the island after Total Drama Island. Due to the radiation that pollutes the island, he became a giant carnivorous plant with the ability to move around and eat people. It has a flower inside his mouth that serves as a receptor. He only appears in "The Enchanted Franken-Forest" and "Brain vs. Brawn: The Ultimate Showdown", although serving a minor antagonist of the season.
In "The Enchanted Franken-Forest", Chris announces that the challenge will be a race through "Mutant Forest of Terror" to find the flower inside the mouth of a venus fly trap named Larry. Later on, Cameron and Zoey find him 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, much to Chef's disappointment.
Afterwards, Lightning arrives to the bog and jumps inside Larry's mouth to catch the flower. The fly trap shuts him inside, but then spits him out after he causes him indigestion. Cameron understands that the flower worked as a censor and tries to catch him with the help of Zoey and a rope, but Lightning grabs it first.
Larry gets up and uses his roots as legs to chase and grab Lightning. Zoey takes the flower and passes it to Cameron, but the fly trap manages to eat Cameron and Zoey. Lightning grabs the flower again and races through the finish line without being caught by Larry. Larry spits out Zoey and Cameron while Chris gives back his flower and cuddles with him.
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 eats Staci and grabs Brick, Jo, Mike and Zoey. Cameron frees them by hitting Larry to his weak point, making the grass that covers part of his roots fall. Larry runs away, covering his private area.
Larry was likely to be quarantined along with all the other animals at Camp Wawanakwa when the government took control of the contaminated island at the end of the finale.
