Larry

Larry was Chris' venus flytrap pet, until Chris accidentally forgot it on the island after Total Drama Island ended. Due to the radiation that polluted 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.

Total Drama: Revenge of the Island
In The Enchanted Franken-Forest, Chris announces that the challange 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 most to Chef's disappointment.

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

Larry gets up and uses his roots as legs to chase and grab Lightning and Zoey takes the flower and passes it to Cameron. The fly trap 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 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 Jo, Brick, 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 mutated creatures at Camp Wawanakwa when the government took control of the contaminated island at the end of the finale.

 * When Larry growls, the sound he gives out resembles the T-Rex growls from Jurassic Park.
 * Larry is an homage to Audrey II, the giant man-eating plant from the 1960 B-movie The Little Shop of Horrors; it's revelation that it can walk on it's roots towards the end, though, is more like Audrey from the 1986 musical film version.
