Beaver

The Beaver is a small, buck-toothed, brown-furred animal that makes appearances throughout Total Drama Island.

Opening Sequence
The beaver appears in the opening sequence for Total Drama Island when a camera from underground pops up under it.

The Big Sleep
At a river, several beavers are seen building a dam, using a sleeping Owen as material. Also, Chris read a book to the five remaining campers who were awake about the history of beavers.

Wawanakwa Gone Wild!
A beaver bites Chris in the recap. Chris was about to curse at the beaver, but decided to stop mid-sentence and instead asks the audience if they think he needs a rabies shot. During the challenge in this episode, Geoff was assigned to catch a beaver, which he proceeded to do. He enters a beaver home and tries to persuade them to follow him but they slap him with their tail. This angers him and he tells them to stop but they continue to beat him. Eventually, he puts the beavers in the cage to end the challenge. The beavers later attacked Owen when he was locked in the cage with them and the other animals.

The Very Last Episode, Really!
An alarmed beaver was seen when Owen was sliding down the fireman's pole, and making a loud screeching noise that rang out throughout the whole island.

Total Drama, Drama, Drama, Drama Island
Harold mentions beavers to Noah repeatedly throughout the start of the episode, mentioning that he has diaries and sketches about beavers and how they differ to rats. Later in the episode, Heather crashes through the roof of a beaver dam after a hang gliding incident, and then yells at the beavers, who proceed to repeatedly smack her head with their tails.
