Squirrel

The Squirrel appears numerous times throughout the Total Drama series.

Opening Sequence
At the beginning of the song, a camera pushes a squirrel out of a hole in a tree. Soon after, squirrels are seen peacefully sitting by DJ. This continues until a fish falls on him, causing the squirrel and all of the other animals to attack him, even though he is supposed to be an animal lover.

The Sucky Outdoors
The squirrels make fun of Katie and Sadie when they get lost in the woods by mimicking their argument by mouthing the words and making the faces.

X-Treme Torture
Early in the morning, an annoyed squirrel smacks a tweeting bird off a tree.

Search and Do Not Destroy
A squirrel is seen coming out of the tree with a cup of coffee.

Hide and Be Sneaky
Gwen punches a squirrel who is near her hiding spot before it can reveal her location to Chef who is hunting the contestants to eliminate them from the challenge.

Camp Castaways
A squirrel is seen floating away from the island, on top of a submarine.

I Triple Dog Dare You!
A squirrel in the forest turns dramatically towards the camera after hearing Heather scream.

Total Drama Action
Like almost everyone in the show, the squirrel seems to have a crush on Justin, as it has fainted due to his "powers" in some episodes.

Dial M for Merger
The squirrel is seen falling into the tomato bath in which the cast is sitting in after smelling their stench.

Aftermath: Bridgette Over Troubled Water
The squirrel makes a brief appearance in the aftermath in a never-before-seen clip of Harold's "best" moments. It is also seen punching Harold in the face, with its fist enlarging to a much greater size, after it becomes annoyed with his stream of trivial facts.

Aftermath: Revenge of the Telethon
The squirrel is seen during the "DJ's World of Animals" segment, in which a clip is shown of DJ feeding a squirrel food in Central Park, when a bicycle suddenly runs over the squirrel, squishing it to the ground.

Awwwwww, Drumheller
Two squirrels were among all of the animals and Ezekiel seen evacuating from the Total Drama Jumbo Jet moments before Sierra accidentally blew it up.

Dawn's Audition Tape
During Dawn's audition, a squirrel appears on a branch nearby. She takes it in her hand and explains that she's going to use her money to help Mother Earth. The squirrel then is taken away by an eagle, shocking her.

Bigger! Badder! Brutal-er!
The squirrel returns in Bigger, Badder, Brutal-er!. Because the island was turned into a temporary waste dump, Camp Wawanakwa has become radioactive and the squirrel has mutated into a monster.

Its eyes blink vertically opposed to horizontally, along with its tongue being extremely long and it having the ability to shoot lasers from its eyes, as well as becoming completely hairless. In addition, it became either a carnivorous or omnivorous animal, as it ate a butterfly. When the contestants first arrive on the island, they are told by Chris to run from the "monster".

The contestants however, believe it is a large monster, as opposed to what it actually turns out to be: the squirrel. Dakota later tries to pet the squirrel, wanting it, but it proceeds to shoot lasers at her.

During the first challenge, while Brick tries to pull an axe from his team's totem, the squirrel appears again. After being agitated by Mike, the squirrel shoots more lasers from its eyes, cutting down the Mutant Maggots totem, giving them a lead in the challenge.

Truth or Laser Shark
A squirrel was seen eating a chocolate bar and watched Jo and Brick run into each other, and laughed when it happened.

Runaway Model
A squirrel was seen hanging around in some scenes and joining in on the mutant animal fight in the woods.
