Skunk

A Skunk is a black and white woodland creature that sprays a foul-smelling odor as a means of defense.

The skunk first appears during the Total Drama Island theme song with DJ and all the animals, then attacking DJ after a dead fish is dropped on his head.

In X-Treme Torture, during the campfire ceremony, Geoff smells so bad that he is forced to sit on a tree branch far away, with only a skunk for company. In Brunch of Disgustingness, one of the dishes the campers must eat is Skunk Shakes, which Chef makes using actual skunk spray that is liquified into a drink.

In No Pain, No Game, Trent had to jump over several skunks for his challenge. One of the skunks sprayed him right in the face, causing him to collapse and lose the challenge.

In Search and Do Not Destroy, Gwen must retrieve her key out of a skunk hole. However, she has trouble doing so as she has an aversion to skunks. Trent helps her out by pouring water into the hole, causing the skunks to float out, without spraying, which allows Gwen to safely retrieve her key.

In Hide and Be Sneaky, Bridgette encounters a family of skunks while trying to hide. Nervously, she backs away, but her foot is tangled up in a string of lights, and pulling too hard on them causes a barrel to fall over. The loud noise startled the skunks, and they sprayed Bridgette. She smelled bad for the rest of the episode, and her stench had a part in her elimination. Geoff admits to not voting her off, but is still too repulsed to kiss her as she is leaving the Dock of Shame.

Trivia

 * In Best. Game. Ever., one of the tasks in the Dial M for Merger challenge is to retrieve a skunk from the southern woods and bring it back to Chris to create a stink bomb. One of the favors your ally asks of you is to give a "skunk in a box" to another contestant.
 * It is one of the few animals to appear only on Total Drama Island.
