Shark

The Sharks appear in Total Drama Island during the theme song, and numerous times during the season. They have been responsible for the injuries and deaths of numerous interns, however, this is only shown in The Very Last Episode, Really!, when an intern on a bridge falls and gets eaten off-screen by a shark. The sharks can somehow breathe on land, but only when scared, injured, or relaxing.

In Not So Happy Campers - Part 2, the contestants have to jump off a cliff into a safe zone, surrounded by sharks. The only person who landed outside of the safety spot was Justin, who was spared by the sharks, due to their attraction towards him.

In Haute Camp-ture, the sharks were spotted getting seaweed mud baths alongside Beth. In Camp Castaways we see the shark as a vicious dangerous creature who wants to eat the top four. In The Very Last Episode, Really!, the sharks appear in a dangerous challenge where they devour an intern.

In Total Drama, Drama, Drama, Drama Island fourteen of the contestants dive into the water to get the case, but a shark eats it, causing the challenge to end. Chris then tells them that they are going to be in season two.

In the Total Drama Action theme song, Owen farts into one's mouth, making it choke. Two sharks later appear receiving spa treatments with Beth.

The sharks appear in Beach Blanket Bogus in a challenge where the contestants needed to stay on a surfboard above the water. The sharks still were in love with Justin, and when he fell into the water, one of the sharks rescued Justin from the water and gave him mouth to mouth resuscitation. After he revived, Beth and Lindsay went to comfort him, and the shark pushed the girls down with its fin, showing their "affection" towards Justin. Chris then gives the sharks break time due to union rules.

The sharks make a cameo appearance in Masters of Disasters. When the challenge requires the teams to escape from a submarine being filled with water, the Killer Grips open a hatch and a shark's head emerges and tries to bite at the team, however the team quickly shuts the hatch.

A shark is seen once again in Crouching Courtney, Hidden Owen as one of seven dangerous ingredients that Beth and Courtney had to cook to prepare for kung-fu noodle soup, until it was caught by a giant squid.

One of the sharks was Courtney's "animal buddy" during the episode's challenge. The shark was aggravating Courtney throughout the entire episode and Courtney managed to pick a fight with it. While punching the shark's stomach, the shark's lunch came out and Courtney prepared sashimi out of it and gave the meal to Chris and Chef. Then, a pack of sharks fought her in the second part of the challenge, and she nearly beat them, as she knocked out two of the three, but is thwarted when the last one threw her PDA over a waterfall, making her dive after it.

Trivia
