Chef Hatchet's Total Drama Yum Yum Happy Go Time Candy Fish Tails is a type of candy made by Chef Hatchet.

During Super Happy Crazy Fun Time Japan, the contestants have to make a Japanese-style advertisement to promote the product. When Alejandro tastes some of the candy, he immediately spits it out and compares the candy to tasting like "rotting fish intestines with a side order of fermented squid and dirty hockey equipment".
Team Chris Is Really Really Really Really Hot's commercial is a loose parody of Godzilla. Owen, dressed as a monster, terrorizes a tiny model of Tokyo while Alejandro, Izzy, Noah, and Tyler act as soldiers who fret over the monster demolishing their city. Alejandro puts a stop to Owen's destruction by throwing a Candy Fish Tail in his mouth, and the team sings an anthem about the candy before the commercial ends. Their project is titled "Monster Rampage".
Team Victory creates a short film in which Harold plays a lone samurai riding his horse into a village. Bridgette, Leshawna, Lindsay, and DJ act as villagers who beg the samurai for food, but the samurai starts to die moments after his arrival. A lone beach ball rolls onto the set and is impaled by Harold's sword. Harold then a Candy Fish Tail to his mouth while somberly reciting a song about the Candy Fish Tails. This commercial is titled "A Samurai's Lament" and, due to its obscurity, ends up sending Team Victory to elimination.
Sierra and Cody make a commercial for Team Amazon that consists of random clips, including spinning hockey masks, exploding doughnuts, and Sierra singing loudly into a megaphone. Before the advertisement ends, a seagull with its neck caught in plastic six pack rings eats a Candy Fish Tail and a gong sound is heard in the background. This commercial is titled "Huh?" and wins Team Amazon the challenge.
Noah mentions the Candy Fish Tails again in Anything Yukon Do, I Can Do Better, asking Chris if their next location is some place without Candy Fish Tails. Owen, who is sleeping beside Noah, wakes up upon hearing about the candy and excitedly asks where he can find some.
