Bunny

The bunny is a furry, gray animal that has appeared throughout Total Drama. DJ had two bunnies as pets throughout the course of Total Drama Island.

Total Drama Island
DJ's first bunny made its first appearance in The Sucky Outdoors. During this episode, Courtney, who took the leadership role of the Killer Bass team, sent members of the team out to find food in order to survive. Instead of returning with food, DJ comes back with a bunny. Duncan gets excited because he initially believed DJ caught it for food, but DJ quickly refused to allow Duncan to eat it, saying it was his new pet and then named it "Bunny." In Who Can You Trust?, Chris told DJ about his next death-defying challenge, but DJ nearly forgot his bunny was in his front pocket. DJ then trusts Geoff to look after it while he is completing his challenge.

Later in the same episode, Bridgette and Geoff are about to dive into Lake Wawanakwa, when Geoff nearly forgets about Bunny being in his pocket. Geoff then places it on a lifeguard chair on the the Dock of Shame before going swimming with Bridgette.

Just as they get out of the water, Bunny is eaten by a snake, which is then caught by an eagle, and finally, all three are eaten by a shark. Geoff, too guilty to tell DJ the truth, told DJ he "ran away," sending DJ into a state of depression until he gets his next bunny from Duncan, who felt sorry for DJ's loss.

During the final challenge in Who Can You Trust?, Courtney sees Duncan using a carrot to catch DJ a new bunny and she realizes that maybe he is not as bad as he seems. DJ manages to win the race after seeing that Duncan has found (what appears to be) Bunny; however, DJ lifts his blindfold to see the bunny, causing Geoff and himself to be disqualified in the final challenge. DJ's second Bunny is also seen in Haute Camp-ture, where he suffers several accidents such as being caught by an eagle and thrown into a hot barbecue, and later being flung very high in the air. This second bunny is also seen during the final moments in the episode when it lands on Lindsay's lap and she thinks it was Tyler, who was sitting right behind her.

Loki
In Down and Outback, Crimson and Ennui adopt a bunny and name him Loki, since according to the goths, bunnies are a plague in Australia.

Other bunnies
Several other bunnies that are not DJ's pets, but look nearly identical, have appeared numerous times throughout the Total Drama series.

Total Drama Island
In the theme song, a bunny is seen with DJ and later attacks him after a dead fish is dropped nearby. In Brunch of Disgustingness, Trent pukes on a bunny after being sickened by the jellyfish pizza. In Search and Do Not Destroy, Bridgette's key is placed next to a seemingly-harmless little bunny. However, it roars loudly and ferociously at her and reveals a row of large, razor-sharp teeth, scaring her away, making her unable to complete her challenge. Two bunnies also briefly appear in the special, gazing at Justin.

Total Drama Action
A couple of rabbits that look like DJ's bunnies appear in The Princess Pride, gathering around Courtney while she was singing her "Perfect Prince" song. DJ mentions bunnies in his Lame-o-sine confessional, stating that they're his favorite animals because they are gentle.

Total Drama World Tour
A bunny makes its only appearance in Total Drama World Tour during the The EX-Files. It is first seen hopping across the terrain (which is later found to be a land mine field) effortlessly as Team Chris Is Really Really Really Really Hot tries to get into Area 51. It eventually crosses the boundary line into the dangerous zone and is instantly shot with a laser and runs past the team, screaming and charred.
