Scruffy

Scruffy was Duncan's pet tarantula. He is sent to Duncan from home in 2008: A Space Owen, along with the other cast members' packages from home. However, Scruffy is killed near the end of the episode because Harold accidentally smashed him while in The Vomit Comet.

Total Drama Action
In 2008: A Space Owen, the final five castmates are given presents sent from home. Duncan receives Scruffy, his pet tarantula, which makes him very happy. He immediately makes it obvious that he has affection for Scruffy by using baby talk and making kissing sounds at him. Scruffy immediately jumps on Harold after hearing a loud noise. Duncan tells him that he goes into kill mode when he hears loud noises. In the zero gravity chamber, Duncan gives Scruffy his pillow because he believes zero gravity takes a toll on Scruffy and not to Courtney, much to her protest that he would give up his pillow to a tarantula over her. Scruffy, much like DJ's bunny, has been able to tap into Duncan's soft side, due to the way he talks to Scruffy in an endearing tone and takes very good care of him.

Later, the contestants have to ride in the Vomit Comet space ride for the second challenge. Harold is the first to enter the ride and as he does so, Duncan loses Scruffy. At the last moment, Scruffy climbs up Harold's face, terrifying him. Harold then gets out of the ride after lasting a mere 5.3 seconds, because of the spider. When he gets out, Duncan demands to know what happened to Scruffy. Harold shrugs and turns around, and Duncan immediately notices Scruffy crushed on Harold's back, causing him to scream in horror and then threaten to beat up Harold. However, Courtney assures Duncan that Scruffy is in a better place that is most likely a lot better than where they are now. However, Courtney says in the confessional that she's glad Scruffy is gone so that Duncan will start to pay attention to her again. This prompts Duncan to vote for Harold in the elimination ceremony as payback for him "messing" with Scruffy. Duncan is noticeably pleased to see Harold going home for killing his pet.

In Top Dog, when the castmates choose the animals they want to train, Duncan chooses the chameleon as his animal friend. He says he chose it as a dedication to his deceased "reptilian" friend, Scruffy. Owen reminds him that Scruffy was a bug, but Duncan responds by warning Owen that nobody talks about Scruffy like that.
