Scruffy

Scruffy was Duncan's pet tarantula. It was sent from home in 2008: A Space Owen, along with the other castmates' packages. Scruffy was killed near the end of the episode, because he was accidentally smashed in The Vomit Comet by Harold.

2008: A Space Owen
After waking up early in the morning, the final five castmates are given something 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 baby talking to him and making kissing sounds at him. Scruffy immediately jumps on Harold, after hearing a loud noise, after Duncan tells him that he jumps with loud noises. In the zero gravity chamber, Duncan gives Scruffy his pillow, and not to Courtney, much to her protest that he would give it 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, Harold is the first to enter the Vomit Comet space ride, and Duncan loses track of 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 Scruffy, and Duncan notices Scruffy crushed on Harold's back. He screams in agony after this and threatens to beat up Harold, but Courtney assures Duncan that Scruffy is in a better place, and that place 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, saying, "Teach you to mess with Scruffy!" Owen shares his vote for Harold, which eliminates him. Duncan is noticeably pleased to see Harold go home.

Top Dog
When the castmates choose their animals 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 saying "Nobody talks about Scruffy like that!"
