Colin (Ada)
IN SERIES: Colin is Daisy's dog, a Miniature Schnauzer, bought from a dogs' home where he was shortly due to be put down, to cheer Daisy up after she is dumped by her boyfriend Richard. He is named after the cardboard box Daisy played with as a child when she wasn't allowed to have a real dog. In the first series, Colin is abducted by an evil "freelance vivisectionist" and held at an animal testing facility. Despite his initial mortal fear of dogs, Tim eventually manages to bond with Colin by this time, so he leads Mike, Brian, Daisy, and Twist on a rescue mission to get him back home. In the second series, after Daisy has returned from her travels in Asia, it is clear that Colin feels rejected by her. In the final episode she discovers that he has been running off for secret visits with an elderly - and rather sinister - lady from the neighbourhood. Daisy manages to retrieve Colin but, remembering the countless times he has been neglected and the promise of widescreen TV, he runs off again. However, when the old lady suggests changing Colin's name to Lancelot he returns to Daisy to play happy families with her and Tim. He has the ability to tilt his head sideways, thus prompting anyone who sees this to sigh at his cuteness. In real life, Colin is actually a female named Ada (although this is incorrectly spelt as 'Aida' on the credits). A comment made by Nick Frost (Mike) during filming of a scene with Ada about dogs being unable to look up is referred to in the comedy film Shaun of the Dead.
