Roddy is a rat who used to live in a posh house in Kensington, England with his owner Tabitha. One day, Tabitha along with her parents went on holiday so Roddy had the house to himself. But soon enough another rat named Sid ends up in the house and takes a liking to the place and decides to stay there much to Roddy's dismay.
Determined to get rid of Sid, Roddy lures him to the toilet claiming it to be a Jacuzzi. However Sid is aware of what's going on and retaliates by pushing Roddy into the toilet and flushes him down to the sewers. When there, he meets and befriends a rat named Rita Malone who agrees to help him get back to his home in return for one of his rubies since the one she had was fake.
After defeating the Toad (who tried to wipe out all the rats living in the sewers), Roddy stays with Rita in the sewers and lets Sid take his place as Tabitha's pet.
Roddy was initially pretentious, cowardly and pampered possibly brought on by being spoiled all of his life by Tabitha, the very rich girl who raised him.
Despite being a rat Roddy had an extremely sophisticated upbringing and spoke with fluency and sophistication in his mannerisms however he was also a very lonely individual as he grew up in a cage all of his life, cut off from his own kind and growing up with no family.
As the film begins to progress Roddy became assertively more loyal, brave, courageous, and protective rat, even protecting the entire colony of rats from being killed by The Toad. After saving everyone's lives Roddy was praised as a hero for his selfless deeds and finally became part of a family.
Roddy wears a black tuxedo (he eventually takes off his blazer and bowtie) and black shoes. Roddy has brown frizzy hair. When Roddy first arrived in the sewer, he saw life in new eyes.
