Sid is a character in Flushed Away. He is a sewer rat who arrives in Kensington out of the drain and disappoints Roddy when he decides to stay. After Roddy fails to trick Sid into flushing him back into the sewer, Sid flushes Roddy down instead. When Roddy returns to his home with Rita he tries to pass Sid off as his brother but it is revealed that Sid and Rita know each other. Later whilst watching the World Cup Roddy realises The Toad's plan to drown the rats during halftime so he has Sid flush him down the toilet again but not before letting him take his place at the house. Sid is last seen at the house when Roddy's owner Tabitha arrives home from her holidays with a cat much to Sid's horror. He is voiced by Shane Richie.
