Raffalo (portrayed by Beccy Armory) was a short blue-skinned alien who appeared in Doctor Who episode "The End of the World". She was from Crespallion, which was part of the Jaggit Brocade, affiliated to the Scarlet Junction, in Complex 56. Rose Tyler gave her permission to talk, which very few guests did. Rose was shocked that they still had plumbers in 5,000,000,000. They chatted and Raffalo made Rose realise what she was getting into with the Ninth Doctor.
While carrying out her duties as a plumber on Platform One, Raffalo encountered the metal spider drones that Lady Cassandra had set loose on the station. She was last seen being dragged inside a ventilation duct.
