Durrrin

 was a Shivashian dancer that took part in the Universal Dance/Off (nine million and two) at the Cosmos Ballroom with his dance partner Laliaargh. He and Laliaargh were transported to Birmingham in 2009 to try and repair the crashed Terpsivore spaceship. Durrrin, along with Laliaargh and Donna Noble managed to turn off the ships self-destruct sequence and repair it by doing the conga. Durrrin and Laliaargh were then taken back to the Cosmos Ballroom and found that the individual adjudicator judging the dance competition had fixed the results in their favour leading to Space War III.
