Laliaargh

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