An 'Auton who survived the Nestene invasion of 2005 (TV: Rose) got a job as a window dresser in a shop, where they would sometimes pose as one of the mannequins so that they could be in the public eye.
They were eventually noticed by the Tenth Doctor and Rose Tyler who, after they were certain the Auton was not trying to take over the world, invited them to take part in the mall's Mannequin Challenge, in which they won. (COMIC: Untitled)
