Imagination (episode)

During the 2009 Sontaran invasion of Earth, the Tenth Doctor momentarily switched over to an episode of a television series on a UNIT computer screen while waiting for the Sontarans led by General Staal to stop chanting, much to the concern of Colonel Alan Mace. The episode in question featured a blue-skinned creature dressed as a magician with a top hat, moustache, cape holding a wand and a bunny, presenting a show for "boys and girls". Seated in the audience were a young boy and a dog who the boy spoke to. (TV: The Poison Sky)
