Wilksy

A man thought he was in a London pub with his friend Wilksy. However, he learned from the Seventh Doctor that he and several other customers had been abducted by an alien — the bartender, Paddy O'Brien — and that some of the patrons, including Wilksy, were just part of the trap. When the Doctor defeated O'Brien, the man and the others were returned to London, and Wilksy vanished. (PROSE: The Time and Tide)
