Weylanni
From Tardis Wiki, the free Doctor Who reference
The Weylanni were fictional aliens from Professor X, introduced in series 3, episode 12, "The Rage of the Weylanni". They were described by Ellis Andrews, a fan of the series, as looking like "men in boiler suits with papier-mâché faces". Andrews did not consider this to be one of the series' better stories.
The Fourth Doctor and company found themselves facing off against the Weylanni when they crossed a door connecting the Doctor's world and the Land of Fiction. (AUDIO: The Crooked Man)
