Robot clowns assisted the chief clown in running the Psychic Circus. They were responsible for making people perform and entertain the Gods of Ragnarok. These clowns were not destroyed by them, but were used so that they would be entertained during the time when the humans and other species went to take part in the Talent Show. They were destroyed when the Seventh Doctor blew up the circus. (TV: The Greatest Show in the Galaxy)
