Clangers

The Clangers was a popular children's TV show broadcast in Britain during the 1970s. It was made using puppets.

The Master watched an episode of The Clangers while he was imprisoned by UNIT, and was quite amused by it. He joked to George Trenchard that they "seem[ed] to be a rather interesting extraterrestrial lifeform". Trenchard, believing the Master really thought the Clangers were aliens, told him it was just a puppet show. The Master showed visible frustration with the man behind his back. (DW: The Sea Devils)
