The Clangers

Clangers is a British stop-motion children's television series, made of short films about a race or family of shrew-like creatures who live on, and inside, a small moon-like planet. They speak only in a whistled language. They eat only green soup and blue string pudding. The programmes were originally broadcast on BBC1 between 1969 and 1972, followed by a special episode which was broadcast in 1974. The series was revived in 2015, broadcast on CBeebies.
