The Clangers was a British stop motion animated children's TV series that ran on the BBC from 1969-1972. And I grew up with them.
Clangers are basically these strange knitted creatures (knitted by the animator's wife) that wear roman armor, speak in whistles (Clanger language)--which btw is impossible not to mimic particularly if you are a child or even when you aren't--and live in burrows with dustbin lids for doors on a small hollow blue little planet far, far away.
The whistles made by the Clangers followed the rhythm and intonation of a script in English. Like Pingu, anyone listening--from whatever country--has the feeling that the Clangers are speaking to them in their own language. Which is genius.
