How do Clangers communicate?

The Clangers are back!

The pink, long-nosed, inventive and loveable mouse-shaped creatures who live on a small blue planet out in the starry stretches of space return to TV screens on Monday in a CBeebies remake, narrated by Michael Palin.

Whilst the show has had a cosmetic makeover, the creators say that the new version is very faithful to the original.

Series producer Dan Maddicott gave more details - starting with the key question of how Clangers communicate.
