 A third series, narrated by Monty Python actor Michael Palin, was broadcast in the UK from 15 June 2015 on the BBC's CBeebies TV channel, gaining hugely successful viewing figures, following on from a short special broadcast by the BBC earlier that year.The new programmes are still made using stop-motion animation (instead of the computer-generated imagery which had replaced the original stop-motion animation in revivals of other children's shows such as "Fireman Sam", "Thomas & Friends" and "The Wombles").
