Having produced the live Alexander the Mouse, and the filmed The Adventures of Ho for his employers Associated Rediffusion/ITV in partnership with Firmin, Oliver Postgate and his partner set up Smallfilms in a disused cow shed at Firmin's home in Blean near Canterbury, Kent.
It was also the series that brought together Smallfilms with Sandra Kerr and John Faulkner (thanks to Michael Rosen's work with Kerr and Faulkner in Ewan MacColl's Critics' Group).
Although the series is made very much in the style of Oliver Postgate's Smallfilms, much of the background humour is in a similar vein to that of Aardman Animation's Creature Comforts.
He went on to compose the highly evocative music to the Smallfilms productions of Noggin the Nog, The Seal of Neptune, Pogles' Wood, Pingwings and Clangers.
