The programme is presented by a puppet named Pob (played by puppeteer Robin Stevens), who speaks with a speech impediment and who supposedly lives inside the viewer's TV (the casing and red, green and blue electron guns visible behind him).
In a typical episode, the celebrity visitor to the show finds a label attached to a piece of string on the gates of Pob's garden; The celebrity guest then follows the woollen string, winding it as they go, and encountering a second label; Ultimately the wool is found to be Pob's unravelled jumper, and he is awoken to trace his name on the screen.
Over the course of the programme, the celebrity guest reads a story, and solves a word puzzle with Pob.
The visitors, many of them well known as actors, included Roy Castle, Jan Francis, Charlie Williams, Madhur Jaffrey, Brian Blessed, Brian Patten, Hannah Gordon, Su Pollard, Kathy Staff, John Duttine, Ross Davidson, Spike Milligan, Toyah Willcox.
