Jigsaw is a BBC show aimed at children between the ages of 4 and 7 that combined elements of puzzle solving and entertainment, which was broadcast from 16 July 1979 until 15 June 1984.

Written and directed by Clive Doig, the show was presented by mime artist Adrian Hedley, Janet Ellis and "Jigg" - a giant floating orange jigsaw piece, voiced by John Leeson later replaced by Tommy Boyd then Howard Stableford.

Featured supporting cast also included Paul Clayton, Biggum the giant (played by Leeson) and Wilf Lunn who appeared as a mad inventor.

Other unusual characters included Pterry, a puppet Pterodactyl (operated by Joe Barton); Cid Sleuth (played by David Cleveland), a Sherlock Holmes-looking bumbling detective plagued by a mysterious burglar (David Wyatt); Hector The Hedgehog; and the O-Men (Sylvester McCoy and David Rappaport), a pair of hapless superheroes summoned by saying any six consecutive words containing a double-O (even the same word repeated six times counted once, albeit inadvertently - Dot said 'coo' four times imitating a pigeon, then Adrian mocked her attempt, saying it twice more to trigger the summon).

The theme used for the Noseybonk segments was "A Hippo Called Hubert," composed by Joe Griffiths and also used in Kentucky Fried Chicken's Charlie Chickenhawk and Frederick Fox advertising in Australia between 1984 and 1987.
