Tweenies is a British comedy live-action Children's Sitcom created by Will Brenton and Iain Lachlan. Throughout the show's history, it has aired on both CBeebies and Noggin.
Before the show's release, in 1992, a pilot of the show was supposedly screened at Children's BBC. Possible information from this pilot is that the seven main characters made appearances and that Tweenie Dog was reworked and renamed to Doodles, but the Tweenies weren't. Nobody at BBC have confirmed or denied the existence of this pilot nor is there any information about the pilot anywhere else, making the existence of this pilot unconfirmed.
