Doodle Doo was an obscure British television programme designed for pre-school children. The series originally ran on CBeebies between 2006 and 2010 at 9am and again at 1pm and 5pm. The show featured puppets called Dib-Dab, Scribble and Stick who interact with a human presenter, Chris played by Chris Corcoran. The programme is similar to SMarteenies, loose on the ''How to'' arts feature. Chris and the puppets explore making things from boxes, simple collages and so on. A story is featured, in which the puppets play characters using the items they have made. The three puppets have distinctive personalities. Dib-Dab (Yvonne Stone) is giddily enthusiastic, concerned for others and loves the colour pink so much, that whenever it seems someone else is going to get the pink paper, she will whimper with misery and longing; Scribble (Adam Carter) is a bit of a comedian with a fondness for puns; and Stick (Mark Mander) is rather nervous (similar to the character George from Rainbow, whom Mark Mander has also "played"), and often needs to be reassured by Chris. Stick enjoys chanting the word "Blob" whilst painting or glueing, and seems to get into a trance-like state doing so.
No episodes of the show are available online, clips are available on YouTube. The BBC have listed all the episodes on the CBeebies website but are no longer available for viewing.
I have found the theme song on youtube and you can find some episodes!
