Who Left That There?

When the Blue Peter set is closed for the night, Alan, Brains, Tin Tin, K9, Twiki and Marvin The Paranoid Android and I sneak on and find some brightly coloured construction paper John Noakes and the other presenters left behind. Knowing K9 has been on the show before, we try our hand at making the biggest Thunderbird paper mache craft ever, through upbeat music and teamwork.
