Tomorrow's edition of CBBC magazine programme Blue Peter will be a special programme dedicated to Peter Capaldi as the incoming Doctor and featuring the winners of last year's competition to design sonic devices for the Paternoster Gang of Madame Vastra, Jenny Flint and Commander Strax.
The 12th Doctor: A Blue Peter Special - presented by Barney Harwood, Lindsey Russell and Radzi Chinyanganya - takes the three young contest winners Connor, Arthur and Amber behind the scenes of Doctor Who to see their sonic gauntlet, lorgnette and hat pin in action, where they also meet Capaldi.
In addition, Dan Starkey, who plays Strax, talks about how he is turned into a Sontaran via prosthetics, while the make-it will be a TARDIS T-shirt.
The programme, which airs at 5.30pm, will be repeated on Saturday at 8.20am and then at 6.25pm as part of a range of Doctor Who-related programmes being shown on CBBC from 1.40pm - also comprising episodes from The Sarah Jane Adventures as well as the animated adventures The Infinite Quest and Dreamland plus documentary 12 Again - in the run-up to the broadcast of Deep Breath that evening.
The show will also be available to TV licence-payers in the UK for a limited time via the BBC iPlayer.
As part of its celebration of the new series of Doctor Who, the Blue Peter website also has details about how to make Doctor Who character masks as well as Doctor Who T-shirts, and is inviting people to invent a new Doctor Who character.
