When Blue Peter teamed up with the Doctor Who production crew once again, viewers got the chance to design gadgets used by Madame Vastra, Jenny Flint, and Strax – better known as the Paternoster Gang – for Series 8. The judging panel included showrunner, Steven Moffat; designer, Michael Pickwoad; brand manager, Edward Russell; and CBBC presenter, Chris Johnson.

Doctor Who Magazine writers might recognise Chris as being part of their regular Time Team feature – and to prove his credentials on Blue Peter, he proudly wore our Seventh Doctor Jumper! Sadly, he didn't accompany it with the Seventh Doctor Hanky, or Silk Paisley Scarf.

Chris was on hand during the magazine show's 50^th anniversary party, in which Matt Smith answered a few viewers' questions, and the team created Dalek cupcakes. The eventual winners were Connor (13) from Somerset, Arthur (11) from Hampshire, and Amber (7) from Kent, who designed a Sonic Gauntlet for Jenny, Sonic Lorgnette for Strax, and Sonic Hat Pin for Vastra, respectively.

These all appeared in Peter Capaldi's debut episode, Deep Breath.
