This September we've been celebrating the Sontarans as part of Monster Month. And we have another EXCLUSIVE wallpaper for mobile and desktop.
This time it’s the turn of everyone's favourite potato-headed friend of the Doctor, Strax. He first appeared in the Eleventh Doctor episode, A Good Man Goes To War, and has frequently returned to help out with his buddies in the Paternoster Gang, Jenny and Vastra - who are also featured in the wallpaper.
Check out the exclusive artwork by Stephen Byrne below.
