Land of Ooo

The Doctor's TARDIS once materialised in the Land of Ooo. The Twelfth Doctor exited the TARDIS and immediately stepped onto a hidden spring trap that launched him into the air.

Shortly after, the Doctor charged into a battle with various other individuals. (NOTVALID: New Adventures Await!)
