This is an illustration of a moment in the book The Secret Of Vault 13 by David Solomons. These creatures called Frost Lepuses, which are described as big bunny like creatures, come to pull along the TARDIS fam on sledges. Yaz reminisces about how she’d always wanted a pet bunny rabbit.
The Geode Lounge is the cosy room in the TARDIS where the 13th Doctor has her purple sofa. The hexagon inset shelves are smooth slices of Geode. There are warm hexagon shape lights set into the crystal Geode walls. Yes, this time it really is Ed Sheeran.
