England has been having quite a bad winter this year, with snow continuing well into this month. That’s why I wouldn’t be surprised if Doctor Who landed his TARDIS somewhere in the UK and encountered this… a snow Dalek.
Thankfully, Davros didn’t create an actual snow Dalek. It’s just a harmless sculpture made by DeviantArtist E-The-Zombie and her sister Fezhead11, and it’s not even in the UK.
While a snow Dalek might want to exterminate you, the good news is that you can actually just pour warm water over it to put it out of commission. I suppose that’s easier than having to install staircases everywhere.
