This is literally the coolest fucking thing I've seen so far this month. It's a dramatization of the classic "blood test scene" from John Carpenter's The Thing, but with the characters from Disney animated film Frozen using Play-Doh.
I would love to show this to my girls, but they're at an impressionable age and they come to me in the middle of the night when they wake up with nightmares. But soon...
This reminds me of that G.I. Joe version of The Thing that came out several years ago. I'll post the video below so you don't have to hunt around for it.
