You remember the children's story Goodnight Moon, right? It's the one with the little who's going to bed, so he says good night to basically every single thing he lays eyes on? Well in this video, Link is the kid, and there's a whole lot of weird stuff in his room.
Personally, I don't know how Link could get to sleep there. Between the skull kid and the moon, I'd be having nightmares indefinitely.
