Harry Potter's Original Concept Art Might Give You Nightmares

Are you ready to enter Harry Potter: The Creature Vault? Warner Bros. and Harper Collins released a book last year featuring the astounding original concept art for many of the creepy-crawly (and cute and fluffy) creatures from the books. Now that October has rolled around — thus kicking off spooky season — we're revisiting some of the weirdest images from the book. I'm not going to say Fenrir Greyback isn't going to haunt your dreams, because he will. Take a look to see some of the first iterations of Voldemort's pet snake, Nagini, and the Dementors, and soothe your soul with the adorable Arnold the Pygmy Puff.
