@vuelle it's an item called the dragon head stone it's transform your head into a dragon and let's you breath fire but you can't usse a helmet. but on the animation it's amazing. :)
it really looks like cuphead!
btw what the heCSH was that part when one of them took of their helmet and they had a dragonhead about? I don't play/watch dark souls.(0:43)
Gotta say it must be tough making Cuphead tributes that follow the source material. Props for that
