Animated Horror

I have never seen an animated horror film,but I'd like to.That would be kinda sick if they did.I mean,there is the whole Creepshow thing but it's not totally animated.They should make one thats all cartoon.I know there's animated porn,but I havent seen none of that either(Id like too though,hee hee hee)

Some good manga/anime horror from japan, like Ichi the killer and I think the Story of Ricki was an animation and comic book originally.

Ive also seen some excellent Clive Barker Graphic Novels but I cant think of any other animations , anyone know of any?

Urotsukidoji is a good Manga horror film.
