American standards for children's books, especially in more recent times, are very different from a lot of other places. We're steadily taking out creepy/scary/macabre things so that children have safe, clean books, shows, and movies. I'm not judging it one way or another, I'm just telling my experience-- I'm a teacher of small children and I clearly see it happening. When I was a child I didn't like creepy or gross things at all so it wouldn't really bother me personally.
