> Blue Fairy — first introduced as a literal child-corpse with turquoise hair

He may have run out of ideas and tried to fill in a story with a dark mood in mind (speculation). The thing is that this is not that uncommon in many fantasy novels. Anyone remembers "The Color of Her Panties" by Piers Anthony? I read it, it is very cheesy (also silly, in particular when you as target audience are, say, 10 years old or something like that) but not necessarily mega-creepy either. But then you also begin to wonder ... is it just "good fun" to pick such a title? But then it is not the only instance and you begin to find more oddities. Naturally this depends on the author; some authors never run into such issues, others run into such issues.

I only saw the Pinocchio cartoon, that anime-style animation, on TV. That version was harmless from what I remember. Never read the books, but I am not so surprised about books being darker. Anyone knows the Grimm brothers? They lived from 1785–1863 and 1786–1859 respectively. I clearly remember that some of those drawings were really dark. It's a bit like dark horror stories if you look at it today - here is a summary:

It starts with "There are some fairy tales that are just not meant for kids.".

Some of the pictures by Grimm or illustrators are quite scary, such as the bleeding or weeping out of eyes ... is gross. Possibly these were more for adults, or adults who did not care, such as Pinocchio - perhaps. A puppet that has a growing body part ... that in itself is already super-weird. Are we certain the nose was meant? Is Pinocchio ... a prison item???
