Some of these things described as "weirder" really aren't. For example, Pinocchio burning his feet off and getting them replaced by Gepetto - this is a comical example of things implied by the story premise.

We have a child carved of wood, a flesh and blood child burns off their feet is a tragedy, but carved of wood we make new feet, hah hah!

Not saying this particular incident is to be expected exactly, but events of this type are to be expected from any competent writer who has taken up the premise. Especially as it is structured as a picaresque fairy tale, it would be weird if this kind of thing didn't happen.

Also - The fairy, originally a corpse - why is a dead revenant of some sort bringing a puppet to life any weirder than a magical fairy? That's not weirder, just different than we've been told.
