I always found children's stories more sinister than that. Perhaps you need to read the original versions and not the Disney-fied ones. Little Red Riding Hood, for example was given bad directions by the wolf and ends up eaten. The Little Mermaid does not get her prince, Sleeping Beauty finds herself raped and the mother of 2 when she wakes, in the 1800's version Goldilocks gets ripped up and eaten by the bears, in Snow White she awakens not with a kiss but as the cart carrying her back to the prince jostles- leaving us to wonder what the Prince was gonna do with the dead body to start with, never mind the fact that Snow is about 8 years old in the tale, Rapunzel gets her hair chopped off and sent away to live as a beggar with her child.
So um, what stories were about friendly animals that you were wondering about?
