What happened to 3 little pigs, Little Red Riding Hoods or Goldilocks and the Three Bears. This is amongst the funniest and scariest. Long live the fine line between educational and downright creepy. This could be the most disturbing children book you ever read.
I really doubt this would be as mainstream as Little Red Riding Hood. There is no comparison. This is probably for special interest children who have been through the same thing the character has.
Disturbing or educational some children's books teach really good lessons (of course translated in those types of stories for the kids to comprehend).
I will tell you the best ever childrens book money spinner MR MEN books big bucks were made with them mr stupid mr this mr that mr everything £1 each. There the sort of ideas you need to be looking at when making products.
It is education but really disturbing. But if I had any kids I would not let them come anywhere near the book.
