I have that book! The Melancholy Death of Oyster Boy...
I'd love to make a living out of writing slightly wrong fairy tales. I did think up a well good story about pigeons but I was knocked down by pretty much everyone because pigeons are dirty so it wasn't a good idea for kids to like them.
Well, I say, a t-rex could probably eat a toddler in one mouthful but no one complains about that! Bob the builder...kids and power tools? I think not.
