The story starts off well but drags considerably halfway through and never recovers. The pacing is terrible. This probably would work better as a short story than as a picture book. The intended age group will never sit still for the length of this book unless they're reaaaally into dirty cowboys who run into problems bathing.
Also, as is implied on the front cover, there are many images of discrete nudity. We're not talking In The Night Kitchen full frontal or anything but if you're offended by such content, this probably isn't the book for you.
Rex's art is top notch, as usual.
