The Books of Canaan

Canaan is reading Fox in Socks, which he calls his "book of puddle paddle battle". All books are referred to by what is in them, not by the title-it sounds like some odd Biblical spin-off where all the apostles are scenes or inanimate objects. We have the Book of Backhoe, the Book of Thomas (the tank engine) the Book of Feet, the Book of "brush and brush the teeth" and the Book of Many, Many Animals.
