1. Children cling immediately, history, repetitive, simple, yet innovative: it shows the subject of money, labor, the food chain, made affordable for children from 2 years! 2. The real treat, it is words. Children enjoy a lot, adults also. It is never quite repeated. It's full of humor and puns, of homophonies, winks. 3. The portion of horse manure is a fine example of a useful presence, motivated, feces in a children's story. No noticeable demagogy but no taboo either. We laughed heartily, frankly. And one can approach the usefulness of manure (the urban children often know only the scourge of dog mess on the pavement ...) 4. It is easy to stage for the adult reader, even if it's hard to be expressive in ordinary times. The effects of voices, the sound effects are needed, the child is enjoying it.
