What do all those animals on the farm do when no one is looking?   The ducks in the pond swim and paddle all day. They dip-dive and swirl in fountains of spray. But when no-one's looking . . .   The animals on the farm can swim, stomp, and run. But when no one is looking, they have all kinds of fun! A charming lift-and-reveal picture book perfect for young children playing on the notion that animals are up to funny and often absurd activities when no one is looking.
