What goes around comes around in this farmyard tale about the contagiousness of kindness.
Hen gives Pig an unexpected present. "How kind!" says Pig. Pig is so touched, in fact, that he decides to do something kind too. So Pig gives Rabbit a gift. "How kind!" says Rabbit, who does something kind for Cow, who is kind to Cat, who wants to be kind in turn. Where will all of this kindness lead?
