Ravensburger's popular What? Why? How? The 12th volume of his children's book series guides preschoolers and elementary school children into the world of animal puppies. Among the mammals, you can get to know the lives of lions, giraffes, elephants, chimpanzees, kangaroos, bears, penguins and dolphins. They can learn how mammals, crocodiles, snakes, frogs and birds are born, how their parents raise them, and how they learn to thrive independently in life. The book also shows how small animals living in water, caves, underground cavities or even in our garden live.
