"You have just opened a book about boobies. Meet the Blue-footed Booby, who does not have any boobies at all, since only mammals have boobies. We learn that mammals have boobies to feed babies, even though milk can also come from plants. And did you know that boobies, or breasts, vary from person to person, that boobies change over time, and that different animals have different numbers of boobies? Witty and wide-ranging, this eye-opening picture book goes on to explore connections between boobies and mountains, boobies and ancient art and, of course, boobies and you!"--Provided by publisher.
