Meet the Blue-footed Booby - who does not have any boobies at all, because only mammals have boobies. Learn that mammals have boobies to feed babies; that boobies, or breasts, vary from person to person; that boobies change over time; that different animals have different numbers of boobies – and more. Witty and wide-ranging, this eye-opening picture book explores connections between boobies and mountains, boobies and ancient art and, of course, boobies and you!
