"Quack!" says Mama Duck, "That's the way to be! Do like a duck does. Do like me!" On their way to the river, Mama Duck and her ducklings are joined by a hairy-scary stranger. He can waddle like a duck and he can strut like a duck - but is he really just a big brown duck? Mama Duck is suspicious and decides to put him through his paces! Children will love the comical, keenly-observed illustrations and rhythmic repetitions of the language, in this witty tale of foiled disguise.
