In Lamb-a-roo, a lamb is adopted by a kangaroo. The mother and baby lamb love each other very much, but the lamb wants so badly to be more like a kangaroo. He does everything he can think of to become more like his mother.
He finds some bed springs and is excited to finally be able to jump, but if he is more like a kangaroo, he is less like himself - his own true perfect self.
This beautifully illustrated story is about accepting and appreciating differences and about learning that you don't have to be like someone in order to love them completely.
