Duck sees a bike and gets a wild idea–to ride it! But he's never seen a duck on a bike. Have you? At first, he wobbles a bit, but then...he rides fast past Cow, who thinks it’s the silliest thing she’s ever seen, and past Sheep, who thinks he’d better be careful. He rides past all of his animal friends and shows that following his wild idea leads to a great ride. Just because it’s never been done before doesn’t mean it can’t be done.
