From the award-winning author of Little Pea, Little Hoot, and Little Oink comes a clever take on the age-old optical illusion: is it a duck or a rabbit? Depends on how you look at it! Readers will find more than just Amy Krouse Rosenthal's signature humor here; there's also a subtle lesson for kids who don't know when to let go of an argument. Duck. Rabbit! is a New York Times best-selling children's book!
