From mountain to rocket ship, a small rabbit shows that a box will go as far as the imagination allows.Inspired by a memory of sitting in a box on her driveway with her sister, Antoinette Portis captures the thrill when pretend feels so real that it actually becomes real—when the imagination takes over inside a cardboard box, and through play, a child is transported to a world where anything is possible.After reading this book aloud, continue the fun by drawing shapes like a triangle or circle, and asking your child what the triangle is NOT!
