This interactive accordion-fold board book, featuring die-cut windows to peek through and flaps to lift on every page, invites beginning readers to ride along. All aboard! While reading a simple story about riding the subway, fold this book out to explore each car inside and out--and meet your favorite Sesame Street residents along the way, from Abby Cadabby to Elmo to The Count to Big Bird and more! Each page has a flap to lift for added seek-and-find fun, and the back sides of the pages feature a running landscape of the street up above, with plenty of fun objects to discover from A to Z.
