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.
