Take it from my three-year-old son, our Busy Train Book is "hiwarious"! Each spread has a built-in train track—meandering through a village, a farm, and more—with engaging text about all the exciting sights on the way to the zoo. And the most super-fun part: a little train engine whizzes around each path with a simple pull-back wind-up! And for even more roadway hijinks, travel the city of London with our Wind-Up Bus Book…the pages even pull out and connect together in one big 23"x16½" map for the double-decker bus to traverse. For ages 3 and up. Each sold separately. (CH)
