Take it from my three-year-old son, this 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 pullback windup! All aboard for giggles and grand railway adventure! For ages 3 and up. (CH)
