An extension of the Groovy Tube Book line, this series engages younger kids with a fictional story that explores the book's topic while educating them with age-appropriate facts. With an illustrated storybook, ten toys, fun facts, and interesting photographs, Junior Groovies bring the fun of the Groovy Tube books to a whole new age group! Sturdy, foam-lined pages and chunky toys make these perfect for hours of imaginative play! From the engine up front to the caboose in the back, the freight train rumbles down the track. Kids learn about all the different cars on a freight train as they read this bouncing rhyme!
