The rev up mechanism inside each of these two vehicles (a school bus and a fire engine) makes it easy for babies and toddlers to get big acceleration with just a little input: Pull back one of the soft vehicles--then release to see it zoom off across the floor! The action of grasping and pulling back is great for fine motor skills and hand-eye coordination; the activity of driving and collecting (pull, release, crawl) benefits large muscle groups and coordination, too. Get even more skill-building miles per gallon with a variety of colors, illustrated characters, and everyday themes to inspire conversations, cognitive connections, and imaginative play!
