Pull these soft constructions vehicles back to get new skills rolling! The "rev up" mechanism inside each of these four construction vehicles (mixer, dump truck, loader, and crane) 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 rolling, grasping, and pulling back is great for developing motor skills and hand-eye coordination. A variety of colors, shapes and sizes, illustrated characters, and everyday themes inspire conversations, cognitive connections, and imaginative play! Built to last, the vehicles feature a removable wipe-clean wheelie insert and washable fabric surface.
