Children will delight in sending this little toy rolling off again and again! It's delightfully simple to set in motion: Just push down on the center ball to flatten the inchworm, then let it go--the wheels spring into motion as the center "inches" up again. The rubber treads roll smoothly on almost any surface--babies and toddlers will love seeing it zoom from room to room as they crawl or toddle behind, building muscle strength and gross motor skills as they play. Bright colors, rattling wheels, a click-and-turn plush head, and a shake-and-squeak plush tail engage other senses, too, encouraging young children to explore first concepts, build developmental skills, and have a wonderful time playing with this sweet, smiley inchworm. Melissa & Doug K's Kids toys nurture early childhood development in three key skill areas: physical, cognitive, and social.
