A happy little duck floats inside a big, clear plastic ball as it rolls along, encouraging teenytiny ones to bat at and roll the ball – then crawl and chase after it as they grow. This floaty little friend really keeps the fun rolling, from newborn to toddler. It's just the right size for little hands to grasp, with colorful confetti that swirls around inside to entice baby to shake it up. Where development comes into playTM Fine Motor – Batat play, grasping & releasing, and shaking the ball all help strengthen baby's fine motor skills. Gross Motor – Crawling after the Watermates ball helps exercise developing gross motor skills.
