Hammer in the morning. Hammer in the evening. Hammer at nap time. And snack time. Whenever. Toddlers will have a whacky time with the B. Whacky ball. The rolling balls hold children's attention while they develop motor skills with each whack. It comes with four brightly colored balls and a hammer that squeaks. A mirrored background adds to the action for loads of whacky fun. Ages 1 year and up.
