A cause and effect masterpiece that lets kids pound the balls and watch them go. Hammer in the morning. Hammer in the evening. Hammer at nap time. And snack time. Whenever. Toddlers will have a whacky time with the Whacky Ball Bench. The rolling balls hold children’s attention while they develop motor skills with each whack. It comes with three brightly coloured balls and a hammer that squeaks. Have some fun and hammer away!
