These little balls are great for babies all are animated by something a bullet a fish that moves in tt ball "bell effect" plastic noise against plastic one that makes a little rain tree the two non-transparent balls make noise when you turn them on themselves (clack, clack) and the last ball has a picture on the inside that spins whenever we rolled the ball or it manipulates. The baby. I keep developed many motor skills and learn now share by rolling the balls ... Frankly super playful workshop and pretty colors flashy enough for baby 6 months and continues to play differently with 3 months
