Set includes Penguin Music Wobbler, Bell Rattle and Beaded Raindrops. With the Penguin Musical Wobbler, children can experience sound and delight in the penguins soothing tinkling sounds and waddle. Roll the rattle away from you and it loops right back a little like a boomerang, sounding bell inside. Turn this rain maker over and stimulate senses with vibrant trickling beads and soothing raindrop sounds.
