Our stackable penguin is a real softy. We put a new spin on stackable toys. Our new design offers multiple textures and fanciful patterns on soft, squishable rings. Each ring offers a special play element like a crinkle sound, silly squeaker or riveting rattle. The lovable bird topper is so kid-friendly and makes a delightful giggle sound. And besides being such an entertaining toy, its great for hand-eye coordination. Its easy to see why our new stacker toy is tops! For babies 6+ months. Rings are easy for little hands to hold.
