The Linkimals™ Happy Shapes Hedgehog™ is packed with exciting play that grows along with your baby! Younger babies can spin, turn, toggle, and bat the activities on their buddy's back, or press the light-up buttons to hear songs and phrases about colors, shapes, and numbers. Then older babies can push or pull the hedgehog along for more fun music and sounds. Plus, when Happy Shapes Hedgehog™ recognizes other Linkimals™ friends, they create a synchronized music and light show! (Additional Linkimals™ toys sold separately.) Where development comes into play™ Early Academics: The hedgehog's playful songs and phrases introduce your baby to shapes, numbers, and colors. Gross Motor: From sitting up to play, to crawling and pushing, to walking and pulling their pal along, this sweet hedgehog helps your baby's gross motor skills keep going and growing! Fine Motor: Spinning the roller, turning the butterfly clicker, pressing the toggle, and batting the bead bar isn't just super fun; these activities help strengthen your baby's dexterity and hand-eye coordination.
