Rock, rattle, and crawl along with the Fisher-Price Play & Crawl Hedgehog Mirror. This adorable roll-along hedgehog starts as a tummy-time toy for your baby, with a friendly face to gaze at on the large mirror. When your baby starts to sit up, they can explore the bat-at roller, clacker bead bar, and soft "quills" of their hedgehog pal. And when they're ready to move, give the hedgehog mirror a gentle push to send it rolling along, encouraging your baby to crawl and chase after it! Where development comes into play.
