The Musical Activity Walker is part of Fisher-Price's Brilliant Basics line of classic play toys designed to enrich a baby's development. With the Musical Activity Walker, babies can touch different areas on the toy to hear sounds and music. Play the colorful piano keys, flip the picture book page, turn the tambourine dial, spin the maraca, and press the saxophone. As babies learn to walk, they can stand and push the Musical Activity Walker to hear music play. http://www.timetoplaymag.com/toys/2446/fisher-price/musical-activity-walker/
