VTech Pop & Sing Animal Train Battery Operated. The VTech Pop & Sing Animal Train is a delightful battery-operated toy that combines music, lights, and interactive play to engage toddlers. Crawlers can push the train to hear fun songs and see the smokestack light up, while little ones can explore wheel switches that make animals pop up in a peek-a-boo game. Pulling the train encourages early walking and gross motor skill development, with a convenient pull cord that stores neatly under the train when not in use.
