LEGO® DUPLO® My First Fire Helicopter and Police Car (10957) is a toddler-friendly, developmental toy built with colorful shapes and filled with fun features. Toddlers build skills as they enjoy hands-on fun with this push-along police car and fire-fighting helicopter. Basic construction tasks improve fine motor skills and teach toddlers about shapes and colors. Detailed decoration on both sides of the vehicles, a siren brick (no noise) and a propeller that can be spun all help to bring the imaginative play to life. Building cards, featuring life-size images of the models, let kids position the bricks over the image as they build.
