The LEGO City Emergency Rescue Helicopter building set is designed for children ages 6 and up. It includes 199 pieces to construct a detailed rescue helicopter with spinning rotors, an opening cargo bay, and a working winch. The set also comes with three minifigures: a pilot, a hiker, and a rescuer, allowing kids to role-play emergency scenarios. An interactive digital guide is available through the LEGO Builder app, which provides 3D model viewing, progress tracking, and virtual set exploration. This set can be combined with other LEGO City playsets (sold separately) to expand play possibilities. LEGO City themes encourage imaginative building and storytelling with realistic structures, vehicles, and characters.
