This Kullerbu white ambulance has a momentum motor that allows it to travel forward on its own. Simply give the car a push and watch it speed along the tracks or any hard surface! * White Ambulance measures 3.5" L x 2.2" W and is made of ABS plastic. Suitable for children ages 2 and up. * Kullerbu vehicles are just as much fun off the track and can be enjoyed as a stand-alone accessory * Designed for the Kullerbu Play Track System, the wheels rest on top of the tracks allowing it to travel along like a roller coaster. Please note: While Kullerbu vehicles are mostly compatible with the Kullerbu Play system, there are certain accessory pieces (such as the universal steep curve) that work only with Kullerbu balls and cannot accommodate Kullerbu vehicles. * For ages 2+ * All HABA toys are rigorously tested to meet US and European Federal safety standards.
