The Boom City Racers Starter Pack includes a light and sound launcher and stunt set! When you hear your car rev and see the fireworks spark, your car is ready to be launched. Pull the rip cord to hear the fireworks sound effects and your Boom City Racer car will speed out of its launcher. The Starter pack comes with a stunt set including a ramp, target and 5 barrels to boom through! The Starter Pack comes with an exclusive "Hot Dawg!" car! The light and sound launcher works with all Boom City Racer cars in Series 1.
