The three vehicles that are ready to roll into action are waiting behind the three doors. All you have to do is match the colored keys as they unlock the doors and then slide the door to open the garage, press the buttons to release the ramp and send the vehicles racing to the rescue. The game improves the fine motor skills and provides hours of play time to little ones. The pieces fit into the whole set that comes with a sturdy handle and can be carried wherever you want them to play.
