The fake Crazy Car Store worker is back and she is ruining all of the Wacky Car Store's cars! She wants all of the customers to herself so she test drives each of the Wacky Car Store's ride on vehicles and messes them all up. One by one, each Power Wheel car has to be taken to the repair shop. The fake store worker uses her silly string, paints, and off-roading skills to break each kid car.
