The gang drive in car number 7, The Bulletproof Bomb (also known as The Roaring Plenty), and are pint-sized characters, a reference to the Seven Dwarfs. In the very first episode, "See-Saw to Arkansas", they even disguise themselves as the Seven Dwarfs to escape from a policeman. Their usual method of improving the speed of their car is "getaway" power, which they achieve by extending their feet through the floor of the car and running, the same way Fred Flintstone accelerates his own prehistoric car.
