Ed originally planned to use a small Honda Bike for Rat Fink but needed four wheels so it wouldn't tip over. Instead he used a Cadillac electric-starter motor for power and put it all together on a small kart frame.
After Ed was done he chased some kids with it. It scared the kids so bad that he never got into it much after that.
The hand that Rat Fink holds open usually carrys a small policeman.
