Ed originally planned to use a small Honda Bike for the Rat Fink Hot Rod, but found he needed four wheels to keep it from tipping over. He ended up using a Cadillac electric-starter motor for power, and put his Rat Fink Hot Rod all together on a small kart frame.
After Ed was done building the Rat Fink Hot Rod, he decided to chase some kids with it. Off he went to find some kids to scare, and find them he did, but it ended up scaring the kids so bad that Ed never drove the Rat Fink Hot Rod much after that.
The hand that Rat Fink holds open usually carries a small policeman.
