Background
It is currently unknown how the bikers were formed, but at one point, Butchy, Lela, CheeChee, Lugnut, Struts, and various other teenagers joined together to make "The Rodents". It's also unknown why they began to have a rivalry with the surfers, but it's likely that it's because of their desire for Big Momma's.
History
In the original Wet Side Story, Butchy's younger sister, Lela, falls in love with the head of the surfers, Tanner, and they have to keep their love a secret.
