Biography
Willie worked as Groundskeeper at the Springfield Elementary since the school opened. This was due to his love of doing yard work. He loved doing yard work so much that he would spend his breaks mowing the lawn. However, when the apocalypse began, he was made unable to mow the lawn due to his lawnmower not working, and the grass dying due to the toxins in the air. This gave Willie the motivation to lead a rebellion against Zomer. He and Bart Simpson set traps at key places where "The Stans Of Mr. Burns" would meet up. He would later track down Zomer Simpson and kill him. After that, he and Bart would blow up all the bombs. After he won the battle against Zomer and Burns, he would marry Mrs. Edna Krabapple and adopt Bart Simpson.
