Frank

Frank is a character that is the leader of the bullies. He beats on everyone and at one point in time he even shoots spit balls at Lisa. Lisa completely changed from being a more or less nice girl to a gang-member. She becomes Frank's friend and the friend of most of the gang. She is a dynamic character because she changes. I believe that this change is for the better because before she didn't really have fun talking and gossiping with all the other girls. Now she is enjoying herself by throwing snowballs at other boys. So, she is having much more fun which is good for a kid her age.
