What does stargirl do? What are her actions in the story?

When Stargirl appears at Mica High she is in the 10th grade. To say that she is eccentric in dress and behavior is an understatement. Sometimes she dresses in costumes. Later, we discover that her mother works as a seamstress making costumes. Her "ordinary" apparel is a long dress, which is described as a "Pioneer" dress. She is first described as rather average-looking with long sandy-brown hair and freckles across her nose. Her distinguishing characteristic is her very large eyes. Stargirl carries a pet rat in a bag that is decorated with a large Sunflower. She also carries her Ukulele around, plays it and sings to people for their birthday. Through the author/narrator we begin to see a girl who is untouched by the pressure to conform. She seems more in tune with nature than people, and more able to feel the joy and sorrow of others with an unmatched intensity. This is clear when she cheers at football and basketball games, attends wakes, and shares the beauty she sees in her environment with Leo.
