Helga is famous for beating up the other kids, her pink dress, and picking on Arnold constantly. Even though she is madly in love with him and carries a picture of him in a heart frame at all times. She is much to insecure to ever tell him.
Helga is the daughter of a crazy beeper sales man and a mom that seems to be drunk all the time.
She also has a best friend name Pheobe, who is very intelligent and lets Helga push her around.
Helga really needs to shave that unibrow.
