You shouldn't judge herby her appearance. Headbanging Susie is a very nice girl with a good heart. She is polite and kind and loves her guinea pigs very much (she only feeds them organic food).
Headbanging Susie has one great weakness, however. You might have already guessed: it's head banging. If her guinea pigs wouldn't object once in a while she would head bang from 7am to 11 pm NON STOP.
