Lavender Hair - Randy Cunningham: 9th Grade Ninja

Character meant to be depicted as 18 years old and older.

Simply known as "Nameless Girl with Lavender Hair" on the Randy Cunningham wiki. You can try adding "buck tooth, pointy ears" for more accuracy, but actually, it'll probably mess up your image more. "Pointy ears" is merely how the trainer tagged it. Not me.
