The girl who asks: 'What are your names?'

I really think this is one of the most under appreciated characters in the film - the little girl who says "What are your names?" after the big fight at the pizza parlor. The way she delivers her line is just masterful and you can tell she really worked hard to get it just right. I was expecting, actually, for that character to be fleshed out for the rest of the film, perhaps as a sidekick to the 3 Ninjas.

Does anyone know who this talented young actress is? I can't believe she hasn't risen to Angelina Jolie level stardom by now. People just don't know quality when they see it.
