Snake style Kung Fu

Hey, everyone.
I’m kind of new to Kung Fu (I’ve only been doing Wah Lum for one semester), so I don’t really know too much about it.

I was wondering, is Snake style Kung Fu an actual style or system by itself? Or is it more like a part of a larger system, like Five Animals Kung Fu. Do people actually teach Snake style only? Because I just got DOA3 for the xbox and one of the characters does something called “She Quan”. I was curious as to wehether such a style actually existed, or if it was just something made up for the game.

Thanks.
