Seven goats tale

Intro The Wolf and the Seven Little Goats. A fairytale by the Brothers Grimm. You are the wolf and you are trying to trick seven little goats into letting you into their little cottage so you can eat them. You start off by just going up to the door and saying "It's mummy" they dont belive you because you have a deep voice and black feet. Look up the rest of the story because I cant fit it all in here.
