Quad-Fu is a long-forgotten and ancient art some estimate it to be up to eight-teen years old. Its basis is belief of the Cookieforce. It is generally best to practice it while playing music from the Water Temple.
All Quad-fu videos have been removed from YouTube by Quady due to hus disdain for much of his older content.
The main weapon in the Quad-Fu arsenal is the slipper. It is a powerful weapon; sadly its exact uses are at best vague. It is assumed that is is used as a blunt weapon much like a hammer though there is a strong possibility that there was a bladed version to combat swords and knives.
