An indoor game played by two or more players with similiar rules to those of soccer. Some significant differences are that it is played indoors and has a cube-shaped poof/foot stool as the "ball", hence its title.

The encumbering nature of the poof/foot stool and surrounds adds a tremendous element of difficulty to an already skillful game. Although the poof/foot stool is often soft, injuries are still incurred.

Brendan: Oh God! My knee!
