The Tube Foxes appear as eight scarred foxes wearing colored hoods with crests resembling an ink-brush. When defeated they turn into a purple orb of foxfire.
Together they form the Fox Rods which appears as a bundle of bamboo and is the source of Ninetails power. Each of Ninetails tails can become a miniature person, each wearing one of the Tube Foxes hoods.
People called kitsune-tsukai and kitsune-mochi are believed to take good care of and bribe kitsune with their favorite foods (aburage & azuki mochi) in return for magical powers. Even in modern times tsukimono-suji (hereditary witches) are feared for their reputations and the foxes they keep.
