The Boroboroton belongs to a specific group of yōkai: the Tsukumogamii. Tsukugami are various yōkai derived from manmade objects, such as kitchenware, tools and everyday accessories, that have become alive, either through possession by spirits or ghosts, or through constant use for at least 90 to 100 years. Boroboroton will come to life when feeling ignored or needless. As some kind of revenge (and out of frustration), they float through the rooms of inhabited houses at night and try to strangle any sleeping person they can find.
