A type of yukkuri. These are members of the main yukkuri species, at times modified by artificial selection at the Factory or breeders. Much as several canine races were severely altered during centuries of evolution, the short lifespan and high breeding rate of yukkuris, along with the pliability of their manju bodies, made it possible for yukkuri breeders to send lots of different captive-bred exemplars, mostly with characteristics that would be a death warrant in the wild, to Yukkuri Pet Shops.
