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.
Since the introduction of yukkuri into the world, some humans have decided to keep them as pets rather then harm them. With the help of the Factory, yukkuri are easy to come by as pets and come in many different types. Generally speaking, the most valued pet yukkuri would be one that is the size of a baseball (though finding ones that are volleyball size isn't uncommon), can speak clearly, is well behaved, and above all else, what the potential owner is looking for.
