Just a quick look at Joy, the spirit of whom comes to me at times, and her mother. For some reason she grew only to "runt" size, no bigger than a typical Betaqh woman. But Joy is of the Taqh species and should be huge, like her mother. In the story about this, she goes in for "genetic engineering" which allows her to grow. She grows to tremendous size, bigger than her mother, so that a way must be found to reverse it a little so that she is not freakishly big either.
I don't think Shasheerians really have genetic engineering. It is a story based on a story from Shasheer for Shasheerians; that is, a kind of a "science fiction" flick of theirs.
Joy and her mom are farmers and live way in the wilderness of the mountains. Deep in the wilderness they discovered an unused, abandoned house. They live in it sometimes just for kicks. It is way up in the cliffs.See the next picture (click).
