I know at a different point in time they talked about it as well, but having trouble locating it; if memory serves, it was with the other stuff I was talking about. A lot of cool facts about Pokemon aren't readily available, being only talked about in Japanese Media - and a lot of that is obscure as well. I hope one day somebody translates the previously semi-canon
lore books by Takeshi Shudo; along with a lot of other obscure content.
