Indeed. The variety would be quite refreshing. And besides, people drawing more of them means they wouldn't be as rare anymore. Even getting abused, as that'd imply there's more of them out there, and taking it in context, given how much yukkuri reproduce there's a fair chance that adults featured might already have had a few litters of offspring. Personally, I don't view there being any rare or near extinct types because of their insane reproduction rates. They're just not depicted as much.
Of course, I guess that as long as there is an human to draw a specific yukkuri, then this kind of yukkuri isn't extinct. Which means that yukkuri will never extinct and that you can continue to draw them suffering for all eternity...
Seriously, this is depressing, even though they're only drawings on paper.
