Even at smallfat level they just can't exist very well in the world without life support. That's one of the things that it's hard to wrap my head around. I mean they can't even do much outdoors through most of the year. Weather drops below freezing and their lack of balance and weird weight distribution gets them. Weather gets anywhere close to the triple digits and they turn into a sweaty panting mess. Hell, most of them aren't that great with muddy terrain either. Which even makes spring rough. So they're basically just eating themselves out of the vast majority of climates they're going to encounter over any given year.  And they don't see anything wrong with it! That's what just seems insane to me. You'd think needing technology to even exist would be a warning sign. But they need climate control as an ever present reality just to stay semi-functional.
