It'd be funny if Yukkuri were like turtles, and had difficulty righting themselves when flipped upside-down. Will their braids be strong enough to push them back over? Or will they in their stupidity push evenly with both braids and not get anywhere?
In the "A Village in the Forest" Series, yukkuris were flipped upside-down and weren't able to return to normal, though they also got their feet skewered, so maybe that's why they couldn't flip back, though maybe it's pretty much them being dumb enough to not use the weight of their sides to flip back? and it's not like they couldn't, after all stretch-stretch and other similar activities hint their capacity to move their bodies without bouncing or crawling to some degree, so they should be able, in theory to do like the turtles.
