Well they are yukkuris, not surprised they fail at realize how bodied shapes help them quite a lot, i mean, it's rare the cases of bodied yukkuris being abused or killed, unlike what happens with the average ones.
Again, that's yukkuri logic and we know how flawed their logic is.
Besides, lately i had been having serious doubts about their claims of easiness because of all the uneasiness they generate, hell sometimes they make humans look like the easy ones.
