Dunno if they're shitheads or niceheads or whatnot, but the near-perfect roundness of the kos' bodies (heads?) and their tiny accessories just make me want to crush them so much. Sometimes, there's this urge in you to mutilate and absolutely destroy small and cute things like these guys.
Bonus: A crying wasa is a deathflag, not just for itself, but also for the other kids around it.
