The one at the bottom left of the koyukkuri pyramid is clearly a Ran, not a Chen, but for some reason editing tags doesn't seem to work for me - it kicks me to the 'search timed out' error message.
Looking at that cute little pile of fluffy kos, I can almost understand why yukkuri want to refresh so much. I know that basic evolution would drive yukkuris that prefer easiness to reproduction to extinction, but really, Chen, this is going to be for the best for you - they're not going to be that cute all the time, they're mostly going to be whiny little balls of tears that shit everywhere.
