Oh man, everything here is so adorable, including that water rocket Marisa. I like it when artists make yukkuris cute even while being abused: cuteness is the reason I dig yukkuri stuff in the first place.
The yukkuris on the top left seem to be enjoying warm air from air-com exhaust. Which would mean it's summer... wouldn't it be too hot?
Ha, the air-con exhaust gave me some ideas for abusing bad-mannered pet yukkuris.
Keep the room hot, they'll whine about the heat. Offer to make it cool just for them and not for the other nicehead yukkuris, which they'll accept. Put them in a fridge, they won't die as long as the temperature is above zero but they won't take it easy because it feels like mister winter. Take them out, leave them to warm up again, then switch on the air-con. They'll think mister winter is coming again, so they'll whine. Now offer them to put them somewhere warm, and again only them. Put them in a shut glass container outside in front of the air-con exhaust, get back in and enjoy the cool air with the niceheads who didn't whine. A total win.
