There's been a huge snowfall, and Dragon happily builds a snowman. He's quite taken by his creation, and decides he wants it to come and live in his house, where it'll be safe. It's a bit too toasty inside, though, so Dragon has to find a way to cool down the house enough to keep the snowdragon from melting. He finally does... but then it's too cold for Dragon, so Dragon has to install his inside, outside, and find a way to keep it warm. He eventually realizes he's completely reversed things, to no-one's advantage. Mailmouse comes by and explains to Dragon that he can still play outside with his snowdragon and when he gets cold he can go inside and warm up by the fire. Dragon returns his snowdragon to the nice frosty air, moves back inside his house, and everything is just right.
