Did you know that clouds are alive, too?

New clouds are born each day, and old ones die. Like humans. On average, they live about a day, maybe a day and a half. During their short lifespan, the float around slowly and leisurely, all going in a single direction. They like to combine with each other, making a larger version of themselves. When they sun themselves like this, they cast dark shadows upon the strange land beneath them. The mischievous puffballs will piss on moving things on the strange land.

White flying machines will often invade the sky, and clouds will defend themselves by forming a billow of themselves. As hard as they try, they end up separating, giggling from the tickle of the propellers.
