Moon is Earth's best friend. She always hangs out with Earth, and is always by her side. Moon worries about Earth, because she's sick. There are tiny creatures on Earth that she calls humans. They do things like fight each other, build buildings, chop down trees, and other things. There are other creatures that live on Earth, but they don't hurt her (but the humans do, and they're why she's sick). Despite this, Earth cares for the humans and creatures, so Moon tries to not bring it up too much.
