Moon Orbs are rock-like beings that look almost like little moons, they were formed from asteroids combined with strange Gron particles, and they each have a gun that is their most prized possession. Most get their guns from The Company or some other dealer, but others make them from scratch. Moon orbs can fly in any direction, and do not need oxygen to breathe. In the center of their little core is a moonstone that is actually very valuable, and it's what keeps them alive. Moonstones are very valuable, and that is why the Moon Orbs have to go into hiding. Many people such as the Hellots hunt for Moon Orbs to sell their crystals to get some cash. There is only one current known place where the Moon Orbs are living, and it is in Gron Fresnells core.
The Moon Orbs follow a being known as the King Asteroid Orb. They follow him due to his excessive knowledge of the Pcg Universe, some say he is a god, but others just think he is a rock that has lived very long and knows a lot.
