Moss, Lava

A type of red moss that only grows on rocks. In its native habitat, it grows extremely close to, and sometimes almost touching, lava in the planet's core. It can be safely transplanted anywhere else, even to frozen areas, and it will still grow just fine. It glows a firey red, but doesn't illuminate anything.
A sample of xenon moss was acquired by the unnamed robot after being taught about it by Cherry. It is now growing in the Slave Hole and Mushroom Apartments on Daenc Hydrax 4.
