Gavo are small, porcupine-like creatures from outer space. Their quills perpetually burn red-hot, which protects them from almost every predator, and their claws are perfectly evolved for digging through almost any material, which has enabled gavos to largely own the underground. Interestingly enough, it seems that gavos significantly grow in size when exposed to the sun, yet most gavos spend every free moment burrowing deeper and deeper into the planet. It is unclear what gavos eat for sustenance. Although gavos are solitary creatures, they are capable of reproducing in large numbers extremely fast if they encounter another gavo underground.
