Overview
Gruncau (also referred to as "cave cows" or simply "cau") are entirely found within Subminian territory in Gruncau Ranches and act as the primary source of meat for a Subminian society. They are favored for cave life due to their natural behavior of little movement and lots of eating. They feed off of grass that spawns from the underwater springs combined with the underground city's light output.
