IS-0173, more commonly known as the Pest is a hostile creature found in the Facilities that is originally from Anteverse II. It is a rather small creature, taking the shape of a spiked potato or bread loaf, and is the most common creature encountered. It prefers to hide in various nooks and corners to ambush it's prey, be it under desks, in vents, or behind boxes.
It is believed to be the second evolution stage of the Carbuncle, with it eventually evolving into the dog-like hunter known as the Peccary.
Pests can be trapped and tamed using a Pest Trap and 3 Nachos or Anteverse Wheat. Afterwards it will become friendly and can be ordered to follow you as a companion or randomly patrol. It will attack anything hostile to the player.
Tamed Pests can also be ordered to return to their cage or to generate power in a Pest Wheel.
