Oswoc

Oswocs are large orange ungulatoids with a short and rounded snout the have a large hump in their back and are naturally fat. They are passive creatures. If one happens to be facehugged, it will produce a Xenomorph drone despite its quadrupedal stance, which would normally produce a strain of Runner; the reasons behind this are unknown (it is presumed to be simple game mechanics).

They live in herds of usually a dozen although massive herds of several hundred have been found wandering around. They appear to eat moss-like flora and other flora which explains their presence in the cave when the Xenomorph hive broke out.

They seem to be herded and used for food by the humans on the planet and can be found just about anywhere on their homeworld.

Scientists assume the oswoc was genetically engineered to be a food source because a creature with no sensory organs, essentially a fat lump of uselessness, could not survive in the wild. Another theory is that oswocs have survived through their fantastic ability of spontaneous generation.
