Saurian Swinoid are a type of (suprisingly intelligent) strange pig-like animal native to the Borkt Home Planet.
When the Borkt established a Mining Facility on Epsilon Gorniar II, they brought a herd of swinoids with them for food purposes. When the miners were wiped out, it appears their livestock escaped and acclimated to the world.
Jason Nesmith fought one before being attacked by the Gorignak, indeed he mistook it for Gorignak. To test the Digital Conveyor, it was used on the pig lizard before Jason Nesmith. The digitized animal upon its arrival was turned inside out and then almost immediately exploded.
