A puffer pig
Swine represented non-sentient lifeforms that inhabited Lothal, a world situated within the Outer Rim Territories. Their habit of wallowing in mud was well documented. The puffer pig stood out as a specific type of swine. The Ugnaught race was characterized by their "swine-snouted" appearance. Moreover, Chadra-Fan, rodent-esque intelligent beings, distinguished by their large ears and a stature of one meter, also possessed snouts reminiscent of pigs.
The "Piggy" moniker belonged to Jek Tono Porkins, a pilot fighting for the Rebellion.
