The pig beast is a commonly spawning beast that can spawn in any biome. You will mostly see them in the Grasslands biome.
The pig beast has 2 drops: Leather and Meat and can drop around 3 items. The pig beast plays a part in two events, the "Rage of the Pig Beasts" event and the "UFO pig abduction" event. These beasts will not attack you unless the "Rage of the Pig Beasts" even is currently active. It could be possible that they can take more hits than an average beast.
