The Pig King can be found in one of the Pig Villages that generally spawn on a Grassland patch or in a Forest biome. He is usually laying on Wooden Flooring surrounded by Obelisks, and may be guarded by Guardian Pigs if playing in Adventure Mode. He is immune to any damage and cannot be attacked.
During the day, the player can make offerings to the Pig King in exchange for Gold Nuggets. At Night, the Pig King goes to sleep and cannot be traded with. He will not hold any grudge towards the player, even if they kill his fellow pigs or his Guardian Pigs.
In Adventure Mode, worlds may have different chances of encountering the Pig King based on the specific world's individual rules.
Exchange rates 
During the Hallowed Nights event in Don't Starve Together, the Pig King gives Halloween Candy in addition to Gold Nuggets. If the player is wearing a Halloween Costume Skin, the amount of Candy will be increased.
- Meat that is not accepted by the King can be converted into Eggs by a Bird in a Birdcage, and then offered to the King. This makes Gold Nuggets an infinite resource, as Meat is a renewable resource in the game.
- A low cost method of obtaining Gold from the Pig King would be to place Lureplants on turf, such as Rocky Turf or Wooden Flooring, where it can't spawn Eyeplants, and repeatedly harvest the bait.
- The Pig King will throw the Gold Nuggets towards the player's camera. Turning the camera will cause the Gold Nuggets to land in a different place.
- Humorously, the Pig King will refuse a haunting from a Ghost Character in Don't Starve Together.
- There is a Pig King Vignette in Don't Starve Together. Its flavor text provides a little background for the Pig King and his followers: "Legend has it the Pig King and his followers left their home long ago to rule freely in The Constant." Their previous home could possibly be the world of Hamlet.
- Depictions of the Pig King appear in the Hamlet DLC. For example, one of the Intricate Topiaries is shaped like him.
- Sometimes, a Pig King does not spawn in Sandbox Mode because there isn't enough space for his Set Piece to be created during the world generation.
