The Poggers (singular pog) are neutral Mobs exclusive to the Hamlet DLC. These curious and hungry critters tend to spawn in small herds in the Wild PlainsBiomes. A pog drops a single Morsel when killed.
They are considered innocent creatures and killing one adds 2 points to the player's Naughtiness level, which can cause Krampus to appear.
They will also attack small creatures in the world like Butterflies, Glowflies, Pikos or Peagawks, and eat their edible loot, leaving anything non-edible behind for the player to collect.
The player may feed them any food item to make them a companion for a short amount of time. This can be helpful as they will fight aggressive mobs, distracting them and even defeating smaller mobs such as Rabid Beetles, Weevoles, and Poison Dartfrogs. A befriended Pog will follow the player into buildings and beg at food displays in Pig Shops.
If brought back to a base, Poggers, like Splumonkeys, will open Chests, Ice Boxes, Scaled Chests and Root Trunks, throwing aside items in search of food. They will eat any kind of food they find. They cannot open Cork Barrels, however, and if the player cooks items in a Crock Pot, a Pog will be distracted from ransacking the base for a period of time, but the best way to stop this behavior is to lead them away from the base or kill them.
During the Aporkalypse, Poggers will turn aggressive towards the player and all other mobs excluding their own kind. In addition, they can no longer be befriended by the player while in this state.
According to Wickerbottom, the scientific name of the Pog is Otocyon Canis. This breaks the rules of the binomial nomenclature, as it is a combination of two genera. The Otocyon genus refers to the bat-eared fox, whereas Canis is the genus containing dogs, wolves, etc.
According to Rhymes with Play #213, the word "Pog" is not a portmanteau for anything.
Because of the name resemblance and the similar color scheme, it's possible that Pog is a reference to the Porgs of the Star Wars universe.
During the Closed Beta phase of Hamlet, a Pog used to drop a Meat.
When left in an underground area for some time (such as the Ancient Pig Ruins), Poggers obtain their Aporkalypse look without turning aggressive towards the player or other mobs. It's unclear whether this is a bug or not.
