The Penguin is one of the only peaceful mobs in the game, along the rabbit and the firefly. They only spawn in the winter. They have similar mechanics to rabbits, as they run away from the player when they get close. The penguin feather is a drop unique to the penguin. It can be used to craft a pirate hat, sled, winter hood, the wand of death and the winter peasant's tunic
Cornering them into a tree or another obstacle is the most efficient way to kill them.
When farming for feather, players must at least have two available inventory slots as the raw meat will be prioritized over the feather.
The penguin was added in the "Faster" update.
