Piglin

Piglins are pig-like mobs that live in the Nether and absolutely love gold. Wear gold armor around them and they'll usually leave you alone.

Bartering

Toss a Piglin a Gold Ingot and it will "barter" — dropping a random item in return, like flint and steel, ender pearls, or even enchanted gear!

If you're not wearing any gold, Piglins will attack you.
Piglins get scared and run away from the Zombified Piglin's cousin: the Wither... and from zombies in general!
They love to dance when music plays nearby from a jukebox.

Fun Fact: Piglins turn into Zombified Piglins if they spend too long outside the Nether!
