What is a piglin?

A piglin is a semi-neutral mob that reqruies the player to wear a piece of gold armor so the piglins won't attack the player or the player can just bribe the piglin with gold so the player won't die. Also gold is what piglin's love, if the player has gold ingots they can give it to the piglins and the player can trade with the piglins with the gold. The trades from a piglin range from items that are utterly useless to really rare items that are hard to obtain.
