Minecraft wiki entry for Combat, associated text: If a hoglin enters the Overworld, it will become a zoglin, similar how a piglin transforms into a zombified piglin. Zoglins are hostile to every mob and players except creepers. Like hoglins, zoglins can attack and fling the player in the air. They drop Rotten Flesh upon death. Hoglins stay further away from zoglins if not engaged in combat. Zoglins are undead mobs, which can make the Smite enchantment very useful.
