The Zombie Pigman Addon adds zombie pigman into your world. As you know in new Nether Update they are gun. If you would like to see them back, for you this addon. You will see also Zombified Piglins
How does it work?
In Nether Update mob Zombie Pigman was replaced for Zombified Piglins. This addon adds zombie pigman but also will not delete Zombified Piglins. You will see baby of zombie pigman as well.
