Zombie Boarmen: Augmenting Zombie Pigmen

Pigmen are hardly very dangerous. They are honestly fun to mess with. The give the nether a warm and safe feeling.
Alright, let’s throw that out the window. Add a 3 block tall, 1.5 block wide Zombie Boarmen. They have a brownish color of fur, with exposed flesh. They occasionally have a golden axe, or even sometimes duel wield these. They have 40 hit points, and have the equivalent of leather armpit of natural armor points. They run at the speed of a player’s sprint and they can jump 2 blocks high. They are automatically hostile and spawn rarely in the nether with 10-20 zombie Pigmen.They are attracted to nether portals. If you hit a zombie boarman, the regular zombie Pigmen will become hostile. If they are killed, they drop 1-3 gold blocks and 0-1 Golden compasses.
Golden Compasses: they point toward the closest Nether Fortress by default, however, crafting them with things like a blaze rod will make them point toward the nearest Nether Portal.
