This mod adds Muddy Pig from Minecraft Earth into Minecraft Java Edition.
Muddy Pigs will spawn in River and Swamp biomes in groups of 2-6. You can breed them with carrots. It will also follow you if you hold a carrot or a carrot on a stick in your hand.
They drop Muddy Porkchops, which restores 3 food (as much as a normal porkchop), but also gives you the poison effect! To get rid of the mud on it, you need to combine it with a water bucket in a crafting table.
You can use this mod in modpacks, as long as a link to the mod's curseforge page is provided!
