The Hybrid (Illager and Piglin Combo)

1.) The Hybrid

The Hybrid would be a mash up between an Illager and a Piglin, (has a zombified variant as well)
These creatures would live far away from anything normal, so they either go to the highest of heights, and live in the tops of snowy mountains, borrowing into the side of it to have a home. This creature could also be found in the bottom of jungles, hidden away.

These creatures would only be in packs of 2 or 3. They are default aggro, but can be passified if a healing potion is thrown onto it. These creatures would have the new ability to convert materials into other materials, sort of like alchemy. You throw the material at it, and then it goes to it's work station, being an at-the-moment unusable Alchemy Table (You need certain materials to activate it, such as dragon's breath, crying obsidian, and a totem of undying) It will throw back another material.

This process of material exchange using this creature is highly randomized, and unknown. Sometimes, the material you throw at it doesn't even work, in the case that the creature can't convert this material, it'll give you charcoal instead. There is only certain materials that this creature would accept. And this mechanic is also based on how much of the material you gave to the creature. Like bone mealing a sapling, sometimes requires more of one item to get something good.
