This is a mod for a modpack called Mowzie's Mobs that will add compatibility for Mutant Monsters. It will include changing the mutant zombie model to geckolib, making it easy to modify the animations and model with Kube.js or resource packs.

This is for a very complicated and disorganized modpack that's hard to understand; it probably won't work in your own modpack. If you manage to figure it out, I'd be happy to let you use it in your modpack.
