Mutant Addition Mod
by ohpang
Mutant Addition Mod adds colorful mutated mobs to the Minecraft world, and players can feed a skeleton a blue orchid to mutate it.
What it does
The mod adds a set of mutant mobs that appear in the world alongside the vanilla creatures. Players can encounter several colorful variants, and some of them are given mythical traits. Throwing a specific friendly mob at a hostile one can convert it, and befriending a mutant changes how it reacts to the player afterward. Some encounters only happen at night.
The mod lists Geckolib as a required dependency, so it must be installed alongside it on Forge for 1.20.1. Either side can run it, and neither needs it. Its mutations draw on the mutant-creature content of the Mutant Monsters family, and the author credits JujuStyle7 for permission to use models and animations from Bedrock Edition's Mutant Creatures.
The mod is published for Forge only, with 1.5.0 for 1.20.1 as the latest file, dated 2025-10-05. It was first published on 2025-03-25 and is released under the MIT License, but it is not open source.

How it compares
Old Mutant More is a Forge mod for 1.16.5 and is licensed as All rights reserved, so it does not match this mod's version. Red's Mutants and Mutants Plus are Forge mods for 1.20.1 under All rights reserved, and both run on client and server together. Mutant Skeleton Armor Tweaks is open source under the MIT License and also covers Fabric, but it changes skeleton armor rather than adding mutants.
