🌟 Huge thanks to Shcott21 who originally published this mod as the Mutant Creatures so many years ago. Most of the work and most of all the amazing models were all done by him.
🌟 Thanks to Chumbanotz for being the first to bring the mutants to modern Minecraft in the form of their Mutant Beasts mod, laying the ground work for this final revival.
🌟 Thanks a lot to tdstress for overhauling all textures in the mod to fit the new Minecraft art style!

Written by Fuzs. Read it with pictures on Modrinth.
This mod is needed on both the server and every player who joins.
Install Fabric, Forge and NeoForge for Minecraft 1.18 – 26.x.
Add the mods it needs: Forge Config API Port, Puzzles Lib and Fabric API.
Download the .jar file from Modrinth and put it in the mods folder of your .minecraft directory.
Start Minecraft with the Fabric profile.
Easier: in Prism Launcher or the Modrinth App, search for Mutant Monsters in your instance's mods and click Install. It adds the loader and the mods it needs for you.
