From tiny zombies to giant chickens, every mob encounter becomes a unique surprise!

Important Note
While Random Mob Scaler can add fun and excitement to your survival server, please be aware that it may interfere with existing mob farms or game mechanics that rely on standard mob sizes.
It's recommended to test thoroughly on a backup world before using on your main server.
Use this plugin at your own risk, especially on established servers.
