Creatures++ is a 1.12 command mod pack that adds 16 new biome specific mobs to make your survival experience more exciting! These mobs will replace some of the normal mobs that spawn (mostly zombies and skeletons) to make each biome feel more interesting. All of the mobs have their own custom drops and stats, and some of them even have their own special abilities.

Make sure to check out the new vision for 1.1.3! It has even more mobs! LINK: www.planetminecraft.com/project/creatures-2-0-for-minecraft1-13/
