Overview
Alex's Mobs is a large content mod that adds over 100 brand-new creatures to Minecraft, each with its own custom AI, models, animations, sounds, drops, and gameplay purpose. Instead of generic re-skins, every animal behaves like the real thing - grizzly bears fish in rivers, gorillas beat their chests, orcas hunt in pods, and roadrunners zip across the desert faster than you can sprint.
Beyond ordinary wildlife, the mod adds a roster of fantastical bosses - the Void Worm, Cachalot Whale, Warped Toad, Bunfungus, Cosmaw, and Laviathan - that drop powerful unique items.
Every creature comes with its own ecosystem of content: special foods, weapons, tools, armor, and blocks you can only obtain by interacting with that animal. An in-game Animal Dictionary guidebook documents all of it, and almost every spawn rule is configurable.
Alex's Mobs is a content-only mod and requires the Citadel library to load. See the Citadel wiki.
