by mr-chibi

Mr_ChibisMMO Mobs gives servers a way to define custom mob variants that spawn naturally in the world, based on random chance, and it needs the Mr Chibi's MMO Datapack installed to work.

What it does

Custom mob types are built with a creation tool, and each one can be given its own attack damage, health, armor items and hand items. Once a variant is set up, it can appear in the world through natural spawning, with the spawn chance decided by a random roll.

The mod is a server-side addition: the server must run it, while players can join without installing anything. It requires the Mr Chibi's MMO Datapack to be installed. After the data is added, the reload command on vanilla servers or the minecraft:reload command on Paper applies the changes. A list of the customizable options can be viewed in-game to see every available setting.

Mr_ChibisMMO Mobs is published for Fabric, Forge, NeoForge and Quilt, and as a data pack for server platforms. Files target 1.21.4 – 26.1.2, with the latest build 26.1.2+mod for 26.1.2. The code is all rights reserved, so the mod is not open source. Source code, an issue tracker and a wiki are publicly linked.

Key features

  1. Custom mob creation tool

  2. Randomized natural spawns

    Custom variants appear in the world through natural spawning, governed by a random chance roll.

  3. Adjustable combat stats

    Attack damage and custom health can be set for each variant, shaping how a mob fights.

  4. Custom armor and hand items

    Armor items and hand items can be assigned to each variant, so mobs carry distinct equipment.

Use cases

Who it’s for: The mod suits server owners who want custom mobs with set combat stats and equipment, and who are prepared to install the required datapack and run the reload command after adding data.
