This mod transforms your world into an unpredictable adventure where no mob is quite what you expect. Whether you’re chasing down a pint-sized skeleton or running from a gigantic baby zombie, the scale-shifting mechanic adds chaos, charm, and endless replayability. Built for both casual players and modded veterans, Random Mob Sizes Mod offers an easy-to-configure experience that blends seamlessly into vanilla gameplay while opening up space for experimentation, fun, and challenge.

FAQs

Do mob sizes affect health or damage?

By default, no. Mob stats remain unchanged unless another mod modifies them. Size is purely visual and behavioral.

Can I configure which mobs are affected?

Yes. The config files allow you to whitelist or blacklist specific mobs, and even set size ranges individually per entity.

Does it work with custom mobs from other mods?

In most cases, yes—especially if the custom mobs use standard Minecraft entity systems. Some compatibility may depend on the mod’s code structure.

Will this break mob AI or pathfinding?

No. The mod adjusts the hitbox and scale but retains the default AI and movement patterns of each mob.

How do I install Random Mob Sizes Mod?

Install Fabric, Forge, or NeoForge for your Minecraft version, then place the mod’s `.jar` file into the `mods` folder along with any required API (like Fabric API, if applicable).
