livingbactery
Living Bactery is a Forge mod that adds a self-spreading swarm of worm-like microbes which consume blocks around them.
What it does
The swarm starts small and multiplies as it eats. Worm-like microbes devour dirt, stone and oceans, and blocks they reach vanish within seconds. The mod is meant for players who want a world-eating threat, and it is only summoned by a specific action rather than appearing on its own.
Sunlight stops the microbes from spreading and slowly burns them away, so darkness is where they thrive. Because the swarm consumes terrain, the mod suits players who run a separate backup of their world before releasing it. The mod is labeled a beta version, and the author warns to expect bugs.
The mod runs on Forge for 1.20.6 only, with a single 1.0.0 file in the beta channel published on 2025-11-04. Both the server and every player need it, since the environment is client and server. The code is not open source and is licensed as All rights reserved.
Key features
Self-spreading swarm
The microbes multiply and spread from a small start, so one release can grow across a whole world.
Block consumption
Dirt, stone and ocean blocks in the swarm's path vanish within seconds as the microbes feed.
Sunlight weakness
Sunlight halts the spread and gradually destroys the microbes, while dark areas give them room to grow.
Summoning requirement
The swarm only appears when it is summoned through a specific action, so it does not occur on its own.

Tiny. Fast. Hungry. The Living Bactery may be small, but don’t underestimate it — once released, it spreads like wildfire. These worm-like microbes devour everything, from dirt and stone to oceans themselves. Blocks vanish in seconds as the swarm grows, multiplies, and consumes the world around it. a weakness: light…
