Snail Mob
You crushed his wife. Now Jeffery is coming for you. The moment you spawned into this world, your boot came down on a small, fragile creature named Jeffica. You didn't notice. You walked on. Her husband noticed. Jeffery is a snail. Jeffery is slow. Jeffery is inevitable. He has crossed mountains for you. He has swum oceans for you. He has followed you into the Nether and out the other side. He moves at half a block per second. He will never stop. He will never sleep. And if he ever — ever — catches up to you, the message in chat will read: Jeffery got his revenge on you while you were trying to escape Skeleton.
How the Snail Mob Works
When you join a world, Jeffery spawns just out of sight and begins his slow, deliberate march toward your exact coordinates. He doesn't path around obstacles the way other mobs do — he is bound to you. Build walls. Dig holes. Sail away. He's still coming. If you outrun him by enough blocks, he enters a dormant simulation mode — the chunks around him unload, but his position continues advancing toward you in the background. The moment you slow down, or sleep, or build a base… he closes the gap. When he touches you, you die. There is no fighting him. There is no negotiating. There is only running.
For players who want a seamless setup, the foxygame.net launcher offers a one-click install for Snail Mob, bundling the mod with the correct NeoForge version so you can jump straight into the chase without wrestling with configuration files.
Items and Blocks to Track Jeffery
You are not entirely defenseless — you just can't win. You can only stay informed. The Snail Mob add-on provides a suite of tracking tools to help you monitor the inevitable approach.
- Snail Locator — A compass that points to Jeffery's current position. The needle never lies.
- Snail Sensor — A Geiger-counter-style detector that clicks faster as he gets closer. Silent at long range; frantic when he's outside your door.
- Snail Tracking Map — A map item with a live decoration that follows Jeffery across the world.
- Snail Beacon — A placed block that fires a vertical beam of light from Jeffery's position — but only when he's within 100 blocks (configurable). An early-warning system for the inevitable.
- Jeffica's Remains — The flattened shell of his wife. Dropped at world spawn. A keepsake. A reminder.
Configuration Options for Snail Mob for Minecraft
Everything is tunable from the in-game config screen (also hot-reloads from the .toml file with no restart). The Snail Mob for Minecraft experience is fully customizable to match your preferred level of dread.
- Snail speed — Default 0.5 blocks/sec. Crank to 5 for nightmare mode, or down to a crawl for a slow-burn campaign.
- Initial spawn distance — How far away Jeffery starts on a fresh world.
- Dormancy threshold — Distance at which Jeffery enters simulated pursuit (saves performance).
- Creative immunity — Toggle whether creative/spectator players are safe (default: yes).
- Distance broadcast messages — Periodic "the snail is X blocks away" chat messages. Disable for a stealthier, more terrifying experience.
- Sensor click ranges and rates — Full control over how loud and how soon the Snail Sensor reacts.
- Beacon beam visibility range — Radius around the beacon within which Jeffery's beam appears.
- Master enable/disable — Turn the entire mod off without uninstalling. All snails despawn cleanly.

The Inescapable Hunt
Jeffery persists through death, sleep, world reload, dimension change, and chunk unload. He is permanent. Each player gets their own Jeffery. He is your snail. He is hunting you. This is a beta release. If Jeffery does something especially memorable to you, send us an email at krookedlilly@gmail.com. All that's left of Jeffica… If you enjoy this mod, please check out our other games and apps at KrookedLilly.com.
The true horror of Snail Mob is not the speed — it's the certainty. You can build a fortress, sail across the ocean, or hide in the deepest cave, but Jeffery's slow, steady march never ends. Every block you place is a temporary delay. Every night you sleep is a risk. The constant ticking of the Snail Sensor in your base is a reminder that time is running out. This add-on transforms Minecraft from a sandbox of creation into a survival horror experience where the only goal is to keep moving. Whether you play for ten minutes or ten hours, the question is always the same: how far can you run before he finally catches you?
