The Treeline Watcher

A towering horror mob that hunts you at night and only moves when you look away.

The Hollow Stalker

Something tall is watching you from the treeline.

The Hollow Stalker is a horror mod for Minecraft 1.20.1 (Forge) that adds one terrifying creature: a ~4.3-block-tall, emaciated skeletal thing with very long arms, twitching clawed fingers, a pale skull and pin-prick eyes that glow in the dark.

It doesn't spawn in crowds. It picks one player, and it hunts them.


🌲 The Hunt

  • It chooses you. At night, or in dark caves below Y=50, it can start hunting you. It appears 35–55 blocks behind you.

  • It only moves when you aren't looking. Look at it and it freezes, tilts its head, and stares back.

  • Blink and it's gone. Stare too long and your screen flickers black. It vanishes… and shows up somewhere else.

  • It gets closer every time. Each encounter shrinks the distance it keeps from you.

  • The scream. When it's done stalking, when you get too close, or when you hit it, it throws its arms up and lets out a deafening shriek that can be heard up to 128 blocks away. Your camera shakes, Darkness falls, and then it sprints at you.

  • Long arms. It can hit you from almost 4 blocks away and smashes doors, glass, fence gates and leaves in its path. If it gets stuck, it simply appears right behind you.

  • There is no safe house. It opens wooden doors and folds itself down onto all fours to crawl through doorways, tunnels and low ceilings.

  • Sunlight drives it away while it's stalking. A hunt ends after about 70 seconds, after 6 hits, or once you get more than 72 blocks away.

😱 The Scares

  • Full-screen jumpscares — two different screaming skull faces, with a screech, screen shake and a red flash.

  • "Behind you" — it teleports right behind you and breathes on your neck. Turn around… or don't.

  • Lights out — your screen goes black, and when it comes back, it's standing in front of you.

  • Phantom footsteps walk up behind you. Whispers play right next to your ear.

  • Snuffed lights — torches, lanterns and campfires go out around you, but only the ones you aren't looking at.

  • Doors creak open on their own.

  • Creepy action-bar messages like "Don't turn around." and "I see you, <name>."

  • A heartbeat that speeds up as it gets closer, a dark vignette, closing-in fog and subtle camera sway.

  • You can't sleep while it's near.

  • Silent while stalking. Thunderous footsteps while chasing.

❓ FAQ

Is it Fabric / NeoForge / other versions? Not right now. Only Forge 1.20.1 is supported.

Can I use it in a modpack? Yes! The mod is MIT licensed. A link back to this page is appreciated.

Does it work in multiplayer? Yes. It hunts one player at a time. The mod must be installed on the server and on every client.

Will it destroy my base? It can break doors, glass, fence gates and leaves while chasing, and put out lights. Turn off mobGriefing or disable smashDoorsAndGlass / snuffLights in the config to prevent this.

It's too scary / too frequent! Lower spawnChancePerCheck, raise huntCooldownSeconds or minimumWorldDay, or turn off jumpscares.


⚠️ Warning: this mod contains loud sounds, sudden full-screen jumpscares, flashing red and black screens, and camera shake. Not recommended for players sensitive to flashing lights or jumpscares.

Don't turn around.
