| Ceiling/Ambush | Drops from above | Snare Flea |
| Giant | Large outdoor threat | Forest Keeper |
Danger Ratings
| Rating | Meaning |
|---|---|
| 1-3 | Low threat, easy to avoid |

| 9-10 | Extreme threat, avoid at all costs |
Complete Entity Database
1. Bracken
Also known as: The Backrooms Monster, Neck-Snapper
The Bracken is a tall, humanoid entity with pale skin, no face, and a set of what appear to be ribs exposed on its back. It stalks players through the facility, retreating into shadows when spotted. If a player stares at it for too long, it will snap their neck in a instant-kill animation.
| Attribute | Detail |
|---|---|
| Danger Level | 9/10 |
| Spawn Locations | All moons, interior only |
| Detection Method | Line of sight within ~20 meters |
| Speed | Walks slowly, sprints when attacking |
| HP | 5 hits (shovel) |
| Can be Killed? | Yes, with 5 shovel hits or 2 shotgun blasts |
| Sound Cues | Loud breathing, rustling footsteps |
| First Appearance | v35 |
Behavioral Analysis:
- The Bracken patrols the facility interior, moving room to room.
- When it spots a player, it will raise its arms and back away slowly while maintaining eye contact.
- If the player maintains eye contact for approximately 3-4 seconds, the Bracken enters a rage state and instantly kills the player by snapping their neck.
- After a kill, the Bracken drags the body to a hiding spot.
- It retreats if you look at it and back away, but it will stalk you from adjacent rooms.
Counter-Strategy:
| Step | Action |
|---|---|
| 1 | Do not run. Running triggers chase behavior. |
| 2 | Look at the ground or turn away from the Bracken. |
| 3 | Back away slowly while looking away. |
| 4 | Close any doors between you and the Bracken. |
| 5 | If it attacks, a teammate can shove it off with a shovel hit. |
Kill Strategy: Brackens have 5 HP. A coordinated team can kill one: one player acts as bait (looking at the Bracken to hold its attention) while another hits it from behind with a shovel. This is risky — one mistimed hit and the bait player dies.
2. Coil-Head
Also known as: The Weeping Angel, Spring-Head
The Coil-Head is a mannequin-like entity with a spring for a neck and a human head mounted on top. It operates on a simple rule: it only moves when you are not looking at it.
| Attribute | Detail |
|---|---|
| Danger Level | 7/10 |
| Spawn Locations | All moons, interior only |
| Detection Method | Proximity, line of sight |
| Speed | Fast (when you look away) |
| HP | Invincible (cannot be killed) |
| Can be Killed? | No |
| Sound Cues | Metallic clicking, spring sounds |
| First Appearance | v35 |
Behavioral Analysis:
- Coil-Heads patrol corridors and rooms at a slow walk when observed.
- The moment no player has direct line-of-sight, the Coil-Head lunges forward rapidly.
- It instantly kills players on contact.
- Multiple Coil-Heads can spawn on harder moons.
- They cannot be killed by any means.
Counter-Strategy:
| Situation | Action |
|---|---|
| Alone, Coil-Head approaches | Back away while maintaining eye contact |
| Multiple players | Take turns looking at it |
| Need to turn a corner | Back around the corner while facing it |
| Coil-Head + other monster | This is a deadly combination. Prioritize escape. |
The “Coil-Head Dance”: When multiple players are present, you can “pass” the Coil-Head by alternating who looks at it. Player A looks while backing up, then Player B catches line-of-sight as Player A rounds a corner. This allows the team to navigate past Coil-Heads safely.
Critical Rule: Never look away from a Coil-Head in a dead-end room. You will die.
3. Thumper (Crawler)
Also known as: The Blind Dog, Crawler
The Thumper is a blind, quadrupedal creature with an elongated body and powerful legs. It cannot see but has excellent hearing. When it detects a player, it lets out a distinctive screech and charges.
| Attribute | Detail |
|---|---|
| Danger Level | 6/10 |
| Spawn Locations | All moons, interior only |
| Detection Method | Sound-based (footsteps, voice, doors) |
| Speed | Fast charge (faster than sprint) |
| HP | 3 hits (shovel) |
| Can be Killed? | Yes, 3 shovel hits or 1 shotgun blast |
| Sound Cues | Loud screech before charging, heavy footsteps |
| First Appearance | v35 |
Behavioral Analysis:
- Thumpers patrol the facility, head low to the ground, listening.
- When they hear a player (footsteps, door opening, voice chat), they screech and charge.
- Their charge is faster than sprint speed — you cannot outrun one in a straight line.
- They can open doors.
- After a failed charge, they pause briefly to reorient.
Counter-Strategy:
| Technique | How To |
|---|---|
| Walking | Walk (shift by default) instead of running to avoid detection |
| Door Stalling | Close doors behind you — Thumpers are slowed by doors |
| Juking | Break line of sight around corners, then crouch and stay still |
| Killing | 3 shovel hits from behind while it is chasing a teammate |
| Stun Grenade | Freezes it for 5 seconds, enough to kill or escape |
Pro Tip: A Thumper’s charge has a brief wind-up. If you hear the screech, immediately break line of sight around a corner or door. It will charge to your last known position, giving you time to reposition.
4. Eyeless Dog
Also known as: Blind Dog, Hellhound
The Eyeless Dog is a large, canine-like creature with a featureless face (no eyes, no apparent nose). It is completely blind but hunts with extreme sensitivity to sound.
| Attribute | Detail |
|---|---|
| Danger Level | 8/10 (outdoor), 6/10 (if careful) |
| Spawn Locations | Outdoor areas on all moons |
| Detection Method | Sound only |
| Speed | Fast sprint |
| HP | 5 hits (shovel) |
| Can be Killed? | Yes, 5 shovel hits or 2 shotgun blasts |
| Sound Cues | Barking, growling, heavy panting |
| First Appearance | v40 |
Behavioral Analysis:
- Eyeless Dogs wander the outdoor map sniffing and listening.
- They cannot see anything — standing still right in front of one is safe as long as you make no sound.
- They react to: footsteps (running especially), voice chat, doors opening, equipment sounds, and scrap dropping.
- Once alerted, they run to the sound source and attack anyone in their path.
- They can be distracted by sound sources (Radar Boosters, Boombox).
Counter-Strategy:
| Situation | Action |
|---|---|
| Near an Eyeless Dog | Stop moving completely. Do not even turn. |
| Need to move | Crouch-walk. Crouching reduces footstep noise. |
| Dog is close | Hold still and do not speak on voice chat. |
| Dog is chasing you | Run to the ship. Jump over obstacles to break its pathing. |
| Multiple dogs | Use a Radar Booster or Boombox to lure them away. |
The “Dog Dance”: Experienced players can walk past Eyeless Dogs by crouch-walking and stopping whenever the dog turns toward them. Each dog has an aggro cone — if the dog’s head points toward you, freeze. When it looks away, move again.
5. Forest Keeper
Also known as: The Giant, Earth Leviathan
Forest Keepers are enormous humanoid giants that patrol the outdoor areas of certain moons. They have a single large eye and wear tattered clothing. They can grab and eat players in two bites.
| Attribute | Detail |
|---|---|
| Danger Level | 8/10 |
| Spawn Locations | Outdoor, Vow and harder moons |
| Detection Method | Line of sight |
| Speed | Slow walk (deceptively fast over distance) |
| HP | 8 hits (shovel) — extremely hard to kill |
| Can be Killed? | Yes but impractical (requires 8 shovel hits or 3 shotgun) |
| Sound Cues | Tremendously loud footsteps, deep growls |
| First Appearance | v35 |
Behavioral Analysis:
- Forest Keepers patrol outdoor areas, scanning for players.
- When they spot a player, they walk toward them and attempt to grab them.
- Being grabbed results in being eaten: first bite deals damage, second bite kills.
- They can be distracted by loud noises and will investigate.
- They cannot enter the ship but can block the doorway.
Counter-Strategy:
| Technique | How To |
|---|---|
| Line-of-Sight | Stay behind trees, rocks, and terrain to break LOS |
| Indoor Escape | Go inside the facility — Forest Keepers cannot enter |
| Ship Dash | Time your sprint to the ship between its patrol paths |
| Boombox Lure | Place a Boombox playing music away from your path |
| Stun Grenade | 5 seconds of stun to run past |
6. Jester
Also known as: Jack-in-the-Box, Music Box Monster
The Jester appears as a small jack-in-the-box toy carried by a faceless figure. It patrols in harmless mode (winding its music box), but once fully wound, it transforms into a fast, lethal killing machine.
| Attribute | Detail |
|---|---|
| Danger Level | 9/10 (wound up), 2/10 (winding) |
| Spawn Locations | Interior, harder moons (Offense+) |
| Detection Method | Patrol path (winding), line of sight (chase) |
| Speed | Slow (winding), Very Fast (chase) |
| HP | Invincible |
| Can be Killed? | No |
| Sound Cues | Music box melody (winding), loud roar (chase) |
| First Appearance | v40 |
Behavioral Analysis - Two Phases:
| Phase | Duration | Behavior |
|---|---|---|
| Winding (Safe) | 30-45 seconds | Patrols facility playing music. When a player is nearby, it stops and cranks its crank. |
| Wound Up (Deadly) | Until it loses tracking | Chases the nearest player at high speed, instantly killing on contact. Cannot be stopped. |
Counter-Strategy:
| Phase | Action |
|---|---|
| Hear the music | Immediately identify where the Jester is. Warn team. |
| It starts cranking | LEAVE THE FACILITY. Go outside. |
| It is chasing | Run for the exit. Close doors behind you. Juke around corners. |
| After chase | The Jester returns to winding mode after ~20 seconds of not finding anyone. |
Critical Rule: When you hear a Jester start cranking, announce it on voice chat immediately. The whole team needs to evacuate. One player ignoring the warning equals one dead player.
7. Snare Flea
Also known as: Ceiling Monster, Head Grabber
The Snare Flea is a small, insect-like creature that clings to ceilings and drops onto players passing below. It latches onto the player’s head, slowly suffocating them while the player struggles.
| Attribute | Detail |
|---|---|
| Danger Level | 5/10 |
| Spawn Locations | Interior, all moons |
| Detection Method | Proximity (drops when player passes under) |
| Speed | Stationary (on ceiling), Slow (on player) |
| HP | 1 hit (shovel) |
| Can be Killed? | Yes, one shovel hit |
| Sound Cues | None while on ceiling. Muffled sounds while on player. |
| First Appearance | v35 |
Behavioral Analysis:
- Snare Fleas are stationary on ceilings until a player walks under them.
- They drop onto the player’s head and cover their face.
- The player’s vision is obscured and they take damage over time until dead.
- A struggling player can shake the Flea off after several seconds, or a teammate can hit it off.
- They are very easy to spot if you look up.
Counter-Strategy:
| Step | Action |
|---|---|
| Prevention | Look at ceilings before entering rooms. Scan with flashlight. |
| If grabbed | Mash E to struggle. Teammate hits you with shovel to remove it. |
| Killing | One shovel hit on the ceiling kills it before it drops. |
8. Hoarding Bug
Also known as: Loot Bug, Item Hoarder
The Hoarding Bug is a beetle-like creature that collects scrap items and brings them to its nest. It is generally passive but becomes aggressive if you take items from its territory or stare at it too long.
| Attribute | Detail |
|---|---|
| Danger Level | 4/10 |
| Spawn Locations | Interior, all moons |
| Detection Method | Visual range |
| Speed | Moderate |
| HP | 2 hits (shovel) |
| Can be Killed? | Yes, 2 shovel hits or 1 shotgun blast |
| Sound Cues | Chittering, skittering legs |
| First Appearance | v35 |
Behavioral Analysis:
- Hoarding Bugs patrol rooms, picking up loose scrap and carrying it back to their nest.
- They are territorial — if you enter their nest room, they raise their arms in warning.
- If you continue approaching or stare at them, they shriek and attack.
- Their attack deals moderate damage but is not an instant kill.
- They steal items from the ground — if you drop something, they may take it.
Counter-Strategy:
| Situation | Action |
|---|---|
| Passing by | Do not make eye contact, move through quickly |
| It is threatening | Back away slowly |
| It attacks | 2 shovel hits kills it easily |
| It took your item | Either kill it or wait for it to drop the item (it will eventually) |
Pro Tip: You can use Hoarding Bugs to your advantage. They collect scrap into neat piles at their nest. Find the nest and you may find more scrap than you expected.
9. Hygrodere
Also known as: The Blob, Slime
Hygrodere is a large, amorphous green slime that slowly oozes through the facility. It deals damage on contact and can block corridors if it spreads.
| Attribute | Detail |
|---|---|
| Danger Level | 3/10 |
| Spawn Locations | Interior, all moons |
| Detection Method | Proximity (it moves randomly) |
| Speed | Very slow |
| HP | Invincible |
| Can be Killed? | No |
| Sound Cues | Wet squelching, bubbling |
| First Appearance | v35 |
Behavioral Analysis:
- Hygrodere oozes through rooms and corridors at walking speed.
- It cannot be damaged or stopped.
- Contact deals steady damage — you have about 5-8 seconds before dying.
- It can split into smaller blobs.
- It follows players very slowly (it can sense heat?).
Counter-Strategy:
| Situation | Action |
|---|---|
| See the blob | Go around. It is slow. You have plenty of time. |
| Blocking a path | Wait for it to move, or find another route. |
| Cornered by it | Run through it. The damage is survivable. |
| Split blobs | Same strategy — slow and easy to avoid. |
10. Spore Lizard
Also known as: The Friendly Lizard, Spore Guy
The Spore Lizard is a small, harmless lizard with glowing spots on its back. When threatened, it releases a cloud of spores that blur vision temporarily. It is completely non-lethal.
| Attribute | Detail |
|---|---|
| Danger Level | 1/10 |
| Spawn Locations | Interior, all moons |
| Detection Method | Random patrol |
| Speed | Medium (will run from players) |
| HP | Cannot be killed |
| Can be Killed? | No (it is harmless, do not try) |
| Sound Cues | Soft chirping |
| First Appearance | v35 |
Behavioral Analysis:
- Spore Lizards wander the facility, completely ignoring players.
- If approached, they release a cloud of pink/blue spores that blur vision for 5-10 seconds.
- After releasing spores, they scuttle away to a different area.
- They do not deal damage, do not attack, and cannot kill.
Counter-Strategy:
| Situation | Action |
|---|---|
| See the lizard | Ignore it. It is harmless. |
| It spored you | Wait a few seconds for vision to clear. |
| Worried players | Tell your team it is just a Spore Lizard — no threat. |
Common Mistake: New players often panic when a Spore Lizard releases spores, thinking they are being attacked. It is completely harmless. Do not waste a stun grenade on it.
11. Ghost Girl
Also known as: The Spectre, Haunting Ghost
The Ghost Girl appears as a small figure in red clothing. She haunts a single player, appearing only to them. As the haunting progresses, she appears closer and closer until she kills the player.
| Attribute | Detail |
|---|---|
| Danger Level | 8/10 |
| Spawn Locations | Interior, harder moons (March+) |
| Detection Method | Target selection (random) |
| Speed | Variable (teleports) |
| HP | Invincible |
| Can be Killed? | No |
| Sound Cues | Static on affected player’s walkie, footsteps |
| First Appearance | v45 |
Behavioral Analysis - Four Stages:
| Stage | Visual | Action Needed |
|---|---|---|
| Distant | See her far away, briefly | She has chosen a target |
| Approaching | Appears closer, more frequently | Warn team, identified target |
| Close | Right next to the player | Target should leave the facility |
| Kill | Touches the player | Instant death for target |
Counter-Strategy:
| Technique | How To |
|---|---|
| Identify target | Only the affected player can see her. Ask “can anyone see a little girl?” |
| Evacuate target | The haunted player should leave the facility and stay near the ship |
| Delay | Staying near other players may delay the kill (unconfirmed) |
| No known cure | She cannot be stopped, only delayed |
Note: The Ghost Girl is one of the least understood entities. There is no confirmed way to prevent her kill. The best strategy is to have the haunted player wait outside the facility so they do not die mid-loot-run.
12. Nutcracker
Also known as: The Shotgun Soldier, Nutcracker Guard
The Nutcracker is a large, wooden soldier that patrols mansion/laboratory interiors carrying a shotgun. It periodically stops, scans its surroundings, and fires at any player it sees.
| Attribute | Detail |
|---|---|
| Danger Level | 7/10 |
| Spawn Locations | Mansion/Lab interiors, Offense+ |
| Detection Method | Patrol path + visual scan |
| Speed | Moderate walk |
| HP | 4 hits (shovel) |
| Can be Killed? | Yes, drops shotgun and shells |
| Sound Cues | Heavy wooden footsteps, mechanical clicking |
| First Appearance | v50 |
Behavioral Analysis:
- Nutcrackers patrol hallways in a set path.
- Periodically, they stop and do a 360-degree scan.
- If they spot a player during a scan, they fire their shotgun.
- The shotgun deals massive damage (2 hits kills).
- After firing, they reload (3 seconds) before scanning again.
- They can be killed, and doing so rewards you with a shotgun and 2-3 shells.
Counter-Strategy:
| Technique | How To |
|---|---|
| Avoid scans | Hide behind walls or furniture when it starts scanning |
| Kill timing | Hit it during its reload animation |
| Team kill | One player baits the shot, another attacks from behind |
| Stun grenade | Stuns through all phases, easy kill setup |
Nutcracker Farming: Killing Nutcrackers is one of the best ways to get shotguns, which are both a powerful weapon and valuable scrap (shotguns sell for 90-150 credits, shells for 10-30 each). For a complete database of all scrap items and value ranges, see our Scrap and Loot Guide.
13. Eyeless Dog (Pack Variant)
On harder moons (Rend, Dine, Titan), Eyeless Dogs can spawn in packs of 2-4. Pack behavior is more aggressive and coordinated.
| Attribute | Value |
|---|---|
| Pack Size | 2-4 dogs |
| Spawn Rate | 30% on Titan, 15% on Rend/Dine |
| Behavior | Spread out to cover more area |
| Counter | Boombox lures work best for multiple dogs |
14. Jester (Rapid-Wind Variant)
On Titan specifically, the Jester can have a shortened wind-up time, reducing the safe period from 30-45 seconds to as little as 15 seconds.

Conclusion
Knowing your monsters is the difference between a successful run and a squad wipe in Lethal Company. Each entity has a specific behavioral pattern and a counter-strategy. The most dangerous situations arise when multiple monster types appear together — a Coil-Head blocking a corridor while a Bracken stalks you from behind, or a Jester winding up while Eyeless Dogs patrol outside.
Master the monsters one at a time. Learn the Bracken dance before you tackle Titan. Practice the Coil-Head stare on Assurance. Use the terminal bestiary command to review scanned entities in-game, and always, always check the ceiling. For a full list of terminal commands, see our Terminal Commands Guide.
