Surviving the night shift in Animal Hospital comes down to one number on your screen: Sanity. Most monsters in the game do not kill you outright. They drain Sanity over time, and when that bar hits zero, your run ends. Each threat has one correct response, and using the wrong response usually makes things worse or kills a patient. Below is the exact counter for every monster and environmental hazard you will face.
Quick answer: Skinwalkers are the only enemy you can defeat with a weapon. Every other monster is handled by a specific item or action: maple syrup for the Bed Monster, coffee or food for Wall Bangers, looking away from Don’t Look Up and the Stalker, finishing the surgery mini-game for Surgery Tentacles, and running away to de-spawn the Wall Anomaly.
Every monster and the exact counter
Monsters and environmental hazards are separate from patient anomalies. You cannot reject them at the front desk. They appear inside medical rooms, hallways, and corners during your shift, and each one has a single deterministic counter. Memorize this table first, then read the detail below for the threats that have a trap built into them.
| Monster / Hazard | Correct response |
|---|---|
| Skinwalker | Defeat with a weapon (taser/gun) or hold E from behind it; spam E if it is on you |
| Bed Monster | Approach with Maple Syrup equipped to make it vanish; without syrup it grabs you |
| Wall Banger | Approach with coffee or food and interact to remove it |
| Don’t Look Up | Keep your camera down and finish your task; it leaves on its own |
| Stalker | Never look directly at it as you pass; spot it from a distance first |
| Wall Anomaly | Aggro it, then run away; it de-spawns after a while |
| Surgery Tentacles | Finish the surgery mini-game; never shoot or taze it |
| Green Sludge / Slime | Hold E to clear the terrain hazard |
Skinwalkers: the only enemy you fight
A Skinwalker is what an anomaly patient turns into after you accidentally admit it. They can awaken at any random moment, from the second you check them in to when they are sitting in a medical room. Once active, they hunt down patients or you.
Skinwalkers are the single exception to the no-weapons rule. Approach with a taser or gun and defeat it with M1 attacks. If you have no weapon and it is attacking a patient, hold E from behind to take it down cleanly. If it is on you directly, press E multiple times to break free, though you will lose Sanity in the process.
Tip: The cleanest fix is to never let one spawn. Catch anomalies at the desk using visual, camera, and photo signs and hit the shutter button before they walk in. If one does slip through, treating it in a medical room and administering the wrong item also kills it with no point penalty.
Bed Monster: bring Maple Syrup
The Bed Monster spawns beneath the beds in medical rooms and can attack a patient while they are lying down, walking in, or walking out. It also attacks you and any anomalies that get too close.
Equip Maple Syrup and walk up to it. The monster takes the syrup and disappears without harming anyone. Approach it without syrup, and it grabs you, draining Sanity. If it is already dragging a patient under the bed, get close and interact with the patient to help them break free. You have 30 seconds before the monster eats them.
Wall Bangers: clear them with coffee
Wall Bangers appear at random and bang their heads against the glass of your check-in room. The real problem is that they block you from rejecting anomaly patients, which can quickly let a Skinwalker through.
Approach with coffee or other food and interact to remove the Wall Banger calmly. You can also hold E to ask it to leave with no item, but doing so costs a large amount of Sanity. Keep a coffee handy so you never have to take that hit.
Don’t Look Up and the Stalker: keep your eyes away
Two monsters punish you for looking at them. Both deal steady Sanity damage the entire time they are in your view, so the counter is simply where you point your camera.
Don’t Look Up is a fleshy mass of skin and eyeballs that weeps on the ceilings of medical rooms. Keep your camera level, finish whatever task you are doing, and it eventually disappears on its own. Look up at it, and the Sanity drain begins immediately.
The Stalker spawns randomly around corners. Watch for it from a distance, then keep your gaze off it as you walk past. Staring directly at it as you pass costs Sanity.
Wall Anomaly: aggro and run
The Wall Anomaly spawns on walls and chases you when you are nearby, hitting you for Sanity or stealing items. There is no weapon counter. Pull its attention, then run away and keep your distance. It de-spawns after a short while on its own.
Surgery Tentacles and the Purple Monster: never attack them
Surgery Tentacles spawn in Room 8 while you operate. The instinct to shoot or taze them is exactly wrong. The tentacle (also seen as the purple monster during the surgery emergency) is connected directly to your patient, so any attack on it kills the patient instantly.
The only safe move is to ignore the monster and finish the surgery mini-game. Follow the steps shown on the blackboard behind the bed and administer items in the right order. During the purple monster emergency, you have 45 seconds to complete the surgery. Once the mini-game is done, the monster disappears, and you continue treatment normally.
Green Sludge and Slime: a hold-E cleanup
Green Sludge is a terrain hazard rather than an active hunter. Walk up to it and hold E to clear it out of your path. It does not chase you, but leaving it in place gets in the way as you move between rooms.
Two rules that keep your Sanity alive
First, remember that weapons only work on Skinwalkers. For every other monster, reaching for a taser or gun either does nothing or kills your patient. Match the threat to its item or action instead.
Second, stock the three items that solve the most threats before they appear. Carry Maple Syrup for Bed Monsters, coffee or food for Wall Bangers, and a charged taser for any Skinwalker that slips past the desk. With those ready and a habit of keeping your camera level, most of a shift’s monsters are handled before they cost you a single point of Sanity. Keep an eye on your Sanity bar throughout, and top it up with coffee and food from the shop between threats so a long shift never drains you to zero.
