Animal Hospital is the latest horror game taking Roblox by storm, and it does not ease you in gently. You play the role of a doctor running a shift, treating patients while identifying and rejecting the monsters hiding among them. Fail to spot an anomaly, let it inside, and you will watch it tear through your patients and drain your sanity meter fast.
The tricky part is that anomalies do not always announce themselves. Some show up with three glowing red eyes and make your job easy. Others look completely normal at the window but reveal themselves only through a photograph or the security cameras. Then there are the hazards that stalk the halls regardless of whether you correctly close the shutters. This guide covers every anomaly in Animal Hospital, how to identify each one, and exactly what you need to do to survive.
How Anomalies Work in Animal Hospital
Each shift in Animal Hospital sends a set number of patients to your check-in window. A random number of these patients are anomalies disguised as regular visitors. You need to identify the imposters and reject them by closing the shutter before they enter a treatment room.
Anomalies fall into three identification categories: appearance, photo, and security camera. Some reveal themselves immediately at the window. Others require you to take their photograph and inspect it carefully. A third group looks completely normal until you check the CCTV footage. A single patient can show multiple anomaly types at once, so always check all three methods before letting anyone through.
If an anomaly enters a treatment room, it can transform into a Skinwalker and attack your patients. Letting one through also drains your sanity, which is already under constant pressure from the hazard creatures roaming the hospital.
Security cameras become available only after Dr. Harlow arrives to repair them, which happens after you treat two to three patients. Until then, you rely solely on appearance checks and photographs.
All Appearance Anomalies in Animal Hospital
Appearance anomalies are visible at the check-in window without any equipment. Spot any of the following and close the shutter immediately. No need to check the photo or cameras first.
| Anomaly | What It Looks Like | How to Spot It |
|---|---|---|
| Three Eyes | A patient with three glowing red eyes | Immediately obvious; voice sounds low-pitched and distorted |
| Hollow Face | Dark hollow eye sockets and a blank, open-mouthed expression | Patient twitches constantly; guaranteed to trigger a death ritual if allowed in |
| Mismatched Eyes and Sharp Teeth | Two uneven glowing eyes and a crooked smile with sharp teeth | Low, distorted voice; nothing about this one blends in |
| Unnatural Facial Appearance (Variant 1) | Large eyes with heavy eyebags and an oversized drawn-on smile | Stares at you as you move; low distorted voice |
| Unnatural Facial Appearance (Variant 2) | Small, wide eyes with a set of realistic human teeth | Same staring behavior and distorted voice as Variant 1 |
| Twitching | Looks normal at first glance | Arms jerk suddenly, head snaps back, neck stretches at unnatural angles; watch for at least 4-5 seconds |
| Hunched Posture | Patient stands with a visible hunch | Almost always paired with twitching; no normal patient ever hunches |
All Photo Anomalies in Animal Hospital
Photo anomalies look completely normal at the window. You need to take their photograph using the desk camera and examine the result carefully. Before picking up any photo, wait for it to finish processing on the desk. If anything looks off while it is still developing, close the shutter without touching it. Picking up a cursed photo mid-process costs you 10 sanity points.
| Anomaly | What to Look For | Action |
|---|---|---|
| Different Eyes | Photo shows different eye shape, eyelids, or pupils compared to the patient at the window | Close shutter |
| Different Ears | Photo shows different ear shape, ear color, or missing/extra horns | Close shutter |
| Incorrect Photo | Photo shows a completely different character model, different markings, or a different animal entirely | Close shutter |
| Static Photo | Grainy, staticky film covers the photograph | As of June 2026, static alone is not always conclusive; shoot with a gun to test; if patient faints, they are normal |
| Unprocessed Photo | Photo fails to render and cannot be inspected | Treat as anomaly if the next patient’s photo renders fine |
| Cursed Photo | Photo shows bloodshot eyes, a grotesque smile, or blurred features | Do not pick up while processing; close shutter immediately |
All Security Camera Anomalies in Animal Hospital
Security camera anomalies pass both the window check and the photo check without triggering anything. CCTV is the only way to catch them. Always run a quick camera sweep on patients who clear the first two tests.
The waiting room camera is your most valuable tool. It shows the patient’s full body, ears, tail, and face. If any camera breaks mid-shift, fix the waiting room camera before any other.
| Anomaly | What to Look For on Camera |
|---|---|
| Black Eyes | A black bar covers the patient’s face with a pair of realistic eyes drawn on top |
| Unnatural Body | Patient appears heavily stretched and distorted; body shape changes every time you switch camera angle |
| Staring at the Camera | Patient stares directly into the camera at all times, even while walking |
| Void / Black Patient | Patient appears entirely black with no visible features; a rarer disfigured version also exists |
| Camera Twitching | Patient twitches only in CCTV footage; completely still at the window and in photos; watch for 4-5 seconds |
| Disguised Shapeshifter | Patient shows a wide-open mouth with sharp teeth and a long tongue; use the lobby camera for a side-on view to confirm |
| Mismatching Ears | Patient’s ears or horns on CCTV differ from what you see at the window; use the waiting room camera for the clearest view |
All Hazard Anomalies in Animal Hospital
Hazard anomalies are threats you cannot close the shutter on. They appear inside the hospital during your shift and force specific responses to deal with them.
| Anomaly | Where It Appears | How to Identify | How to Deal With It |
|---|---|---|---|
| Flesh Ceiling | Patient room ceiling | Groaning sounds, dripping saliva, screen flashes “don’t look up” | Avoid looking up; treat the patient and the creature leaves when the patient does |
| Translucent Man | Patient room wall | A faint outline and pair of eyes visible against the wall tiles; staring at it triggers a chase | Run to the lobby and it vanishes |
| Skinwalker | Hospital hallways | Heavy breathing; an exact copy of a patient you have already treated; emergency alert fires if it attacks | Taser to take it down fast; hold E to pry off a victim; spam E to fight back if it attacks you |
| Monster Under the Bed | Underneath patient beds | Red box on the floor, large black hands, red eyes under the mattress | Stay outside the red box; hop over the bed to treat the patient; bring Maple Syrup to neutralize it |
| The Stalker | Hospital hallways and corners | A towering shadow shaped like a bunny peering around corners | Avoid eye contact; each look costs 10 sanity but it does not actively attack |
| Demon Cat | CCTV hallway cameras | Demonic cat with glowing red eyes standing at the end of a hallway; camera zooms in automatically | No avoidance once triggered; costs 20 sanity; avoid the cameras if you want to skip the risk |
| Death Ritual | Patient treatment room | Patient floating above the bed, candles lit, red light, all nearby equipment glitched; emergency alert fires | Sprint to the room before the timer expires and remove all candles; each candle costs sanity |
| The Head Banger | Right-side reception window | A hollow-faced patient banging their head against the glass | Close the shutter while it pulls back to headbutt; it cracks the glass and leaves |
| Tendril Surgery | Room 8 operating table | Purple tentacles emerging from the patient’s abdomen; emergency notification fires immediately | Complete the surgery mini-game before the timer runs out; do not taser or give coffee or the patient dies instantly |
| Slime | Hospital floor | A patient leaking bright green slime as they walk | Interact with each puddle to clean it up |
| Fire | Empty patient rooms | Room engulfed in flames | Grab the fire extinguisher to the right of the shop doors and extinguish the fire |
| Hiders | Walls, curtains, and windows | Camouflaged monsters with visible eyes and a smile; loud raspy breathing gives their location away | Use gun, taser, or fire extinguisher; they appear in groups of 5-6 so clear the whole group at once |
How to Identify and Remove Anomalies in Animal Hospital
The core mechanic for handling patient anomalies is the shutter. Press the red button behind the security camera at the check-in window to close the shutter and refuse entry to a suspicious patient. Anomalies blocked by the shutter will leave the building.
You cannot access the shutters at the very start of a shift. Dr. Harlow arrives to repair them after you treat your first two to three patients. During those early rounds, pay maximum attention to appearance checks since the photo and camera are your only other tools.
If an anomaly slips through, retrieve the taser or gun from your office and neutralize the creature before it can attack a patient or fully transform. Treating an anomaly with the wrong treatment also kills it, though doing so reduces your shift summary rewards.
Check all three identification methods on every patient before clearing them: appearance at the window, the photograph, and security camera footage. Staying methodical is what keeps your sanity meter and your patients intact. Play Now!
