All Anomalies in Animal Hospital

Anomalies are disguised monsters mixed in with regular animal patients. They can be identified by appearance, photo anomalies, CCTV footage, or by encountering monsters roaming the hospital. There are three main identification methods: Appearance (visual inspection), Photo (check polaroid), and CCTV (check surveillance cameras).

Detection Methods

There are three main ways to identify anomalies disguised as patients:

  1. Appearance — Look directly at the patient at the reception desk
  2. Photo — Take a polaroid and wait for it to develop on the desk
  3. CCTV — Check surveillance cameras, especially the waiting room camera

Visible by looking directly at the patient at the reception desk. No need to check camera or photo.

Monsters and Hazards

Hazards and threats that roam the hospital corridors and patient rooms.

MonsterDangerHow to Handle
Bed Monster / Monster Under The BedHighAvoid the red line, hop over the bed. Treat the patient and the monster will leave. Loves Maple Syrup - give it some to make it leave safely.
Head Banger / Head KnockerLowClose the shutter while it's rearing back to headbutt. Can't use shutters normally until the monster disappears. Inconvenient but not lethal.
Skinwalker (Hospital Roaming)Very HighUse a gun or taser to shoot the monster. You can also hold E to forcefully dislodge them from their victim, or spam E to punch them if they attack you. Beat the timer before they eat you or a patient.
The StalkerMediumAvoid eye contact if possible. If you do look, you lose 10 Sanity. Not a massive deal but adds up.
TendrilMediumComplete the patient's surgery before the timer runs out. When the mini-game is complete, the tendrils vanish. If you don't make it in time, the patient dies.
Camera Anomaly / Demon Cat JumpscareMediumIGN: Press the Exit button along the bottom of the screen in time, then fix the camera. Eurogamer: Can't avoid outside of not using cams. Jumpscare costs 20 Sanity.
Don't Look Up / Flesh CeilingMediumDon't look up! Looking causes steady sanity damage. To remove: hold Eye Drops, open the door facing inside, jump on the door, slowly look toward the monster until 'Accept Treatment' text appears.
Hiders / Translucent ManHighIGN: Listen for raspy breaths, scan the room, see their eyes and smile. Avoid or use gun/taser. Eurogamer: Run away to the lobby and the translucent man disappears in a puff of smoke.
Death RitualHighBeat the timer and get to their room, then remove all the candles. Removing each candle depletes your own Sanity, but failure means the patient dies.
SlimeLowInteract with each glob of slime to clean it up.
FireMediumGrab the fire extinguisher (right of doors to the shop) and extinguish the fire.

Anomaly Screening Checklist

Before admitting any patient, follow this checklist:

  • Look at the patient directly for 4-5 seconds
  • Take a photo and wait for it to develop on the desk
  • Check the waiting room CCTV camera
  • Compare the photo to the patient appearance
  • If ANYTHING seems off, close the shutters immediately

Pro Tips

  • The waiting room CCTV is the most important camera — check it for every patient
  • Cursed photos drain 10 Sanity if picked up — close the shutter first
  • Some anomalies only appear on one detection method — always use all three
  • Audio cues (Skinwalker roars, Hider breathing) can alert you to danger
  • Keep cameras in good repair — broken cameras leave you blind
