You got hired to work the night shift at an animal hospital. Cartoon animal patients arrive in the waiting room and it is your job — as the antlered doctor with the stethoscope and scalpel — to treat them. The catch: some patients are not what they seem. They are anomalies, corrupted versions of the normal animals, and treating one like a regular patient is a mistake.

It is a survival/anomaly-horror game where you work the night shift as a doctor at an animal hospital. You treat cartoon animal patients, but some patients are anomalies that behave abnormally and must be identified instead of treated. The game mixes cozy clinic roleplay with tension from spotting impostors among your patients. Beginner guide →
Use the 4-layer detection system: Visual (does the patient look normal?), Photo (does the clipboard photo match?), CCTV (does the camera feed look normal?), and Document (does the patient file match?). A fail on any single layer means reject. Only treat when ALL layers pass. Common tell signs include mismatched faces, all-black bodies, three eyes, sharp teeth, and patients standing where they should be seated. Use the anomaly checklist →
Treating an anomaly instead of rejecting it drains your sanity and can cause the anomaly to escalate into a Skinwalker — one of the deadliest threats in the game. Repeated mistakes compound: low sanity impairs your vision and judgment, making further mistakes more likely. How to identify anomalies →
As of the latest check there are no active redeemable codes from the developer Animal Anomaly. The game launched in May 2026 and has not yet added a code redemption system. Our codes page is updated as soon as codes are released. Codes page →
Start as the free Intern class, learn the normal patient roster first (so corrupted versions stand out), buy Coffee as your first shop item for sanity management, and run the full 4-layer check on every single patient before treating. Never rush — speed is what causes misreads. Full beginner guide →
