Anomalies

The Three Detection Layers

Every anomaly in Animal Hospital is caught by one of three checks at the admission window: a direct visual review at the live monitor, a Photo Camera snapshot, or the security-camera feed. Some anomalies are detectable by two layers, most by only one. Skip a layer for any patient and you're betting that the anomaly (if there is one) happens to belong to a class you can still catch.

The catalogue below is organised by detection layer so you can drill into the specific check you missed.

The Six in 60 Seconds

If the queue is moving fast and you only have a moment to scan, these six visual-class anomalies are the ones you can rule out at the window with your eyes alone — no tools needed: Three Eyes, Hollow Face, Wide Eyes and Creepy Smile, Mismatched Eyes and Sharp Teeth, Human Teeth, Twitching. The first five are obvious if you actually look at the face for a beat; Twitching needs you to hold the view for four or five seconds because the cue is movement, not anatomy.

Why Every Missed Anomaly Becomes a Skinwalker

A common misconception is that different anomalies turn into different floor enemies once admitted. They don't. Per the Destructoid walkthrough, every admitted anomaly transforms into a Skinwalker (see /wiki/enemies/skinwalker). The visual / photo / CCTV cue tells you how you should have caught it; the consequence is uniform — a hostile is now loose in the hospital, and you're in combat instead of intake.

This is why the detection workflow matters more than knowing which anomaly is which.

When Paperwork Beats Photos

Two anomalies in our catalogue — Missing Appointment and Mimic Patient — defeat the visual / photo / CCTV layers entirely. Missing Appointment requires you to check the appointment list against the queued patient; Mimic Patient requires you to remember what recurring patients (Ratthew is the canonical mimicked NPC) normally look like in Shift 1-3 so you can spot a copy in later shifts. These aren't easier than visual anomalies — they're a different kind of effort.

Patches Add New Ones — Here's How to Spot Them

When a patch lands, peer wikis usually publish updated entries within a week. The reliable signal that a new anomaly exists: you see a tell in-game that doesn't match any catalogued entry. When that happens, flag it via the Sources page and we'll add it. Counts across community wikis hover around 17-19 right now — if you've personally observed a tell that doesn't match any entry here, the catalogue is missing one.

FAQ

Are anomalies the same as enemies? No. Anomalies are pre-admission tells you act on at the window. Enemies are post-admission threats. Skinwalker exists on both sides because the admit-phase tells and the floor-combat encounter share the entity.

Why are there different anomaly counts across guides? Most authoritative sources list 17 (visual 6 + CCTV 5 + photo 6). Paperwork-class anomalies like Missing Appointment and Mimic Patient are sometimes documented as a separate category that pushes the count higher.

Do I need the Photo Camera for every patient? Strictly: only for photo-class anomalies. Practically: yes. The photo step is the only way to catch any of the six photo-class tells.

Can I tell what anomaly type a Skinwalker came from? No — once admitted, all anomalies converge to the same Skinwalker form. The detection-side classification doesn't carry into combat.

Does the appointment list always show the queued patient? Real patients appear on the list. Missing Appointment anomalies do not — that's the entire mechanic.

Where do I practice the detection workflow? Shifts 1-3 are tutorial-paced with generous tells. Run those repeatedly before chasing harder shifts; the muscle memory pays off most from Shift 4 onward.
