Appears entirely pitch black on the camera feed — no visible features at all, just a silhouette of solid black.
Animal Hospital Void Black is one of the 19 anomalies in the Roblox game, and it is caught only on the CCTV feed, never by looking at the patient.

This is the simplest camera tell to spot: there's no ambiguity between a shadow and a fully black silhouette on a well-lit feed. If a patient reads as a black shape with no detail on CCTV, that's the whole check.
Void / Black does not show up when you look at the patient. It is visible only through the CCTV monitor station — and it is one of 8 of the 19 anomalies that behave that way. Skipping that check to save a walk to the monitors and time off the floor is not saving you time; it is agreeing to miss 8 of the things you are being paid to catch.
| Check | Catches | What skipping it costs you |
|---|---|---|
| Naked eye | 8 of 19 | 8 anomalies you will never see |
| CCTV ← this one | 8 of 19 | 8 anomalies you will never see |
| Polaroid | 3 of 19 | 3 anomalies you will never see |
One patient can carry more than one of these at once, so a clean naked-eye read is not a clean bill of health.
The specific recovery outcome for this anomaly hasn't been documented by the community yet — we only publish what's confirmed. What is confirmed: letting an anomaly in usually triggers a Death Ritual, spawns a monster, or turns the patient into a Mimic. A wrong treatment kills an anomaly with no penalty to you (it just lowers your end-of-shift reward), and tasing or shooting a confirmed anomaly nets +2 sanity. Tasing or shooting a normal animal by mistake costs −15 sanity — when in doubt, shutting the window is always the safe move.
You are at the monitor station, away from the door, which shapes the answer: this is the awkward case, because you still have to get back to the window before the patient is admitted — identify it and move, rather than watching it longer than you need to.
Refuse it. Shutting the window costs nothing and ends the problem. It does not hurt your shift score, and it is always available.
Or put it down. A confirmed anomaly can be tased or shot, and doing so is worth +2 sanity. A wrong treatment also kills one with no sanity penalty — it only lowers the end-of-shift reward.
What it costs to guess. Tasing or shooting a normal animal by mistake is −15 sanity, nearly a quarter of the 61 you start with. That gap is the whole reason to confirm before acting rather than acting on a hunch.
An anomaly cannot be knocked out the way a normal patient can, so "it fainted, it must be fine" is not a test. Neither is slime on the floor — patients drip it too.
Once you are already looking through the CCTV monitor station, these cost you nothing extra to rule out. Knowing them as a set is what turns the check from a habit into a decision.
| Anomaly | What gives it away |
|---|---|
| 📹 Black Eyes | On the security camera feed, its face is covered by a black bar with a pair of unnervingly realistic eyes staring back through it. |
| 📹 Unnatural Body | A severely stretched, warped body that only shows up on the camera feed. The shape actually changes each time you toggle the feed on and off, and even the printed photo distorts while the camera is open. |
| 📹 Staring at Cameras | Looks directly into the CCTV lens at all times — even while walking around, which a normal patient never does. |
| 📹 Camera Twitching | Twitches only when viewed through the camera feed — in person, the same patient looks completely normal. |
| 📹 Disguised Mimic | Shows its true Mimic form only on the camera feed. In person it looks completely normal all the way up until it reaches check-in. |
| 📹 Mismatching Ears | Ears or horns visible on the camera feed don't match what you see on the patient at the window. |
| 📹 Mismatching Eyes | Eye shape or color on the camera feed doesn't match the patient standing in front of you. |

No. It only shows up through the CCTV monitor station. It is one of 8 anomalies out of 19 that are invisible without it, which is the whole argument for not skipping that check.
The specific recovery outcome for this anomaly isn't documented by the community yet. Treat any confirmed anomaly the same way regardless: a wrong treatment kills them with no penalty to you but lowers your end-of-shift reward, and tasing or shooting a confirmed anomaly gives +2 sanity. When in doubt, shutting the window is always safe.
