Spasming arms or head, a stretched neck, and a hunched back. Sometimes the twitching is only visible when you check the camera feed rather than looking at the patient directly.
Animal Hospital Twitching is one of the 19 anomalies in the Roblox game, and it is caught with nothing but your own eyes at the check-in window.

| How to confirm | The twitch can be camera-exclusive — check CCTV before you commit to treating. |
| If you let it in | Twitching always becomes a Mimic in recovery — same rule as Staring. Watch the room for a bit after treatment instead of immediately moving to the next patient. |
Because the twitch can be camera-exclusive, don't rule this one out just because the patient looks still in person — if something about the posture (stretched neck, hunch) feels off, check CCTV before you commit to treating them.
Twitching is on the cheapest channel there is — you catch it by looking at the patient, with no tool and no walk to the monitors. That is true of only 8 of the 19 anomalies in the game, so treat the free ones as the exception rather than the rule.
| Check | Catches | What skipping it costs you |
|---|---|---|
| Naked eye ← this one | 8 of 19 | 8 anomalies you will never see |
| CCTV | 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.
Twitching always becomes a Mimic in recovery — same rule as Staring. Watch the room for a bit after treatment instead of immediately moving to the next patient.
Refusing Twitching at the window costs you nothing. Letting it through hands you the 🎭 Mimic instead — so the numbers below are what the identification check is actually worth.
| Where it turns up | Disguised as a patient. It can reveal itself at check-in, mid-treatment, or during recovery — often right after muttering "I'm hungry...". Can appear in Rooms 1–8 or at the front desk. |
|---|---|
| What it costs you | −15 sanity on the initial attack, then −6 sanity per 0.5 seconds while it's actively attacking you. If it kills a patient, that counts against you as an animal death. |
| How you deal with it | A single gun round, or a taser, puts it down. Bare-handed fighting also works but drains sanity fast — faster in a group. A Bed Monster can also kill it. It's slower than you, so kite it toward the front desk taser if you're caught without a weapon. |
| What you need in hand | Gun or Taser |
As a drain it runs at 12 sanity a second, so a full 61-sanity bar lasts about 5 seconds of continuous exposure. That is measured against the 61 sanity you start a shift with if you have not bought a class.
Same trap as the staring pair: one is caught by looking at the patient, the other only through the CCTV feed. They are not the same entry.

|---|---|---|
| 👁️ Twitching ← this page | In person | Spasming arms or head, a stretched neck, and a hunched back. Sometimes the twitching is only visible when you check the camera feed rather than looking at the patient directly. |
| 📹 Camera Twitching | On CCTV | Twitches only when viewed through the camera feed — in person, the same patient looks completely normal. |
You are at the check-in window with the patient in front of you, which shapes the answer: the shutter is already within reach, so refusing is the cheapest move available — it costs no sanity and no ammunition.
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 your own eyes, 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 |
|---|---|
| 👁️ Realistic Face | Big eyes with dark pupils, heavy under-eye bags, and a grin that looks painted on rather than expressed. It speaks in a low, distorted voice — noticeably off from a normal patient's tone. |
| 👁️ Three Eyes | Three misplaced, glowing red eyes replace the normal pair. Look closely and you can sometimes still make out the original two eyes underneath the extra set. |
| 👁️ Crooked Face | A warped, tilted grin with sharp teeth, paired with mismatched eyes that sit visibly too high on the face — the proportions are just wrong in a way a normal patient's face never is. |
| 👁️ X-rayed Face | Small, wide, round eyes with black pupils, combined with teeth that look unsettlingly real — almost too anatomically correct compared to the game's normal patient models. |
| 👁️ Staring | Its head tracks you — or a random target in the room — constantly. In person the tracking is limited to roughly 60°, but on CCTV there's no limit at all, so the head can swivel further than a real neck should allow. |
| 👁️ Hollow Face | Deep, pitch-black hollow eyes with no visible pupils, constant twitching, and a hunched, slouched posture. |
| 👁️ Tiny Anomaly | The patient is extremely small — far below any normal patient model — and speaks with a very high-pitched voice. Its only documented look so far is a pink bunny with a short tail and three glowing red eyes. |

View All Anomalies →Spasming arms or head, a stretched neck, and a hunched back. Sometimes the twitching is only visible when you check the camera feed rather than looking at the patient directly. The primary way to catch it is checking the patient in person.
Yes — this is one of the 8 anomalies you can catch just by looking at the patient at the window, no equipment needed.
The Mimic. A single gun round, or a taser, puts it down. Bare-handed fighting also works but drains sanity fast — faster in a group. A Bed Monster can also kill it. It's slower than you, so kite it toward the front desk taser if you're caught without a weapon. For scale, it costs −6 every 0.5s while it is attacking.
Twitching always becomes a Mimic in recovery — same rule as Staring. Watch the room for a bit after treatment instead of immediately moving to the next patient.
