The patient is extremely small โ far below any normal patient model โ 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.
Animal Hospital Tiny Anomaly 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.

What you'll see
Extremely small patient โ far below the normal model size
Very high-pitched voice
Only documented look: a pink bunny with a short tail and three glowing red eyes
How to confirm
Often stacks with Static Photo and Unnatural Body โ a photo or CCTV check usually double-confirms what the size already told you.
If you let it in
It stays calm at the window, then turns hostile once checked in. It can also arrive during the Ambulance Event mixed in with genuine victims โ size-check ambulance patients too.
How to spot the Animal Hospital Tiny Anomaly anomaly
Added in the July 25 Hazmat update, this is the newest entry on the list. Size alone is the check: no normal patient spawns anywhere near this small. It also tends to stack other tells on top โ a static photo and a warped body on CCTV are its most common companions โ so a second-channel check usually confirms what your eyes already told you.
Why this one needs your own eyes
Tiny Anomaly is on the cheapest channel there is โ 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.

One patient can carry more than one of these at once, so a clean naked-eye read is not a clean bill of health.
What happens if you let Tiny Anomaly into the hospital

You have spotted it โ now what
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 โ it costs no sanity and no ammunition.
1
Refuse it. Shutting the window costs nothing and ends the problem. It does not hurt your shift score, and it is always available.
2
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 โ it only lowers the end-of-shift reward.
3
What it costs to guess. Tasing or shooting a normal animal by mistake is โ15 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 โ patients drip it too.
The other 7 you are checking for at the same time
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.
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 โ noticeably off from a normal patient's tone.
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.
A warped, tilted grin with sharp teeth, paired with mismatched eyes that sit visibly too high on the face โ the proportions are just wrong in a way a normal patient's face never is.
Small, wide, round eyes with black pupils, combined with teeth that look unsettlingly real โ almost too anatomically correct compared to the game's normal patient models.
Its head tracks you โ or a random target in the room โ constantly. In person the tracking is limited to roughly 60ยฐ, but on CCTV there's no limit at all, so the head can swivel further than a real neck should allow.
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 patient is extremely small โ far below any normal patient model โ 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. The primary way to catch it is checking the patient in person.
Can you see the Tiny Anomaly anomaly with the naked eye?
Yes โ this is one of the 8 anomalies you can catch just by looking at the patient at the window, no equipment needed.
What happens if I let a Tiny Anomaly patient in?
It stays calm at the window, then turns hostile once checked in. It can also arrive during the Ambulance Event mixed in with genuine victims โ size-check ambulance patients too.
