Yellow Rabbit Patient Guide
A yellow rabbit patient. Important: a corrupted look-alike of this rabbit appears as an anomaly, so compare carefully before treating. This page covers how to verify Yellow Rabbit before treatment, which anomalies imitate it, and the mistakes that get players killed on this baseline.
Appearance
Bright yellow/orange rabbit. The harmless version looks like an ordinary patient.
How to handle Yellow Rabbit
Treat normally ONLY if it shows no anomaly traits. See the Monster-Mouth Rabbit anomaly for the corrupted version to watch out for.
How to identify Yellow Rabbit
Work these in order. Each one is written for this specific patient rather than for the roster as a whole, because the feature that catches a fake Yellow Rabbit is not the feature that catches a fake somewhere else.
| Check | What normal looks like | Why it matters here |
|---|---|---|
| Mouth and teeth | An ordinary closed mouth with no visible teeth | This is the defining check for this patient. The documented corrupted version of this rabbit is identified by an oversized mouth, so the mouth — not the colour — is what separates the two. |
| Body colour | Bright, saturated yellow-orange | The colour is the reason this baseline is dangerous: it is the same colour as the corrupted version, so colour confirms the rabbit and tells you nothing about whether it is safe. |
| Expression stability | One steady expression that does not morph while you watch | A mouth that opens, widens, or reveals teeth as you observe is the documented failure mode here. |
| Eye pairing | Two eyes, matched in size and height | Mouth anomalies on this baseline are frequently accompanied by mismatched eye placement, so the eyes act as a second confirmation. |
| Clipboard photo | Photo shows a closed mouth | The photo freezes the mouth. If the photo shows teeth or an open mouth on an otherwise matching rabbit, the photo layer has caught it for you. |
| Camera feed | Standard rabbit proportions with matched ear length | A corrupted version can hold a normal mouth at the window and reveal itself on camera, so do not treat the window view as final. |
Anomalies that imitate Yellow Rabbit
Five confirmed anomalies can present in a way that overlaps with this baseline. The tell column is the specific comparison to make, not a general warning.
Crooked Face
Crooked smile, sharp teeth, and eyes set at different heights. The mouth is the shared tell with the corrupted version of this rabbit, so both checks land on the same feature.
Smiling with Creepy Eyes
A fixed oversized smile that does not match the calm baseline. Do not tase to test it — tasing can make the smile disappear and make the patient look clean.
X-rayed Face
Realistic teeth and small circular eyes that appear in only one expression. Watch the mouth through an expression change rather than at a single moment.
Incorrect Photo
Compare the photo's ear shape and muzzle against the patient. A photo mismatch on this baseline often keeps the yellow colour intact, so colour tells you nothing.
Mismatching Ears
Compare ear length between the window and the camera feed. This is the cleanest camera-layer check on a rabbit.
Treatment path for a normal Yellow Rabbit
| Step | What to do |
|---|---|
| Check the mouth before anything else | This patient's documented risk is a corrupted look-alike distinguished by the mouth. Make the mouth your first look, not your last. |
| Watch the mouth through a full expression change | Several anomalies only reveal teeth or a widening smile at certain moments. A single clean glance is not sufficient evidence here. |
| Confirm on the photo and the camera | The photo freezes the mouth and the camera catches changes the window hides. Both are cheap and both are decisive on this baseline. |
| Treat only after every check passes | If the rabbit shows no anomaly traits across the window, photo, and camera layers, treat it as a normal patient using the named symptom prompt. |
Mistakes that cost runs on Yellow Rabbit
- Clearing the patient because the colour matched. The corrupted version of this rabbit shares the colour exactly, which is the whole problem.
- Glancing at the mouth once instead of watching it through an expression change.
- Treating the rabbit and then checking it, when the entire point of this baseline is the pre-treatment decision.
- Tasing the patient to test the smile, which can suppress the tell instead of confirming it.
When you meet Yellow Rabbit
Yellow Rabbit is the highest-attention patient in the normal roster. Its page exists mainly to make one point: a patient can match the baseline on colour and still be the corrupted version, so this is the patient to slow down on even when the ward is busy. If you build one thorough checking habit, build it here.
What we verified
- Recorded with an explicit warning that a corrupted look-alike of this rabbit appears as an anomaly.
- The reference to the corrupted 'Monster-Mouth Rabbit' form appears in this patient's own record; that form is not currently listed among the 18 confirmed anomaly entries, so treat the mouth check as the reliable indicator rather than searching for a separate page.
- Cross-checked against all 18 confirmed anomalies: five imitators overlap with the mouth-and-eye region this baseline makes decisive.
This baseline was last re-checked against the live game on September 16, 2026. Last verified 35 days ago — re-check pending.
Yellow Rabbit FAQ
Is Yellow Rabbit dangerous?
The patient itself is a normal, treatable arrival. What makes it notable is that a corrupted look-alike exists, so a yellow rabbit that shows anomaly traits must not be treated. Treat normally only if every check passes.
How do I tell the normal Yellow Rabbit from the corrupted one?
The mouth. The normal version has an ordinary closed mouth with no visible teeth, while the corrupted form is identified by an oversized mouth. Colour cannot separate them, because both are the same bright yellow-orange.
Should I tase Yellow Rabbit to check if it is corrupted?
No. Tasing can make an anomalous smile disappear, which makes the patient look normal and removes the evidence. Watch the mouth at the window and on the camera feed instead.
What if the mouth looks normal but something else seems off?
Then run the remaining layers before treating. An incorrect photo, mismatched ears, or an unnatural body on camera are all sufficient on their own to reject, even with a clean mouth.
Is Yellow Rabbit the same patient as Orange Cat?
No. They are separate baselines. Yellow Rabbit is a rabbit with the corrupted-lookalike risk, while Orange Cat is a tabby cat whose tell is its stripe pattern. Species and clipboard photo separate them quickly.
