All Animal Hospital Roblox Anomalies

This is the full Animal Hospital Roblox anomalies reference: every disguised threat, character, and NPC documented for Animal Hospital (Anomaly), ranked and filterable in one table. Most patients who walk through the check-in window are perfectly normal, but a rotating cast of anomalies is mixed in among them, and telling the two apart is the entire point of the game. According to the game's own Fandom wiki, a handful of rules hold across almost every entry on this Animal Hospital Roblox anomalies list. First, anomalies cannot be stunned, knocked out, or incapacitated by any method — including setting them on fire — with two documented exceptions: the Mimic can be dazed by gunfire or a Taser (though it still counts as an anomaly, not a normal patient), and Barney is explicitly immune to both guns and Tasers. Second, the game gives players several independent ways to detect an anomaly instead of relying on guesswork: the Scanner tool reads a patient as either green (normal) or red (anomaly); photographing a patient who's hiding an anomaly produces visible static noise or distortion in the picture, even when the patient looks ordinary to the naked eye; and if a shift ends without the usual summary screen appearing, that's the game's own signal that at least one anomaly patient went unhandled. Third, a single patient isn't limited to one anomaly trait — the wiki documents patients that show more than one anomaly characteristic at once, so clearing one red flag doesn't automatically mean the patient is safe.

How to Detect Animal Hospital Roblox Anomalies

Beyond the Scanner and photo-distortion methods above, this Animal Hospital Roblox anomalies list groups entries by type and location so you can cross-reference a suspicious patient against where and when a specific threat is known to appear, rather than relying on memory alone.

Why Some Entries Share a Name With Another

A handful of names in this Animal Hospital Roblox anomalies list — Skinwalker, Shapeshifter, Wall Anomaly, Don't Look Up, Monster Emerging, and Lobby Creature — are the wiki's own redirect titles for another entry (Mimic, Hiders, Mass of Eyes, Tendril, and Waiting Area Creature respectively). They're kept here as separate, searchable rows because players look them up by those names, and each one links straight through to the entity it actually documents. A small number of entries are still marked pending verification, meaning their full behavior and response details aren't published here yet — see the about page for how that verification process works. For general strategy across every shift, start with the new-player guide, and for what to give a patient once diagnosed, see the treatments page.
