Animal Hospital, made by Roblox creator Roytt under the "Animal Anomaly" group, is not the calm vet-clinic sim its name suggests. It's a co-op survival-horror "spot the impostor" game: you work a night shift screening patients, and some of them are monsters in disguise.

The honest answer, source-checked, plus where to watch for a future code system.
How the Game Works
Solo or co-op with up to 3 players, you work a night shift as a receptionist/vet. Patients appear one at a time at the window — most are real animals, but some are anomalies: monsters disguised as ordinary animals. Screen each one using appearance tells, photo analysis, and security-camera feeds, then let real patients in or use a red shutter to keep suspicious ones out, all while managing a Sanity meter that must stay above zero. Your end-of-shift report awards Animal Coins and cash based on performance.
