Every named face at the hospital is hiding something about Animal Corp and the anomaly infection. This is the lore side of the story — for shift-by-shift interaction guides, see the main wiki.

Every Animal Hospital character with their role in the story and their connection to Animal Corp

All six Animal Hospital characters, and what they know

Six characters have names and storylines. What actually links them is not the hospital — it is Animal Corp. Three of the six have a direct line to the Corporation, and the profiles below follow that thread rather than the gameplay.

🐈 Liz

Caracal-like creature, light-brown fur, dark downturned ears · the game's first interactive female character

Liz used to work for Animal Corp's news channel fired for telling the truth about the anomaly infection. She arrives around Shifts 11–12 with a UV camera she's willing to lend you — for a four-photo assignment. Burn a shot on the wrong target and she walks, calling you untrustworthy.

Rattina worked for the Corporation and vanished; Liz reported on it and got fired. Two women, one company — and now one of them is staking out the building its secret keeps leaking into. The community reads her arrival as the conspiracy's first real investigator going to work.

🐭 Ratthew

Small black rat, white muzzle, pink tail · recurring patient, explicitly not an anomaly

Ratthew's visits form a slow reveal: he introduces himself anonymously, warns you to trust no one in this hospital, and admits he chewed up classified experiment reports in Ron's office — and doesn't regret it. On his final visit he confesses he uncovered a government secret and is being hunted for it, mentions his missing twin sister Rattina("the smart one in the family"), and hands you a key.

That key opens a hidden safe in Room 5 behind a cat poster: inside is a photo of Rattina, a suitcase stamped TOP SECRET, and a note reading "The experiment was a success. The shadow now sees everything." — widely read by the community as the origin of the Stalker enemy.

🐁 Rattina

Ratthew's twin sister · lore-only, no in-game appearance confirmed as of this update

Rattina worked for the Animal Corporation before she vanished. The only trace of her is the photo in the Room 5 safe, filed next to proof of a "successful experiment" that made a shadow "see everything."

The leading community theory: the experiment created the Stalker, and Rattina either ran from it, was silenced for it, or was part of it. The game hasn't confirmed any of the three — but a fan-made Rattina UGC plushie already exists on the Roblox marketplace, which tells you how much the community wants her story finished.

🦌 Dr. Harlow

Orange muntjac deer, blue scrubs, "TOP SECRET" briefcase · your supervisor, appears every shift

Harlow grades your performance every shift and unlocks core features as you progress. But he carries the same TOP SECRET suitcase as Ron from Accounting and the one hidden in Ratthew's safe — and an anomaly version of him, hollow-eyed and blank, has been spotted through a lobby-window glitch.

He's also been seen stepping outside to talk with an animal in a hazmat suit before returning to work as if nothing happened. The July 10 update — named "Harlow's Favorite Update" — gave him a new model and new interactions, but stopped short of explaining any of this.

🐰 Barney

White rabbit-like creature, mustache, brown hat · confirmed anomaly and serial killer

Barney is polite, calls you "friend," and asks for small favors across five visits — coffee, a briefcase to hold, a photograph that reveals his true form: a wide, sharp-toothed mouth and hollow eyes. Tasers and guns do nothing to him.

When Officer Duckman arrives hunting him, the player chooses whether to hide him (reward: a second coffee machine) or turn him in (Duckman gets stabbed and Barney escapes). Either way, Barney is proof the hospital has been harboring exactly the kind of thing it's supposed to screen out.

🦆 Officer Duckman

Black duck, blue police cap · hunting Barney, not an anomaly

Duckman exists entirely in relation to Barney's storyline — he shows up with Barney's photo, asks if you've seen him, and his fate depends entirely on your choice. A straightforward cop in a hospital full of people who aren't what they seem.

The Animal Corp web, all six at once

Six profiles, sorted by how each one connects to the Corporation rather than by when you meet them. Two worked there. One is family to someone who did. One carries their briefcase. Two have no link at all — and those two are the ones the game makes you choose about, which is the pattern worth noticing before you read any single profile.

CharacterLinkWhat the game actually shows
🐈 LizWorked for the CorporationWorked for Animal Corp's news channel and was fired for telling the truth about the infection.
🐁 RattinaWorked for the CorporationWorked for the Corporation, then vanished before the game begins. Her photo is filed in the Room 5 safe.
🐭 RatthewConnected by familyNo link of his own — his twin sister Rattina is the connection, and finding her is what his whole storyline is about.
🦌 Dr. HarlowCarries Corporation materialCarries a black suitcase stamped TOP SECRET in red — the same object that turns up in the Room 5 safe.
🐰 BarneyNo documented linkNothing ties him to the Corporation. What he proves is separate and arguably worse: the screening scanner reads him green across all five visits.
🦆 Officer DuckmanNo documented linkThe only character doing ordinary work for an ordinary reason. He is not investigating the Corporation — he is looking for one specific criminal.

The briefcase nobody opens

One object shows up three separate times, and it is the same object each time: a black suitcase stamped TOP SECRET in red. It is never opened on screen.

  • Dr. Harlow carries one Visible from Shift 1, never opened on screen.
  • One sits in the Room 5 safe Filed alongside Rattina's photo and the experiment note.
  • Ron from Accounting carries one Same black case, same red stamp — on a character whose job has nothing to do with medicine.

Three carriers, no contents. Treat any account of what is inside as invention — the game has not shown it, and neither have we.

FAQ

  • How many named characters are in Animal Hospital?

    Six confirmed named characters with real storylines or lore: Liz, Ratthew, Rattina, Dr. Harlow, Barney, and Officer Duckman. Several minor NPCs (Shopkeeper Nurse, Lobby Cat, Lobby Bunny, News Bunny) round out the cast without dedicated storylines.

  • Are Barney, Ratthew, and Rattina connected?

    Not directly confirmed, but the evidence lines up: Barney is a revealed anomaly, Ratthew uncovers a hidden Animal Corp experiment, and his missing twin Rattina worked for that same Corporation. All three storylines point at one unresolved conspiracy.
