You never meet her. That absence is the point — every thread in this story eventually leads back to the twin sister who disappeared before the game even begins.
| Species | Rat — no confirmed description beyond a single photo |
|---|---|
| Role in the story | The disappearance every other thread leads back to |
| Animal Corp link | Worked for the Corporation, then vanished before the game begins |
| In-game presence | A photo in the Room 5 safe. That is all. |
Rattina is Ratthew's twin sister — described by him as "the smart one in the family." She worked for the Animal Corporation before she vanished, sometime before the events of the game.
There is no confirmed physical description of her beyond a photo — because as of this update, that photo is the only place she exists in-game.
Ratthew's farewell gift to the player is a key to a hidden safe in Room 5. Inside:
A missing Corporation employee, filed next to proof of a successful experiment that made a "shadow" see everything. The leading community theory is that the experiment created the Stalker — and that Rattina either fled it, was silenced by it, or was part of making it happen. The game has not confirmed any of the three.
The July 10 update added Liz, a journalist fired from Animal Corp's own news channel for reporting on the anomaly infection. Two women, one company, one still active and one missing — the pattern is consistent enough that most of the community reads Liz's arrival as connected to finishing what Rattina started.
Rattina is one of the 2 characters the game says actually worked for the Corporation. That is the strongest link anyone in this cast has — everyone else is connected through a person, an object, or not at all.
| Character | Link | What the game actually shows |
|---|---|---|
| 🐈 Liz | Worked for the Corporation | Worked for Animal Corp's news channel and was fired for telling the truth about the infection. |
| 🐁 Rattina ← this page | Worked for the Corporation | Worked for the Corporation, then vanished before the game begins. Her photo is filed in the Room 5 safe. |
| 🐭 Ratthew | Connected by family | No link of his own — his twin sister Rattina is the connection, and finding her is what his whole storyline is about. |
| 🦌 Dr. Harlow | Carries Corporation material | Carries a black suitcase stamped TOP SECRET in red — the same object that turns up in the Room 5 safe. |
| 🐰 Barney | No documented link | Nothing ties him to the Corporation. What he proves is separate and arguably worse: the screening scanner reads him green across all five visits. |
| 🦆 Officer Duckman | No documented link | The only character doing ordinary work for an ordinary reason. He is not investigating the Corporation — he is looking for one specific criminal. |
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.
Three carriers, no contents. Treat any account of what is inside as invention — the game has not shown it, and neither have we.
Sorted by what each of them does with what they have, the cast falls into four positions — and Rattina is in the one labelled knew, and is gone. It is the only position with one occupant, because it is not really a position — it is an absence the other five keep pointing at.
| Character | What they know | What they do with it |
|---|---|---|
| 🐈 Liz Knows and tells you | That the infection is real, and that Animal Corp buried the story. | Tells you, and hands you a camera so you can gather the proof she was fired for trying to publish. |
| 🐭 Ratthew Knows and tells you | That a government is hunting him for what he uncovered, and that his sister disappeared into the same organisation. | Warns you to trust nobody in the building, then leaves you the key rather than the answer. |
| 🐁 Rattina Knew, and is gone | Unknown — whatever it was, it was worth disappearing over. | Nothing. She is gone before the game starts, and the only thing she leaves is a photograph in someone else's safe. |
| 🦌 Dr. Harlow Knows and does not say | Unclear, and that is the point. He carries Corporation material and has been seen outside the hospital talking to an animal in a hazmat suit. | Runs your tutorial, grades your shifts, and explains none of it. |
| 🐰 Barney Knows and does not say | What he is. He is the only character who knows he is an anomaly and behaves accordingly. | Asks you for coffee, a scalpel, and finally to hide him — never once explaining why any of it is necessary. |
| 🦆 Officer Duckman Does not know | Less than you do, by the time he arrives. He has a photograph and a name. | Asks his questions and acts on your answer — which is why the choice lands on you rather than him. |
Unknown, but the signals point that way: the developer keeps expanding the lore cast (Liz arrived barely two months after launch), Ratthew's storyline ends on her unresolved disappearance, and a fan-made Rattina UGC plushie already exists on the Roblox marketplace — real evidence the community wants her story finished. If she appears in a future update, this page gets rewritten the same day.
Ratthew's full arc — from anonymous rat to the source of the deepest lore reveal in the game.
Read About Ratthew →Not yet. As of July 12, 2026 she's lore-only — mentioned by her twin brother Ratthew, and shown only in a photo hidden inside the Room 5 safe.
Unconfirmed. She worked for the Animal Corporation and vanished. Her photo is filed next to proof of a 'successful experiment' that made a shadow 'see everything' — the community theorizes she ran from it, was silenced by it, or was part of it, but the game hasn't said which.
