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.
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.
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.
