Ratthew
A small black anthropomorphic rat, paranoid but kind-hearted, who reveals lore across several visits: he initially hides his identity, then reveals his name and warns the player to trust no one, then reveals people think he's an anomaly (he isn't) and expresses sadness about it, then finally says he must disappear because the government is after him, revealing he had a twin sister, Rattina, who worked for the Animal Corporation and vanished.
Ratthew is a small, black, anthropomorphic rat in Animal Hospital (Anomaly) who's paranoid but kind-hearted, and one of the game's main lore characters. Across several check-in window visits he opens up gradually: hiding his identity at first, then warning you to trust no one, then admitting people mistake him for an anomaly, and finally revealing he has to disappear because the government is after him — along with the reveal that he has a twin sister, Rattina, who worked for the Animal Corporation before vanishing.
Behavior
A small black anthropomorphic rat, paranoid but kind-hearted, who reveals lore across several visits: he initially hides his identity, then reveals his name and warns the player to trust no one, then reveals people think he's an anomaly (he isn't) and expresses sadness about it, then finally says he must disappear because the government is after him, revealing he had a twin sister, Rattina, who worked for the Animal Corporation and vanished. He hands the player a key and note before this final departure and does not return.
How to Respond
No combat interaction; the key he gives unlocks a safe behind a cat poster in Room 5 containing a photo of Rattina, a 'TOP SECRET' suitcase, and a note about an experiment referencing 'the Shadow'.
