Stalker
A tall, black, bunny- or rat-like creature with big eyes and a large toothy smile, similar in appearance to the Hiders.
Stalker is a tall, black, bunny- or rat-like creature with big eyes and a large toothy smile — similar in look to the Hiders — that randomly appears around corners and inside rooms in Animal Hospital (Anomaly), usually just once per run.
Room lights flicker and a sound plays when it spawns, and if you spot it, it vanishes behind a wall almost instantly, draining 10 sanity from anyone who looked.
On rare occasions it can even check in as a patient at the window with a glitch-effect application form.
Behavior
- A tall, black, bunny- or rat-like creature with big eyes and a large toothy smile, similar in appearance to the Hiders.
- It randomly appears around corners and inside rooms; when it spawns, room lights flicker and a sound plays.
- Once spotted it quickly vanishes behind a wall, draining 10 sanity from any player who looked at it.
- It has a small chance to check in as a patient with a glitch-effect application form; looking at it during this event costs 1-2 sanity per second.
- It appears only once per run under normal circumstances (very rarely more).
How to Respond
- There is no way to prevent its spawns; the main strategy is to take corners slowly or look slightly downward when turning so you don't make direct eye contact.
- If it rarely checks in as a patient at the window, take its photo to make it disappear.
Quick tips
- There's no confirmed way to prevent Stalker from spawning — it's a scripted, unavoidable encounter that happens roughly once per run.
- Take corners slowly and look slightly downward when turning instead of straight ahead, so you're less likely to make direct eye contact.
- If it flickers the lights and plays a sound nearby, be ready for it to vanish behind a wall the instant you spot it.
- On the rare occasion it checks in as a patient at the window, take its photo to make it disappear.
