Stalker

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.
