Green Slime in Animal Hospital: floor and bed spread, hold E to clean, Sanity cost on large patches, and movement block.

Last updated: 2026-06-19

Slime Spread Behavior

Green Slime or sludge spawns on floors and hospital beds, spreading slowly to limit movement. Players and patients crossing patches may suffer Sanity loss or movement hindrance depending on patch size. Larger slime pools cost bigger Sanity hits when cleaned—community guides warn cleaning huge spreads hurts more than small puddles.

Environmental hazard, not admit-based. Appears any Shift, any wing. Often overlooked during Ambulance when runners sprint past and accumulate Sanity tax.

Hold E to clean interact until patch gone. Multiple players can prioritize different patches in co-op.

Cleaning Protocol

Clear slime near check-in paths first so shutter player rotates safely. Then treatment room floors before placing fainted patients on beds—slime on bed slows care.

Small patch: quick E hold. Large patch: sip Coffee before cleaning or assign high Sanity player.

Do not clean mid Skinwalker chase—survival order matters.

Patients and Slime

Patients pathing through slime may delay treatment timers indirectly. Clean before critical escorts when possible.

Fainted body drag across slime slows sixty-second fainting window—route around or clean first.

Bed Monster grab zones worse near slippery floors—combined room hazards teach map awareness.

Co-op Cleaning Rotation

Assign "slime runner" during Ambulance down times between admits. Not everyone job unless you are that runner.

Call patch location: "Slime Room 2 bed" for targeted response.

Extinguisher player sometimes doubles as slime cleaner when no fire active—tool loadout synergy.

Sanity Tradeoffs

Ignore tiny hallway patch if rushing critical patient—accept minor loss versus timer fail.

Massive lobby patch before Shift start worth cleaning during calm—prevents stack later.

Doctor does not heal from cleaning—no passive reward, only prevention.

Common Mistakes

Shooting or tasering slime. Trying to jump over forever—patch remains for teammates.

Cleaning during Ceiling Monster without looking down—double drain if camera tilts up.

Forgetting beds can hold slime—patients appear to glitch when bed covered.

When reviewing slime during a busy Shift, pause check-in if an emergency notification appears. Cross-check Shutters, CCTV, and appointment paperwork before admitting anyone related to this topic. A single verified mistake here costs more Sanity than a cautious extra ten seconds at the desk. (enemiesslime-0)

Frequently asked questions

How do I remove Slime?
Hold E on the patch until cleaning animation completes.
Does Slime hurt Sanity?
Large patches cost more Sanity to clean than small ones.
Can Slime appear on beds?
Yes. Clean beds before placing patients when possible.
Do weapons work on Slime?
No. Use E interact cleaning only.
Does Slime spread?
Yes, slowly across floor or bed surface.
Should I clean during Ambulance?
Only if blocking critical paths—prioritize patients first.
Is Slime tied to anomalies?
No. It is a random environmental hazard.
