Route around him
Keep hallways clear and move around Slimebert rather than trying to pass through him. He can eat players and make patients faint.
How to Deal With Slimebert in Animal Hospital
Survive the Slime Shift by routing around Slimebert, protecting patients, and using the Fire Extinguisher only as a temporary escape tool.
Quick answer: Do not try to defeat Slimebert. Keep your distance and finish the Slime Shift: he leaves when the shift ends. A Fire Extinguisher can stun him briefly, but it will not remove him. If he catches you, the initial hit costs 20 Sanity and digestion continues draining 3 Sanity per second.

Verified Slimebert Mechanics
| Signal | What it means now |
|---|---|
| Slimebert is live in the Hazmat update | Multiple current gameplay sources reproduce the same Slime Shift encounter: Slimebert checks in, enters the hospital, and roams while green slime covers the building. |
| The danger and counter are reproducible | Getting too close lets Slimebert eat players and patients. A Fire Extinguisher temporarily stuns him, but does not despawn or defeat him. |
| The shift ending removes him | Slimebert and remaining slime disappear when the Slime Shift is completed. The safe objective is survival and patient protection, not combat. |
How to Survive the Encounter
This is a player-task guide built from repeatable live-game behavior. Follow the confirmed response below, while treating the remaining edge cases separately from the core strategy.
Stun only to create space
Use the Fire Extinguisher when Slimebert blocks a route or closes on a player. The stun is temporary, so leave immediately instead of standing nearby.
Finish the Slime Shift
Keep admissions and treatment moving while the Hazmat workers clean. Slimebert leaves automatically after the shift, and Sam can appear afterward.
Edge cases still being checked
- The exact first Slime Shift is randomized within the current Shift 12-23 window.
- Slimebert is documented as a special enemy and a Journal anomaly entry; he is not handled through the normal patient rejection flow.
- Interactions such as eating Ghosts or Hazmat workers may be harmless edge cases or update bugs and should not be used as the main strategy.
Common mistakes to avoid
- Trying to kill Slimebert instead of completing the shift.
- Treating the Fire Extinguisher stun as a permanent removal.
- Standing close after the stun and taking the 20-Sanity grab.
- Ignoring patients in Slimebert's route, which can leave them fainted.
