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.
Prepare for the Slimebert route before the shift starts
The useful preparation is about keeping options open. Leave one inventory slot for the Fire Extinguisher, keep the treatment queue moving so patients do not accumulate in the waiting area, and learn the shortest route between the lobby, check-in window, and Medical Wing before the event begins. This is a routing problem inside a normal hospital shift, not a boss arena with a separate objective.
If you are playing with a team, assign one player to keep admissions and treatment progressing while the others watch the roaming path and clear blocked hallways. In solo play, make the same priorities explicit: open space first, a patient second, and the temporary stun only when it buys enough distance to complete the next task. The confirmed evidence supports this order; it does not support a special weapon, permanent trap, or secret removal input.
A route for a blocked hallway and a failed escape
When Slimebert blocks the direct route, do not walk toward him hoping the model will pass through. Back up to the nearest open room, use the Fire Extinguisher only when he closes the gap, and leave during the brief stun. Re-open the route from the side rather than stopping to watch whether he despawns. The source shows a temporary stun and the end-of-shift removal; it does not show a permanent defeat state.
If an escape fails and the grab begins, the documented cost is 20 Sanity at the initial hit followed by 3 Sanity per second during digestion. Treat that as a recovery signal: break away when the game allows it, restore Sanity when safe, and stop taking optional trips through his route. A failed escape is evidence that the route is unsafe, not evidence that a new counter should be invented from one clip.
What the evidence does and does not prove
This guide records the repeatable encounter, the temporary Fire Extinguisher stun, the patient danger, and the fact that Slimebert leaves when the Slime Shift ends. Those are the claims supported by the checked gameplay sources. The exact first-shift roll, unusual interactions with Ghosts or Hazmat workers, and any route that depends on a particular room state remain separate questions.
Use the source video as a checkpoint when the live build changes: compare the event cue, the slime-covered hospital, the roaming behaviour, and the end-of-shift cleanup. If a future patch changes one of those signals, update this page from a reproduced run instead of carrying forward a number or mechanic that no longer appears.

Frequently asked questions
Is Slimebert in Animal Hospital now?
Yes. Slimebert is a live special enemy in the Hazmat update and appears during a Slime Shift.
How do I get Slimebert out of the hospital?
Complete the Slime Shift. Slimebert leaves when the shift ends; there is no confirmed way to remove him permanently before then.
Does the Fire Extinguisher defeat Slimebert?
No. It briefly stuns him and gives you time to escape or clear a route, but he remains active until the Slime Shift ends.
What happens if Slimebert catches me?
The initial grab drains 20 Sanity, followed by 3 Sanity per second while you are being digested.
