Special shift
Animal Hospital Roblox Hazmat Team Arrival
The Hazmat update adds a special shift where green fog and slime spread through the hospital while the cleanup team and Slimebert appear. Recorded runs show that the timing varies, so reaching Shift 12 does not guarantee an immediate trigger.

Signs you are in this event
- Green fog and slime begin covering hospital paths.

- Yario reached the slime shift around Shift 16 or 17.
- Another recorded run reported triggers at Shift 27 and Shift 12 in different sessions.

- A Journal for encounters and achievements that awards Animal Coins.
- The Firefighter class, Sam, Tiny Anomaly, and new or reworked skins.

Event FAQ
When does the Hazmat Team arrive in Animal Hospital Roblox?
Do not expect one guaranteed shift. The wiki connects the event to Shift 12, while recorded player runs observed it at Shift 13, around Shift 16 or 17, and as late as Shift 27.
How do I know the Hazmat special shift started?
Look for green fog, slime across hospital paths, Hazmat workers, and Slimebert moving through the halls.
