Animal Hospital Night Shift The Hazmat Team Arrives

The Hazmat Team Arrives is the second major post-launch content drop for Animal Hospital (Anomaly) on Roblox after Harlow’s Favorite (July 2026). Community sources document a promotional event window roughly July 25–27, 2026 with a secret slime shift, Hazmat NPC convoy, lobby Journal, new Firefighter class, hireable Sam, Tiny Anomaly, and multiple cosmetic skins. This page separates event-window-only UI from permanent mechanics that remained in live builds after the banner closed — all labeled community-compiled unless cross-verified on the Roblox game page.

For gameplay walkthroughs, read Hazmat Slime Shift, Journal Guide, and the expanded Patch Notes section. Desk players should refresh Anomalies for Slimebert and Tiny Anomaly tells.

Hazmat Team Arrives update overview

Lobby Journal (permanent)

The Journal appears below Classes in the lobby and tracks:

• Anomalies encountered in live shifts
• Characters and NPC interactions
• Achievements and milestone stamps

Completed entries grant Animal Coins. Several anomaly pages require letting the entity check in first — a risky unlock pattern documented in Journal Guide. The Journal does not replace wiki checklists; it pays currency for in-game discovery.

Secret slime shift (community-compiled)

During slime shifts the hospital covers in green slime. Slimebert (community name) roams halls, swallows players for 20+ Sanity loss, and returns after fire extinguisher knockback — extinguishers cannot permanently kill Slimebert.

Containment form workflow:

1. Shift generates slime hazard and Slimebert patrol
2. Team completes containment paperwork stamp (community sequence)
3. Hazmat team NPCs arrive and assist scrubbing main corridors
4. Pressure eases but standard patient timers continue

Full tactics: Hazmat Slime Shift guide.

Firefighter class (permanent)

Firefighter costs roughly 1,100 Animal Coins (community-compiled):

• Elephant-like silhouette (community cosmetic description)
• Auto-recharging blue fire extinguisher in inventory at shift start
• Level perks: Sanity immunity to fire tiles and Sanity recovery when extinguishing fires (community-tested)

Meta placement: strong A to S tier for hazard and slime nights — see updated Class Tier List. Synergizes with free shop extinguisher on non-Firefighter roles.

Sam NPC hire (permanent)

After the event, Sam is hireable in lobby for about $250 cash (community-compiled). Sam persists and helps with:

• Slime cleanup on special nights
• Secondary anomaly assistance (community reports vary)

Sam does not replace player extinguisher duty — budget hire after Shift 3+ cash flow stabilizes. Profile: Characters.

Tiny Anomaly (permanent entry)

Tiny Anomaly spawns at miniature size — appears cute on camera, turns hostile after check-in. Desk players should shutter reject unless farming Journal pages. Encyclopedia entry: Anomalies.

Cosmetic skins (community-compiled list)

Reported skins and variants from the Hazmat window include:

• Banana Intern
• Detective Intern
• Fluffy Nurse / Maroon Nurse
• Old School Fox Head Nurse
• Noir Secret Agent / Agent Blueberry Secret Agent

Skins are cosmetic — they do not change anomaly tells or Shutter logic.

Shift 100 secret cutscene (unverified detail)

Community threads mention a Shift 100 secret cutscene possibly tied to endless progression or Hazmat flags. Treat as community-compiled rumor until multiple independent videos confirm triggers. Not required for Journal completion or Firefighter unlock.

Relationship to Harlow’s Favorite

Harlow’s Favorite (July 10–12, 2026) added Scanner, Mint Tea, Deployable Camera, and Security/Secret Agent kit changes. Hazmat stacks on that baseline:

• Journal adds Animal Coin income beyond shift payouts
• Firefighter complements fire events documented in Events Guide
• Stalker photography behavior from Harlow still affects desk layers during slime visibility

Re-read Patch Notes for the combined timeline.

Upcoming — New Update Aug 8–11, 2026 ET

Roblox event metadata and community posts reference a “New Update” window August 8–11, 2026 Eastern Time. As of August 3, 2026, mechanics, classes, and map changes are TBA — this wiki will expand after verifiable post-launch testing. Do not treat leaked Discord screenshots as finalized patch notes.

Loadout checklist after Hazmat

1. Open Journal — note missing pages before ready-up
2. Save 1,100 Animal Coins for Firefighter if you run Float/hazard
3. Hire Sam when cash exceeds ~$250
4. Refresh Hospital Map for slime choke points
5. Update co-op callouts for extinguisher knockback — not kill — on Slimebert
6. Bookmark Updates Hub for Aug 8–11 notes
