Updated October 27, 2026: The Mimic Hoodie is tied to the Animal Hospital crossover quest in Roblox’s The Hollow Halloween event—not to the separate horror game called The Mimic. Reports describe a multi-shift hospital task, a photo hunt, and a sliding-picture puzzle. Roblox’s official event announcement confirms that The Hollow has quests and avatar rewards, but it does not publish every step of this partner quest, so the walkthrough below labels community-reported steps accordingly.
Open the official The Hollow experience on Roblox before following any event route.
Quick answer: How do you get the Mimic Hoodie?
Community walkthroughs report that players should enter Animal Hospital through The Hollow hub, finish the first shift, speak to the Hazmat NPC on the next shift, use the vacuum to collect photo pieces hidden in pink slime, solve the reception-area sliding puzzle, and return for a final conversation before claiming the hoodie from its display in The Hollow hub. These steps are reported by third-party guides, not laid out in Roblox’s newsroom announcement, so follow the current in-game prompts if your run differs.
Step 1: Enter Animal Hospital from The Hollow hub
Start from the official The Hollow hub and use its Animal Hospital portal to launch the event-linked version of the game. Make sure you are entering the crossover mode from the hub rather than opening an unrelated Animal Hospital session from search results. Complete the first shift’s patient-care tasks and keep progressing until the quest dialogue becomes available.
Step 2: Talk to the Hazmat NPC and collect photos
According to published community walkthroughs, the Hazmat NPC gives you a vacuum during the next shift. Search the hospital for pink slime puddles and use the vacuum on puddles that visibly contain photo pieces. Check the quest prompt or inventory as you go; do not assume every puddle contains a required photo.
Step 3: Solve the reception sliding puzzle
After collecting the required photo pieces, go to reception and interact with the sliding-picture puzzle. Reports indicate that the starting board can vary, so a single universal sequence of tile moves may not work for every player. Use the image on your own board as the reference, solve it carefully, then return to the quest NPC when the game allows you to continue.
Step 4: Finish the quest and claim the hoodie in The Hollow
Community reports say the quest continues into a later shift, where you speak with the Hazmat NPC again after completing the puzzle. Once the event quest is marked complete, return to The Hollow hub and look for the Animal Hospital reward display near its portal. Interact with the display to claim the Mimic Hoodie, then check your avatar inventory to confirm it was added.
Common problems and fixes
- The quest has not started: finish the initial shift and check whether the next-shift NPC dialogue has unlocked.
- You cannot find photo pieces: scan for pink slime puddles and prioritize those where a photo is visible; use the vacuum only when you have it.
- The puzzle moves do not match a guide: the board may start in a different arrangement, so solve the layout shown in your own game.
- The hoodie is missing: return to The Hollow hub and interact with the separate Animal Hospital reward display after the quest-complete prompt. Recheck inventory afterward.
- A website asks for your password or a download: do not provide Roblox credentials or install third-party tools to claim an event reward.
Is the Mimic Hoodie the same reward as The Amazing Liquefactive Bighead?
No. They are different reward routes. The Mimic Hoodie is reported as a partner-game quest reward from Animal Hospital, while The Amazing Liquefactive Bighead is associated with a separate Floor 6 puzzle route inside The Hollow hub. Do not follow a floor-puzzle guide if your goal is the hoodie.
When does The Hollow event end?
Roblox’s official announcement says players can continue collecting event rewards until noon Pacific time on November 2, 2026. The event also has a live finale scheduled for October 31. Because individual reward instructions can change or differ by account, confirm the quest state and reward display inside the official experience before the collection window closes.
Frequently asked questions
Is the Mimic Hoodie free?
Community walkthroughs describe it as an earned event reward rather than a Ticket-shop purchase. Confirm the display in the official hub and do not pay an outside seller to claim it.
Do I get the hoodie by playing The Mimic?
Not according to the reported route. The hoodie quest is tied to Animal Hospital through The Hollow. The separate game The Mimic is a different crossover and reward route.
Does every player get the same sliding-puzzle solution?
Community guides report that the board can vary. Solve the arrangement visible in your own session instead of relying on a fixed move sequence.
Where can I check the official event dates?
Read Roblox’s official The Hollow announcement and launch the official event hub. The newsroom confirms the event and general reward window, while the detailed quest route above is attributed to community reporting.
