How to Start The Hollow Challenge in Animal Hospital?

To begin, enter The Hollow Event Hub on Roblox and find the Animal Hospital portal. After that, walk through it and start a run in The Hollow Event mode. Your first objective is to keep the hospital running by checking in patients, taking them to their assigned rooms, and treating them as required.
You must survive the first shift because the special quest becomes available on Shift 2. So, continue completing your hospital duties until the next shift begins, then look for the Hazmat NPC in the seating area to move to the next part.
How to Collect All the Photographs in Animal Hospital?

When Shift 2 begins, look for the Hazmat NPC inside the hospital and interact with them. He will give you a vacuum cleaner, which you need to use to remove pink slime puddles containing hidden photographs. So, carry the vacuum while exploring the different rooms and corridors, and clean the slime on the floors wherever you find it.
However, be careful, as the Mimic can disguise itself as a patient. If it attacks you, rapidly press E to strike its pressure points and escape. So, keep searching until you have collected all photographs, then head to reception to complete the next objective.
How to Solve the Sliding Puzzle in Animal Hospital?

Once you have gathered the photographs, return to the reception area and look for the 3×3 sliding-tile puzzle mounted on the wall in front of the counter. The board contains eight movable tiles and one space.
Your goal is to rearrange the tiles until they form the complete picture. However, the arrangement can differ between players, so no single sequence works for every player.

After solving the sliding puzzle, continue running the hospital and completing your duties until Shift 3 begins. Once Shift 3 starts, find the Hazmat NPC again in the waiting area and interact with him to finish the quest.
This final interaction completes the quest and rewards you with The Hollow Animal Hospital Badge, along with the Pumpkin Intern class, 100 Halloween Cash, and 10 Tickets.
Afterward, return to The Hollow Event Hub and find the associated UGC display beside the Animal Hospital portal. Once you find it, interact with it to claim the Mimic Hoodie UGC as a reward.
