Home Alone: Anomalies — The Hollow Event Quest Walkthrough

📖 5 min read · Updated 2026-10-30 · Fact-checked against community wiki & Steam discussions

Roblox's platform-wide The Hollow event runs October 22 – November 2, 2026, and Home Alone: Anomalies is one of the experiences with its own quest line. Finish it and you keep an exclusive UGC accessory plus a badge — but the quest asks you to survive a night with four crossover characters, two of which are built to bait you into opening the door.

This walkthrough covers the exact steps, each character's tell, how to protect your Sanity, and where the reward podium actually is. Verified against Sportskeeda's quest guide (October 26, 2026) and the event window listed on the Roblox Wiki. Independent coverage — not affiliated with Roblox or the developers.

Quick answer

Step	What to do
1	Open Home Alone: Anomalies and enter through The Hollow portal (solo or a party of up to 4)
2	Survive one night and meet all four crossover characters: The Inspector, Mimic, Demon, Werewolf
3	Keep Sanity up by avoiding jumpscares and finishing board chores (cleaning, washing dishes)
4	Return to The Hollow hub → elevator to Floor 4 → maze → secret room with the Home Alone portal
5	Interact with the podium next to the portal to claim the Anomaly Detection Rig and its badge

The quest completes on the night you have seen all four — you do not need to hunt for them, they arrive at the door on a schedule.

The four crossover characters

Character	Origin	When / tell	Correct response
The Inspector	Scary Shawarma Kiosk: The Anomaly	Arrives exactly at 3:00 AM; sweeps the house with a red vision light	Stay away from windows, crouch in a corner of an interior room and wait it out
Mimic	Animal Hospital (Anomaly)	A harmless-looking bunny at the door asking for a medkit	Deny entry — letting it in triggers an attack that guts your Sanity. Denying still counts for the quest
Demon	Demonology	Spawns inside the house, not at the door	Expect the jumpscare; it costs a chunk of Sanity, so pre-clear chores to bank Sanity first
Werewolf	Dead Rails	Arrives around 4:00 AM; storms in if admitted and hits hard	Deny it, or if it is already inside, run circles — it is extremely slow and gives up the chase

The Inspector and Werewolf are time-gated, so watch the in-game clock: if 3:00 AM passes and you never saw the Inspector, you were probably hiding too far from the windows and the check may not register. Stay in the house, keep line of sight to the front area, and let it complete its sweep.

How to keep Sanity alive

Sanity is the real resource in this quest, not health:

Do chores early. Cleaning and washing dishes from the objective board are the reliable Sanity top-ups. Bank a buffer before 3:00 AM.
Deny first, ask later. A denied visitor cannot hurt you. The only cost of denying a real human is a missed task, and this quest does not require you to admit anyone.
Hide from the Inspector's light, not from the house. Interior corners away from windows work; leaving the building does not progress the quest.
Do not fight the Demon. It is a scripted jumpscare; save your energy for the Werewolf, which is the only one you can outrun.

Solo is viable. The Hollow quest does not require four players — the party cap of 4 just makes the night faster, and more players means more chores completed per minute.

Claiming the Anomaly Detection Rig

The reward is easy to miss because it is not handed to you at the end of the night:

Finish the night with all four characters seen.
Return to The Hollow hub.
Take the elevator to Floor 4.
Walk the maze until you find the secret room holding the Home Alone: Anomalies portal.
Interact with the podium beside the portal.

That podium grants the Anomaly Detection Rig cosmetic (equip it from the Customize menu) and the matching "Anomaly Detection Rig" badge. If the podium gives you nothing, the quest did not register all four characters — replay a night and confirm the Inspector and Werewolf both appeared.

Event dates and what happens after

The Hollow closes on November 2, 2026. After that the portal and podium leave the hub, and the Anomaly Detection Rig becomes a legacy item — it stays in your inventory, but there is no second chance to earn it. If you are reading this after the window, the Home Alone endings library is the part of the game that stays relevant.

FAQ

Do I need a party for The Hollow quest? No. You can complete it solo; the 4-player cap only speeds up the night.

Does denying the Mimic fail the quest? No — denying counts toward progress. Letting it in is the mistake.

What time does the Inspector arrive? Exactly 3:00 AM in-game; the Werewolf follows around 4:00 AM.

Where is the reward? Not at the end of the night. Go back to the hub, elevator to Floor 4, maze, secret room, podium.

What is the reward called? The Anomaly Detection Rig — a UGC accessory plus a badge of the same name.
