Quick answer: The Mimic is among the experiences identified in current reporting about Roblox’s upcoming Halloween event, The Hollow, and Roblox’s October 17 social posts reportedly spotlight Hiachi. The event date shown in the teaser is October 22, 2026. As of October 20, Roblox has not published a verified, complete The Mimic-specific quest walkthrough, reward list, or exact opening time in the sources reviewed here. Returning players should prepare for The Mimic’s horror gameplay, but wait for the live event instructions before assuming old Halloween tasks or rewards have returned.
The useful distinction is between what is known about The Mimic itself and what still needs to be confirmed inside The Hollow. This guide separates those points so players can spend launch day playing rather than chasing unverified reward claims.
What is confirmed before The Hollow opens?
Roblox’s teaser points to Thursday, October 22, 2026. Current reporting on Roblox’s October 17 Instagram posts identifies nine participating experiences, including The Mimic, and says the post associates Hiachi with the event. That is a useful clue about the crossover’s character theme, but it is not a quest guide. A character teaser does not by itself confirm a mission, badge, currency amount, reward item, or required chapter.
- Event date: October 22, 2026 is the date shown in the reported teaser.
- Character to watch: Hiachi is the character highlighted for The Mimic in current coverage of Roblox’s social posts.
- Exact opening time: Do not rely on a time-zone graphic or countdown from a third-party site unless it matches Roblox’s live event listing.
- Quest steps and rewards: Confirm these in the live event hub or an official developer announcement after the event opens.
- End date: Treat it as unconfirmed until Roblox publishes it.

Returning to The Mimic: what to remember
The official The Mimic experience by CTStudio describes its stories as horror inspired by Japanese history and urban legends. Its Roblox page warns players about flashing lights, loud noises, and jumpscares. If you have not played in a while, plan for atmospheric exploration and sudden scares rather than a quick, low-pressure collection game.
- Use audio carefully. Headphones can help with environmental cues, but lower the volume if loud effects are uncomfortable.
- Relearn your controls. Check the current in-game instructions on your platform instead of assuming every control or interaction is unchanged.
- Read objective text. Puzzle clues and interaction prompts can be easy to miss while rushing through a familiar area.
- Play with a reliable group if you prefer. Agree on who tracks clues and who checks side paths so teammates do not repeatedly split up.
- Expect changes. Updates can alter maps, interfaces, or event access. Use what the live game shows you, not an old walkthrough alone.
Do not assume 2025’s Halloween tasks have returned
The Mimic took part in Roblox’s 2025 Halloween Spotlight, where coverage documented Halloween Trials Part I and Nightmare Circus as event modes. That history is useful because it shows the game has previously supported a cross-experience Halloween event. It does not prove that the same modes, quest order, Rune requirements, or rewards will be reused in The Hollow.
When the new event goes live, look for an explicit event marker, a new objective in the game interface, or a direct link from Roblox’s hub. If an old guide tells you to collect a particular item, unlock a specific mode, or complete a multi-stage sequence, treat it as a guide to the old event unless the 2026 instructions match.
A practical launch-day checklist for The Mimic
- Open Roblox from the official app or website and navigate to The Mimic through its official experience page.
- Check The Hollow’s live hub for the latest participation details and the correct entry route.
- Read the quest text before starting. Record any required chapter, mode, item, or completion condition.
- Take a screenshot of the objective if you are playing with friends or expect to return later.
- Complete one task at a time and verify that the game registers progress before leaving the server.
- Check the reward inventory or event tracker after completion rather than assuming a badge automatically means every reward has been granted.
- If a task fails to register, re-read the requirement and check for server or game updates before repeating the whole route.
This checklist is deliberately practical rather than speculative. Until the live instructions are available, no one should present a guessed sequence as the confirmed The Hollow walkthrough.
Gameplay references that may still help
Older The Mimic guides can help explain how the game communicates interactions, but they should be used as background rather than as proof of current event requirements. For example, earlier chapters have used environmental objects and on-screen prompts to signal puzzle interactions. If you reach a puzzle during The Hollow, follow the live objective text and verify the required interaction in your current session.
Official sources to check
- The Mimic on Roblox — the experience page and current game access.
- Roblox — use the live event hub and official announcements for current requirements.
- Roblox on X — check for direct event updates and schedule changes.
- Roblox on Instagram — check the original character posts discussed in current event coverage.
We could not independently verify a stable, direct URL for the specific Hiachi Instagram post during this review, so this article links to Roblox’s official account rather than inventing a post embed. The official accounts and live hub should take priority over reposts and fan-made countdown pages.

What should returning players do first?
Open the official game page, review the current controls and objective text, and check The Hollow’s live hub. Do not spend time grinding a rumored quest until its requirement appears in the game or an official announcement.
Are the images in this article from The Hollow 2026?
No. The images are older The Mimic gameplay or 2025 Halloween Spotlight references and are captioned as historical context. They are not presented as footage from The Hollow 2026.
