Complete The Mimic’s carnival games and relic puzzles, defeat Dimitra, then redeem the Children of The Hollow badge in the hub for the Hiachi Grin Mask.
The Hiachi Grin Mask is an exclusive avatar item in The Hollow, earned through The Mimic’s event challenge. Entering the challenge takes you out of the event hub and into The Mimic lobby, where you can start the carnival encounter.
Your completion badge leads to the mask claim back in the event hub. This guide covers the carnival games, relic puzzles, Dimitra fight, and final badge redemption.
How to get the Hiachi Grin Mask in The Hollow
Start in The Mimic, work through the carnival and relic rooms, face Dimitra, and finish your reward claim in the event hub.

Walk through the doorway labeled The Mimic to bring up the teleport prompt.

Part 2 – Complete the carnival games
Explore the fairgrounds while avoiding capture by Ronnie.
Finish the carnival attractions
Press F to turn on your flashlight, then inspect Ronnie the Clown at the large central jack-in-the-box. The posted warnings tell you not to interrupt Ronnie or touch his box; Ronnie’s challenge starts the carnival objective at 0/7. This first stage requires completing seven carnival games. Avoid being caught as you work through the attractions in this order, crossing the fairgrounds to reach Pop the Balloon before finishing at Ring Toss.

Part 3 – Collect the four relics
Search the mansion tent and its adjoining rooms for the relic puzzles. This second stage requires finding four relics.
Obtain the Moon Relic
Inside the mansion tent, approach the floating Moon Relic and use its Hold E to Obtain prompt. On each chart, click and drag the sun into alignment with the target circle, then release to lock its position. Finish the charts to earn the relic.

Obtain the Fate Relic
Follow the corridors to the dining room table carrying the Fate Relic prompt. The puzzle presents four symbol cards: memorize the highlighted card, track where it lands, and click that position. Complete five rounds to collect the Fate Relic.

Enter the mirror room and watch which wall mirrors display eye symbols. The eye statues stand on pedestals beside red wall writing; use Hold E to Light at the statues to enter your sequence.

Obtain the Star Relic
Find the room with stacked wooden chairs and glowing yellow stars, then approach the Star Relic on its back wall. On the constellation wheel, click and drag stars to rotate them until every star connects within the pattern. Complete six constellations to earn the relic; Orion’s Belt is one of the displayed puzzles.

Part 4 – Use the crystal ball and defeat Dimitra
The downstairs crystal ball presents a wish before the boss encounter.
