All Collectibles Guide — Moldwasher

Moldwasher features six major collectible categories: hidden drops in missions, stickers requiring precise spray removal, toys from garage batches, CDs and cassettes for the lo-fi music system, gachapon decorations purchased with coins, and hub cosmetic items displayed on walls and shelves.

Each category connects to specific achievements. To Infinity and Beyond requires all toys. Apply Directly to the Forehead covers all stickers. Rewind time! needs every cassette. Sushi! at the Disco asks you to play five CDs. Gamer Brain is the ultimate completion trophy for finding everything.

After every mission, the results screen shows a hidden drop counter such as 0/1 or 1/1. Any incomplete count means a collectible remains in that level. Hidden objects often sit beneath thick mold patches, inside containers, or in optional areas off the main cleaning path.

Do not rush missions if you hunt collectibles. Clean slowly, watch for visual hints like unusual mold shapes or sparkle effects, and replay immediately when the counter shows missing drops. Our Hidden Objects page lists known locations by mission.

Stickers appear as layers on surfaces—especially in the sticker fridge mission—and require precise stream removal before counting as collected. Toys spawn from garage toy batches and specific mission rewards. CDs unlock through lo-fi system cleaning and mission completion. Cassettes scatter across later areas for the Rewind time! achievement.

Visit the dedicated pages for Stickers, Toys and CDs, and cross-reference the Achievements list for exact unlock requirements and global completion percentages.

The hub gachapon machine accepts coins earned during missions—five coins per pull. Decorations customize your basement home with adorable items for walls and shelves. The achievement It's Not Gambling If You Know You're Gonna Win requires 25 gachapon purchases.

Decoration hunting is separate from mission hidden drops but equally important for 100%. Read our Gachapon guide for coin farming synergy with garage loops and mission replays.

Completionists should track four parallel goals: mission hidden drops during first playthrough, garage toy batches on every refresh, sticker and cassette backtracking using mission select, and gachapon pulls whenever coins exceed five. Use the results screen religiously—never leave a mission with 0/1 hidden drops unchecked.
