Mochi Sticker Fusion

Fusion is how duplicate stickers become stronger. This page covers the confirmed flow and clearly marks what is not yet official.

Quick answer

Duplicate stickers can be fused to raise their tier. Fused (higher-tier) stickers grant better passive bonuses and improve your chances of finding rare decorations, collectibles and treasures.

The confirmed fusion flow

  1. Collect stickers through gameplay (see the Stickers page).
  2. Hold duplicates of the same sticker.
  3. Fuse the duplicates to raise the sticker's tier.
  4. Equip the sticker to benefit from its passive bonus.
  5. Repeat as you collect more — higher tiers improve rare-drop chances.

Requirements and results

The official description confirms the flow above but does not publish the exact requirements (how many duplicates per tier) or the resulting bonus values. Until those are confirmed in-game or officially, they are marked not yet verified.

Based on the official Steam listing (App 4957510), verified 2026-08-25. No fusion formulas, duplicate counts or bonus numbers are guessed on this page.
