Officer Mewmew’s medal challenges are organized by area: Sixth Street, Brant Street, Lumina Square, Ballet Twins Road, Rebuild Ridu!, Blazewood, and Port Elpis. Challenges can involve commissions, lost cargo trucks, helping Bangboo, or collecting H.I.A. Commemorative Coins. If a listed character or Bangboo is missing, check the in-game time and your story or Inter-Knot progress before assuming the task is unavailable.
Where to find Officer Mewmew’s medal challenges
Open the Officer Mewmew challenge list for the area you are exploring, then check which medal category remains incomplete. The broad area index covers these seven locations: Sixth Street, Brant Street, Lumina Square, Ballet Twins Road, Rebuild Ridu!, Blazewood, and Port Elpis.
The tasks are not all collectible hunts. Depending on the area, medals may require completing a commission, finding a lost cargo truck, helping a Bangboo, or collecting H.I.A. Commemorative Coins. Check the specific missing medal in the list so you can focus on its objective rather than searching the district at random.
What to check when an NPC or Bangboo is missing
- Check the time requirement. Some encounters are tied to morning, afternoon, evening, or midnight. Advance the in-game time to the period associated with the task, then revisit the encounter.
- Check story and quest progress. Some tasks become available only after advancing the relevant story or quest chain. For Sixth Street, the available guide notes that later tasks can depend on further story progress.
- Confirm the medal type. If the missing objective is coin-related, check the area’s H.I.A. Commemorative Coin progress; a coin medal is distinct from a commission or encounter task.
The Sixth Street Page 2 guide associates its later content with Inter-Knot Level 14 and Chapter 1, but this is a guide-reported context, not a universal unlock rule for every Officer Mewmew task. HoYoLAB guide
