Mermaid Isle lets players design a custom mermaid with tails, hairstyles, and ornaments while exploring an open ocean map. Pearls are the in-game currency used to unlock shop items, and codes are the fastest way to stock up on them for free.

How to redeem Mermaid Isle codes
Redeeming a code takes a few seconds once you’re inside the game.
A successful redemption adds the pearls or item directly to your account, and pearl totals update immediately in the shop menu. Cosmetic rewards like tails or accessories appear in your character customization inventory rather than being worn automatically.
Expired Mermaid Isle codes
These codes no longer work and will return an error if entered.

Where new Mermaid Isle codes get announced
New codes tend to follow map updates, bug-fix patches, and seasonal events like the current Reef Refresh update. The development team posts fresh codes in the “Update-logs” channel of the Mermaid Isle Discord server, and also shares announcements through the Mermaid Isle Roblox community.
Codes tied to specific events, such as Halloween or visit-count milestones, usually stop working once the next update ships, so redeeming pearl codes early is the safest way to avoid missing out on a reward before it rotates out.
