If you’ve just returned to Mermaid Isle for its August 2026 re-release, don’t forget to check the code menu before you start spending your Pearls.
There are currently two new codes tied to the re-release: ReefRefresh and SummerSplash. One gives you Pearls to spend around the Isle, while the other unlocks a cosmetic reward.
I’ve gone through the available codes and separated the current ones from the older rewards, so you can quickly see what is actually worth trying.
Mermaid Isle Codes [Re-Release] (August 2026)
Here are the codes currently associated with the August 2026 re-release:
| Code | Reward |
|---|---|
| ReefRefresh | 2,500 Pearls |
| SummerSplash | Summer Splash: Blue Lagoon |
Both codes were added with the August 8, 2026 re-release, so these should be the first two codes you try.
If you’re starting over or joining Mermaid Isle for the first time, ReefRefresh is particularly useful because 2,500 Pearls gives you a decent head start for buying cosmetics and other items.
The SummerSplash code is also worth claiming even if you aren’t interested in the Pearl reward, since the Blue Lagoon cosmetic is free once the code is redeemed.
Mermaid Isle Codes That May Still Be Worth Trying
Mermaid Isle has had a large number of codes over its previous updates. Some code lists still report older codes as active, while the game’s own code data can change as updates roll out.
If you’re seeing an older code listed elsewhere, you can try it, but don’t be surprised if it no longer works:
- GreedyLionfish
- Elegy
- Viscoria
- ThankYou50k
- HeartfeltUpdate
- ValentinesDay
- SealriouslyDevs
- SelkiesHymn
- SeasonOfMyths
- SeaFairyPearls
- FrilledScammer
- SkeletonScammer
- HalloweenEvent
- CursetideNight
- DailyFix
- FreeTangsForAll2
- GiveMeMyPearlsBack
- BugShutDown
- DolphinsComeBackSoon
- FreeTangsForAll
- Part2
- RejoinAfterClaimingThisCharacterSlotCode
- DarkFantasea
- LightFantasea
- SOULSONGGLOW
- 2MVISITS
I wouldn’t rely on this older batch for your August 2026 start, though. The two re-release codes above are the ones you should prioritize.
How to Redeem Mermaid Isle Codes
Mermaid Isle doesn’t put the code box directly in the middle of the screen, so it can be easy to miss if you’re new.
Here’s where to find it:
- Join Mermaid Isle on Roblox.
- Open Settings using the gear icon.
- Scroll down toward the bottom of the settings menu.
- Find the Codes section.
- Enter your code into the redemption box.
- Press the Redeem button.
- If the code is active, your reward should be added immediately.
Make sure you enter the code exactly as written. Mermaid Isle codes are case-sensitive, so don’t change the capitalization.
For example, enter:
ReefRefresh
rather than:
reefrefresh
If a newly released code isn’t working, try leaving the server and joining again before assuming the code has expired. A fresh server can sometimes have the latest version of the game.
What Do Mermaid Isle Codes Give You?
Most Mermaid Isle codes have historically been used to hand out Pearls, although the developers have also used codes for cosmetic items, character slots, and temporary bonuses.
Pearls are particularly useful when you’re starting out because you’ll eventually want to spend them on different customization options. Mermaid Isle has a huge selection of tails and other cosmetics, so free currency can disappear surprisingly quickly if you start buying everything you like.
That’s why I’d recommend holding onto at least some of your Pearls when you first start playing. Explore the Isle first, see what’s available, and then decide what you actually want to buy.
Expired Mermaid Isle Codes
The game has received quite a few event and milestone codes since its original release. Most of the older ones are no longer active.
Here are some of the better-known expired codes:
| Code | Previous Reward |
|---|---|
| 1MVISITS | 1,000 Pearls |
| CorruptGoddes07 | 1,500 Pearls |
| BUGGYUPDATE | 1,000 Pearls |
| HASHTAGBLESSED | 20 minutes of Divine Blessing |
| 500KVISITS | 500 Pearls |
| UPDATE1 | 1 Character Slot + 10 minutes of Divine Blessing |
| 100KVISITS | 250 Pearls |
| Release | 250 Pearls + Radiant Tide Swimmer: Opal Tail |
There are even more old event codes from previous versions of Mermaid Isle, but there’s little point filling the active-code section with rewards that players can no longer claim.
If an old code doesn’t work, that’s usually a sign that the developer has removed it rather than something being wrong with your account.
Why Isn’t My Mermaid Isle Code Working?
There are a few reasons a code can fail.
The code has expired
This is the most common reason. Mermaid Isle has released codes for events, updates, milestones, and temporary promotions, so older codes don’t necessarily stay available forever.
You entered it incorrectly
Check every letter before trying again. Since codes are case-sensitive, capitalization matters.
You’re on an older server
If the code was just released, your current server may not have received the latest game update yet. Leave and join another server, then try the code again.
There are extra spaces
If you copied a code from another website or social post, make sure you didn’t accidentally copy a space along with it.
The code has already been redeemed
Most codes are intended to be claimed once per account. If you’ve already used it, entering it again won’t give you another reward.
How to Find More Mermaid Isle Codes
The easiest way to keep up with new codes is to watch the game’s official community channels and pay attention whenever a major update or event arrives.
New codes are most likely to appear around things like:
- Major game updates
- Re-releases and revamps
- Seasonal events
- Visit or player milestones
- Bug fixes and server issues
- Community celebrations
- Developer announcements
The August 2026 re-release is a good example of this. ReefRefresh and SummerSplash were introduced alongside the game’s return, giving players an immediate reason to check the code menu.
When Will More Mermaid Isle Codes Be Released?
There isn’t a fixed schedule that guarantees a new code every week or month.
Instead, codes tend to show up when there’s something worth celebrating or when the developers want to give players a little extra reward. Major updates, seasonal content, milestones, and unexpected issues are all possible reasons for a new code.
So if Mermaid Isle receives another significant update, it’s worth checking back here afterward.
The August 2026 re-release is a great time to jump back into Mermaid Isle, especially if you missed the game during its earlier updates.
For now, start with the two re-release codes:
- ReefRefresh — 2,500 Pearls
- SummerSplash — Summer Splash: Blue Lagoon
Redeem them before doing anything else, then you can get back to exploring the underwater world, finding collectibles, customizing your mermaid, and deciding where you want to spend your free Pearls.
I’ll keep the list focused on codes that are actually useful instead of making you scroll through dozens of old rewards just to find the latest ones.
