Earning and spending pearls

Tips

In short Pearls fund everything in the shop, and free sources can carry you a long way without spending Robux.

Every customization item in Mermaid Isle is bought with pearls. The 250 you get from joining the group and liking the game is a solid starting pile, and redeem codes — released with updates — add more over time.

Tips worth knowing

Redeem codes expire, so check for new ones whenever a major update drops.
Each code can only be used once per account, so there is no point trying the same code twice.
