You can obtain the Island Lei on Club Penguin Rewritten in celebration of the Water Party by using the code SUMMERLEI! The code was released very recently but gives you a really cool item, the first ever lei!
To redeem your code, log into your account and click “Unlock Items Online”. Select that you have a code and enter the code. The item will then be added to your inventory! Be sure to do this soon as eventually it will no longer work.
I’m actually really pleased that a lei has been added to Club Penguin Rewritten, so it’s pretty cool to see this code be released! Make sure you claim it soon before it expires. Thank you for reading!
