Hello Kitty Island Adventure Under the Sea Event Appears Alongside 2.6

Sunblink announced a returning Under the Sea Celebration event for all versions of Hello Kitty Island Adventure, as well as update 2.6 for the Apple Arcade version of the game. The aquatic event starts tomorrow on May 29, 2025. Meanwhile, 2.6 is on mobile devices now ahead of an imminent release on the Switch and PC. There is also a trailer going over the update. 

The Under the Sea Celebration in Hello Kitty Island Adventure follows the Month of Meh event. It’s another one of those activities that involves collecting a certain type of item to turn in for cosmetics. In this case, it’s Mermaid Scales. As such, getting access to the mermaid clothes so you can go underwater ahead of taking part can be wise. However, it isn’t necessary since the scale are found in the Seaside Resort beaches and the area to turn them in is in the Resort Plaza hub. The 2025 cosmetics include scuba gear, which will be shown in the trailer for the event.

As for the 2.6 update for Hello Kitty Island Adventure, it involves Big Challenges and Icy Peak. It looks like a roller coaster is about to open on the top of the mountain. However, it also seems new additions are coming to Wish Me Mell’s meadow and Usahana’s City Town sections too. New dancing options seem to be available in this update. We seem to get to go to a performance hall, once it is built, too.

Hello Kitty Island Adventure is available for the Switch, PC, and iOS devices via Apple Arcade. PS4 and PS5 versions are on the way, though there’s no exact release date for them yet.
