Now that the Month of Meh featuring Gudetama is coming to a close, Hello Kitty Island Adventure players on Apple Arcade will be heading underwater for a recurring event titled Under the Sea Celebration. From May 28 to July 3, players can pop bubbles and collect Mermaid Scales, which can be exchanged for various ocean-themed outfits and gear. This massive content update also brings additional, above-water features for fans of Sanrio's Hello Kitty Island Adventure to look forward to. Though Nintendo Switch and PC players will be able to join in soon, an official release date for the 2.6.1 update for those platforms has not yet been revealed.

Alongside Mermaid Scales, players will be able to experience The Biggest Challenge update. This update includes a new roller coaster ride at Icy Peak, a talent show in City Town, a brand-new type of flower to collect, and a number of additional quests that help immerse players into the world. The Icy Peak ride's entrance is shaped like the crocodile it is named after, Big Challenges, likely introducing some to one of Sanrio's lesser-known characters while also offering an exhilarating ride with other Hello Kitty Island Adventure visitors.

Additionally, those who own a PlayStation may be pleased to learn that there are plans to release the game on PS4 and PS5 before the end of 2025. Eager Sanrio fans will soon be able to spend time with villagers, give gifts to others, enjoy various quests, and even give Hello Kitty friends cabins they can decorate on Sony's console.
