There are few mascots as enduring as Hello Kitty. And like plastic in the ocean, I'm sure that one day she will outlast even us. Speaking of which, have you heard that the Under the Sea celebration is returning in Hello Kitty Island Adventure?

Yes, Island Adventure, which is available on Apple Arcade, is set to see the return of a fan-favorite celebration. The Under the Sea event will take you, well, beneath the sea. Running from May 29th to July 3rd, you'll be challenged to collect Mermaid Scales through a bubble obstacle course, which you can then exchange for aquatic-themed outfits, decor, and new scuba gear.

But that's not all! The latest major content update for Hello Kitty Island Adventure is also on the way. The Biggest Challenge lives up to its name, taking you on an epic ride up Icy Peak—with new activities and a reveal that promises to shock fans.

These two major updates promise not just summer-themed fun but also some surprisingly icy surprises. It's no surprise that Hello Kitty Island Adventure has become so popular, available exclusively on Apple Arcade.

The Sanrio characters have fueled an astonishing amount of merchandise, including mobile content. With the recent release of Hello Kitty Friends Match, it doesn't look like Hello Kitty and her friends' dominance on mobile will end anytime soon.

But if Hello Kitty isn't quite your thing, why not go Off the AppStore with Will Quick and discover new, exciting releases not available on Google Play or the iOS App Store? This time, it's the aptly-named, furious fighting game Fruits of Fury—how could anything with a carrot wielding a katana be bad?
