On 1 August 2025 Sunblink dated the large Hello Kitty Island Adventure expansion Wheatflour Wonderland. It reaches Nintendo Switch and Steam on PC on 18 September at $14.99. Apple Arcade players get it at no extra charge. A PS5 release was promised soon, and the game itself was set to arrive on PS4 on 5 August.

In the story Kuromi and My Melody spill a magic potion on flour at Hello Kitty's cafe and open a way into a wheat-flour realm of colored castles, ruins, and gentle creatures. The fairy Cogimyun asks players to restore the Wheatflour Guardians and unlock the Ancient Citadel, where a legendary treasure is hidden.

It is the biggest expansion since the game launched. Cogimyun has 35 friendship levels, each with its own quests and items; her brother Cogimyon and Ebi Fry join her. Wands can be crafted, customized, and used to turn into animals and objects and to solve new puzzles. Players also collect Guardian outfits, 100 Wheatflour Hearts to trade for rewards, and noodle recipes from ramen to spaghetti and meatballs.
