Hello Kitty's 50th Anniversary
Hello Kitty's 50th Anniversary was an 
Event in 2024 that celebrated the 50th Anniversary of Hello Kitty. It was preceded by the Spooky Celebration and was the twenty-third available event in-game. The Hello Kitty's 50th Anniversary event ran from October 19, 2024, until the end of November 15, 2024.
In 2025, most of the content was made part of the Interlude of Dreams, but some returned during Hello Kitty's Birthday Celebration. The current purpose of this page is to explain what content was divided into each. (For information on the 2024 event, refer to the Archive page.)

Returned with Hello Kitty's Birthday Celebration
The 
Bowblossom returns with 
Hello Kitty's Birthday Celebration because the flower mimics Hello Kitty's iconic bow, which is strongly associated with her image.
Hello Kitty Collectible Cards
The 
Hello Kitty Collectible Cards are unlocked by the "Capering Cards" quest, which became a regular, unlockable quest after October 31, 2025. While the initial release was timed to the birthday celebration, the quest does not require participation in the birthday.
Collecting all the cards unlocks the associated rewards:
50th Anniversary Gold Bow
50th Anniversary Gold Dress
50th Anniversary Gold Tophat
50th Anniversary Gold Tuxedo

Notes

- ↑ The
50th Anniversary Balloons were distributed through a Sunblink Mail on October 23, 2025, due to a bug preventing them from being bought at the Interlude of Dreams event stand.
