There are a lot of events that take place in Hello Kitty Island Adventure. Here, you can learn about them all!
In this guide, we’ll take a look at all you need to know about the Happy Haven Days event in Hello Kitty Island Adventure. This will cover the unique item, as well as all potential rewards. Overall, this event is quite short, so be sure to log into the game and participate before it ends!
When Is The Happy Haven Days Event?
This year, Happy Haven Days takes place from March 17 to March 24. The first time you log in to the game during this event, a short cutscene will start with several of the residents; this means that you won’t accidentally miss the event.
The event stand itself is found to the right of the Resort Plaza, past where the Springtime Celebration kiosk is (these events will happen at the same time). You’ll know when you reach the location, because there will be a giant three-tiered cake in sight.
How To Get Rainbow Sprinkles
Rainbow Sprinkles are the main currency used during this event. This item is relatively easy to get; you’ll earn a few by completing daily quests, but you’ll also have a chance to find them by picking up items anywhere in the game.
Rather than just being limited to the Seaside Resort, Rainbow Sprinkles can come from anywhere. For example, we picked a few pumpkins in the Spooky Swamp and found Rainbow Sprinkles.
We noticed that finding Rainbow Sprinkles was pretty common when picking up Petals for the Springtime Celebration event.
Happy Haven Days Kiosk Rewards
At the giant cake kiosk, you can trade Rainbow Sprinkles for the following items.

Happy Haven Days first came to be in 2024, with a different set of rewards. Although you can’t trade these at the kiosk, you’ll still be able to find them at Tuxedosam’s shop, costing a variety of Rainbow Sprinkles, Fabric, Dye, or Ingots. Below, you can check out these items.

These items have a chance to appear in his shop, but it’s not guaranteed. Be sure to check back with him each day that the event is active.

What Is Confetti Cake?
By combining Rainbow Sprinkles and Flour in the oven, you’ll be able to make Confetti Cake, which functions like a normal baked good.
When you first start the event, it’s mentioned that you’ll be able to use the cakes on the stand. Currently, this seems to be bugged for many players including us at TheGamer. The cakes can’t actually be used at the cake stand, although Hello Kitty mentioned that it would be possible.
We’ll update this when more information comes out, but for the time being, bake a few Confetti Cakes and stock up on Rainbow Sprinkles.
You can also use Rainbow Sprinkles in other items. With the sprinkles, you can make confetti versions of a milkshake, mochi, boba, onigiri, and shaved ice.
