There are a lot of quests available in Hello Kitty Island Adventure. Every quest is sorted into a category, such as friendship quests, which boost your friendship level with specific characters. The Island Mystery quest category involves all the quests that relate to the main story of the game.

Hello Kitty Island Adventure: Retsuko Character Guide
Retuko is a music-loving hothead found in Hello Kitty Island Adventure. Here, you can learn how to find and befriend her.
One main quest that you will be able to complete is Reef Revival, which tasks you with cleaning up the reef and restoring it to its former glory. In this guide, we are going to take a look at how you can complete this quest and ultimately unlock the Recycling Plant.
Requirements To Complete Before Reef Revival
In order to complete Reef Revival, you’ll need to complete the following two quests. We’ve also included the requirements for each of the quests.
Quest |
Requirements |
---|---|
Open The Nature Preserve |
Complete Power Up The Gate Friendship Level 2 with Keroppi |
Comic Relief |
Friendship Level 6 with Hangyodon |
In addition to this, you’ll need to be friendship level 11 with Hello Kitty. Once these two quests are complete and you are level 11 with Hello Kitty, Reef Revival will unlock.
How To Start Reef Revival
After completing the requirements for Reef Revival, you can find Keroppi standing at the dock just north of where Chococat is usually found (near the crafting table). After talking with him for a bit, you’ll learn that he is bothered by the trash that is in the water.
Hello Kitty will eventually show up; after a bit more dialogue, you’ll then be prompted to meet Keroppi at the “strange underwater plant”.
Where To Collect Trash
The strange plant in question is the Recycling Plant. You can head to Keroppi and Hello Kitty’s icons to the plant, which is just to the right of the Cozy Islands fast-travel mailbox.
Here, the two will discuss the plant, and then ask you to collect eight more pieces of trash (in addition to the two pieces that Hello Kitty gives you).
Trash is found pretty much everywhere in the water. By swimming around underwater, you’ll be able to spot more black trash bags. Simply swim up to one and grab it to stow it away in your inventory.
Trash can be found in the water prior to beginning this quest. If you happen to already have enough pieces, you can skip the searching step. Here at TheGamer, we already had enough trash, so when Keroppi asked us to find eight more, we had the option to say “I’ve already collected those!”.
Recycle Trash In Exchange For Coral Spores
When you have enough trash, interact with the plant to begin recycling. You can select the newly obtained trash in order to recycle it and obtain Coral Spores. After getting the spores, you’ll now need to find a place to plant them.
This is found nearby, so you won’t need to travel too far. Coral Spores will be explained to you, and then you can choose which variation you want.
How To Complete Reef Revival
After the spores have been planted, Kiki and Lala will make an appearance and gift you a Rainbow Reef Star Fragment. Once this is done, you will complete the quest! The Recycling Plant will now be unlocked, and you’ll also be able to use Coral Spores around the Rainbow Reef.
Once complete, you can continue on with other main story quests and come back to recycle if you need to.
How To Use The Recycling Plant
Above, you learned that the Recycling Plant takes trash, but it can also take tons of other items. In general, recycling trash will give you a chance to obtain Coral Keys (to open chests) and Coral Spores.
You’ll also be able to obtain a wide variety of dye pouches based on the color of the item. For example, if you recycle Bananas, you may get a Yellow Dye Pouch. Below, you can check out a list of every Dye Pouch color.
- Black
- Blue
- Brown
- Gray
- Green
- Indigo
- Orange
- Pink
- Red
- Violet
- White
- Yellow
Trash counts as a black item as well, so it may yield a Black Dye Pouch.
Dye Pouches can be used at the Clothing Dye Station in order to dye clothes in different colors. This station will need to be unlocked through the quest called Tuxedosam’s Dye Upgrade.
