Quick Links
As the name suggests,Hello Kitty Island Adventuretakes place on an island! As such, you’ll be spending a fair amount of time in the water. At the start of the game, you won’t be able to swim or dive; both of these will unlock. While the ability to swim unlocks quickly, you may be wondering how the heck to begin diving.
In this guide, we are going to take a look at how to dive in Hello Kitty Island Adventure. This will include the quests that need to be done in order to fully go underwater. Diving is rather important, as you’ll need to have access to it before visiting Hangyodon for the first time.
Updated Jun 23, 2025 by Jacqueline Zalace:Snorkeling is essential if you want to explore the Rainbow Reef in Hello Kitty Island Adventure. We’ve updated this guide with a bit more information on the snorkel, as well as some tips to help you snorkel as efficiently as possible.
How To Start The Deep Diving Quest
The snorkel is unlockedthrough the quest Deep Diving.To start Deep Diving, you’ll first need toreach friendship level six with Kuromi.If you don’t have a high friendship with her at this point,be sure to give her three gifts each day.Kuromi will gladly acceptpumpkins,which are found right near her. Additionally,Jack-O-Lanterns are a two-heart gift for her.
After reaching the right friendship level, speak with Kuromi. She’ll ask you to get her lost locket andlet you borrow her snorkel.The process of getting the locket is fairly easy, but afterward, Kuromi will take it back.
At this point,she’ll give you the Snorkel Planthat you will need to craft yourself.
How To Craft The Snorkel
To craft the snorkel, you’ll need the following items.
When you get them all,head to the crafting table near Chococatand make a snorkel! After, you’ll be able to use it to go fully underwater.
How To Get Rubber
Rubber is pretty easy to find. The material can befound on the first island,typically lying around trees. Rubber looks likelittle purple balls,so if you see one, be sure to pick it up.
How To Get Sparks
Sparks are a bit harder to get than the other required materials. To game one, you’ll need toreach friendship level four with Pochacco.Once you’ve done this, you can start the quest calledA Zipline Adventure.
By completing this quest,you’ll get the recipe for Sparks,which requirethree Light Stonesto make. Thankfully,this is an item that Kuromi gives you after you give her a gift,so you’ll definitely have enough to make some Sparks.
How To Get Iron Ingots
Iron can befound on Mount Hothead.Here, the material is found on the ground, looking like dark-red clumps with grey flecks on it. If you need even more Iron, you can also participate in aminigame in Gemstone Town that gives Iron as a potential reward.
When you have enough Iron ore,you can craft three into one Ingot.
How To Use The Snorkel
To use the snorkel, simply start swimming. On the right-hand side of the screen,you should see the snorkel icon along with some arrows pointing up and down.By pressing down, you’ll get lower into the water.
After you get the snorkel,you’ll be able tovisit Hangyodon, who lives underwater.The actual building he is in doesn’t have water in it, so once you’ve entered, you no longer have to worry about diving or stamina. There is also afast-travel mailboxright outside this area,so be sure to activate it!
Snorkeling And Stamina
The snorkellets you descend into the water,but the amount of time you’re able to remain underdepends on your current stamina.With a lot of stamina, you can descend quite far down and explore the sea floor. If you happen to run out of stamina, the UI will disappear untilyour character has finished swimming back up to the surface.
To increase your time underwater,we highly recommend working to increase your stamina.This is done by turning Stamina Apple Slices into full apples. If you want to go a bitfaster underwater on limited stamina,you can alsomake the Speedy Swimming Potion, which is made with some tofu.
How The Mermaid Outfit Affects Snorkeling
Another thing that will affect your snorkel experience is theMermaid Outfit.Through the quest called Comic Relief, you canobtain all three pieces of the Mermaid Outfit,which makes snorkeling underwater way easier.
When all three pieces of the suit are equipped,you will swim way faster, as well as use less stamina.The difference is quite impressive, so getting the Mermaid Outfit early is a good idea. Eventually, you’ll also be able to complete the questMermaidified Fashion,which makes youautomatically turn into a mermaid when entering the water(you won’t need to change).
