Quick Links
Hello Kitty Island Adventurebrings you to a vast archipelago that you’re able to explore. At the start of the game, you will need to travel the old-fashioned way; running (and swimming) around to reach your destination. Thankfully, you’ll be able to eventually unlock a fast-travel system.
In this guide, we will take a look at how to unlock this fast-travel system, and where each point is located. Rather than traveling anywhere you want, you’ll be able to unlock and travel to mailboxes, which display on the map. First, let’s dive into the quest you need to complete in order to unlock these mailboxes.

How To Unlock Mailboxes
In order to unlock mailboxes, you will need tocomplete the quest Delivery Service.This quest will unlock when youbecome friends with Kuromi at level one.Once this happens, Kuromi will wait for you at a mailbox in the Spooky Swamp.
At this point, you’ll need todeliver a pumpkin to My Melody,and then bring back a plant for Kuromi. On the way back, Cinnamoroll will explain the mailboxes to you, whichyou can take back to the Spooky Swamp to deliver the plant.

Once this is done, fast travel will unlock! If you want to actually use the mailboxes, you will need to discover them first. This means that you won’t be able to teleport to an area that you’ve never been before.
All Mailbox Locations
Below, you can check out all mailboxes available for you to teleport to in Hello Kitty Island Adventure. Not all of these locations are available to visit from the start of the game. To unlock them, continue tocomplete quests and level up friendship with everyone.We’ve made a note if all mailboxes can be found by just exploring, or if quests/tasks need to be completed beforehand.
From the map, you’ll be able to see acomplete list of all mailboxes.Any mailbox in an area that you have explored but haven’t seen yet willdisplay as some question marks.This will help youkeep track of any mailboxes that you may have missed.
