Hello Kitty Island Adventure invites you to a beautiful archipelago waiting to be discovered. At the beginning of your journey, you’ll navigate the islands by running and swimming. Fortunately, you can soon unlock a fast-travel feature to make your adventures much easier.
This guide will reveal how to activate the fast-travel system and the locations of each accessible point. Instead of traveling at random, you’ll unlock specific mailboxes shown on your map, making it more convenient to reach various destinations. Now, let’s get started on the quest that allows you to activate these mailboxes.
How to Unlock Mailboxes
To unlock the mailboxes, you need to complete the Delivery Service quest. This quest becomes available once you become friends with Kuromi at level one. After this, you’ll find Kuromi waiting near a mailbox in the Spooky Swamp.
Next, you must deliver a pumpkin to My Melody and then return with a plant for Kuromi. During your return trip, you’ll meet Cinnamoroll, who will explain the function of the mailboxes. After this, you can return to Spooky Swamp to hand over the plant.
Once these tasks are complete, the fast-travel option is yours! Just bear in mind that you’ll need to discover each mailbox before you can teleport to it; you can’t jump to areas you haven’t explored yet.
All Mailbox Locations
Below is a rundown of all the mailboxes you can teleport to in Hello Kitty Island Adventure. While some locations are accessible from the start, others require further quests and friendship levels to unlock. We’ve indicated which mailboxes are available right away and which require tasks to be completed beforehand.
From the map view, you’ll see a comprehensive list of all mailboxes available. Areas that you’ve explored but haven’t yet discovered a mailbox will appear as question marks, helping you keep track of what you might have missed.
