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.

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.
