One appreciated feature in that many cozy games often leave out is the ability to fast travel. While listening to the little pattering of feet in Animal Crossing adds to the overall relaxing experience, ’s map is simply too large for walking exclusively to be anything more than an inconvenience.
For this reason, you will be able to find a surprisingly large number of mailboxes scattered around the map, which may be used as fast travel points, but only after being introduced to Cinnamoroll and activating each fast travel mailbox individually.
Once activated, you can fast-travel at any point, straight from the map. The quest to unlock fast travel is one of the first interactions with the notable Sanrio character, Cinnamoroll.
To find Cinnamoroll, you will first need to unlock the Spooky Swamp by completing the "" quest with Chococat and finding all the Yellow Crystals.
Once inside Spooky Swamp, head to the northern end of the area to find Kuromi and give her My Melody's welcoming gift, which should be enough to level up her friendship and unlock the "" quest.
