How to Open the Heart of the Island in Fisch

The giant gate in the Sandcastle area, known as the Heart of the Island, can only be opened after collecting all seven colored Messages in a Bottle and completing their associated treasure hunts. Each bottle provides clues that lead to hidden dig locations where you’ll need a Plastic Shovel.

Once you’ve collected every bottle and completed every dig site, you can place them into the pillars near the gate to unlock the Heart of the Island.
