It’s to go fishing🎣
You may notice the Boat near the shores of your island.

Welcome aboard! Pick the character, provide them with food for the labor and the Fishnet, and wait til they come home with the catch.

You have the chance of getting Fish, Shrimp, and Salt. It will be very useful for future recipes.
Upgrade the Fishboat and get Shrimps and Salt guaranteed!

Bon voyage⛵
