• Year: Any

• Day: The day after a storm
• Time: Anytime
• Location: Mineral Beach

Go fishing at Mineral Beach the day before a storm and keep fishing until you catch a bottle.

The next day (after the storm), talk to Kai and give him the bottle. He’ll ask you if you plan to stay in the village or leave someday.

Choose the option that says you plan to stay, and he will fill the bottle with perfume and give it back to you.
