Your island will at last have discretionary NPCs, like Animal Crossing Items for Sale Gulliver or Saharah, who make an outing for some clarification.
You'll have to meander around to see whoever might be stopping in your town. Some of them for the most part appear in tantamount spots. Gulliver, for example, will be finished by the sea side, and a merchant like Label will be in the town square.
Any spot you track down them, chat with them and see lolga.com what they need — without a doubt they're selling, which can be prohibitive things.
