Niboshi

The Fish Saleswoman is a character in Spirit Tracks. As her name suggests, she sells fresh fish in Papuchia Village.

After Link completes the Fire Temple, he can talk to the Fish Saleswoman, who will mention that she is in need of Mega Ice in order to keep her fish stock fresh. The young hero must purchase Mega Ice from the Anouki in Wellspring Station and take it back to the saleswoman. If he brings her at least 10 units of Mega Ice, she will reward the young hero with a Force Gem that reveals more Spirit Tracks in the Ocean Realm, opening the way to the Pirate Hideout north of the village.

Link can buy 20 fish for just 50 Rupees. If the young hero manages to bring at least 15 fish to a woman in Hyrule Castle Town, he will receive another Force Gem that recovers more Spirit Tracks in the Ocean Realm. It is not necessary to bring Mega Ice to the woman in order to buy fish; in fact, the woman will not accept the ice until after the Fire Temple has been completed, but she will sell Link fish as soon as he has the Freight Car.
