He also had to fight a bunch of Darknuts and Moblins before he could get out. Out on the high seas, he fought Cyclos and learned the Ballad of Gales, which he can use to fast-travel around the Great Sea. He infiltrated the enemy sub at the Flight Control Platform and got the Platform Chart, which shows the locations of enemy platforms around the Great Sea. On the platforms at Seven-Star Isles, he found Treasure Chart #16, which let him salvage a Silver Rupee of the coast of Shark Island.
Now, Link will do the merchant trading sequence and then will help revive the withered forest trees. He could have done these sidequests earlier, but the Ballad of Gales makes them both faster.
Windfall Island:
Link resumes on Windfall Island. In town, he talks to Zunari at Zunari's reception counter. Mr. Z. has asked Link to help him establish a trade network with a few Traveling Merchants around the Great Sea. He indicates that there is merchant on Bomb Island, which is just north of the Forest Haven.
Currently, Zunari sells Town Flowers. Link needs to have at least one in his Delivery Bag for this quest.
Link returns to the King of Red Lions. He directs the Ballad of Gales to fast-travel to the Forest Haven.
Forest Haven (time 2:40):
Link sails north to the Bomb Island square.
Bomb Island (time 3:07):
On Bomb Island, Link finds a Traveling Merchant, who happens to be a Goron. He gives this merchant a Town Flower. In return, the merchant sells him a Sea Flower for 20 Rupees. This product will now be stocked in the Windfall Island shop.
If Link talks to this merchant again, he will tell Link about another Traveling Merchant on Greatfish Isle.
Link returns to the King of Red Lions and fast-travels to Greatfish Isle with the Ballad of Gales.
Greatfish Isle (time 7:09):
There is a Traveling Merchant on a raft between the two large western fragments of the isle. This merchant hopes for the fabled Shop Guru Statue. For now, Link gives this merchant the Sea Flower. In return, the merchant sells him an Exotic Flower for 25 Rupees. This product will now be stocked in the Windfall Island shop.
If Link talks to this merchant again, he will tell Lion about other Traveling Merchants on the Mother & Child Isles and on Bomb Island.
Afterwards, Link returns to the King of Red Lions. He uses the Ballad of Gales to fast-travel to the Forest Haven.
