It's fish. They're talking about the fish that live near each island.

You know how you can buy bait from those guys in the boats... Buy a lot, and when you see a fish jumping out of the water, sprinkle some bait above it... Not only will they draw on your map, the island that they're near, but they will also give you information... You will get info about two islands you have to go to... Ine of them is the really windy island, and the other has something else happening at it... But you'll need special items to help you get inside the islands... I suggest you look in the walkthroughs section if this website, for this specific game, I used one for the same game, that was magnificent!

If you have the Ballad of Gales, play it, Teleport to Mother & Child Isles and you'll get the Fire and Ice Arrows. Now go to Fire Mountain, use the Ice Arrows to freeze the lava coming from the Volcano, enter it and get the Power Bracelets - next, go to Ice Ring Isle and inside it you'll earn the Iron Boots. Following that, you need to go to Headstone Island, use your Power Bracelets to lift and throw the huge rock - inside you'll learn the Earth God's Lyric for the Earth Temple. You'll also need to go to Gale Isle, put on the Iron Boots to get inside and learn the Wind God's Aria for the Wind Temple. Lastly, go to Dragon Roost Island, find Medli at the top of the Island, play her the Earth God's Lyric and take her to the Earth Temple on Headstone Island. When you beat the Temple, go to Forest Haven, find Makar under the Waterfall, play him the Wind God's Aria and take him to the Wind Temple on Gale Isle.
