After you stand on the floating statue head (to get the Mallet), push the old fisherman to the right, past the Bell Gong, to near the first barrel. Then when you use the mallet to hit the gong, the fish will jump onto his line.
push the box that he's sitting on to where the fish jumps.
First, you move the fisherman. Then, you go in the water, jump on the dragon's head, get the mallet and ring the bell. The man will catch the fish and the map will be in it's mouth.
At Dragon Cove island, the old man will help you get the Map Piece. Climb onto the floating statue and you will reveal a Mallet. Push the old man to the right, past the giant Bell Gong to around the first barrel. Then strike the Bell Gong with the mallet. This will scare the fish from the water and he will catch one, and the Map Piece is in its mouth.
you get the stick but then move the old guy to the left he'll catch a fish then he gives you it because he finds it in the fish's mouth
Any type of fish that they could catch at sea or in their rivers and lakes.
Jump into the water and onto the floating statue head, and it will reveal the Mallet. Shove the old man to the right until he is near the first barrel. Use the mallet to hit the large gong and a fish will jump from the water onto his hook. He gives you the paper from its mouth, which is the Treasure map Piece.
You can catch fish that you couldn't catch on at the beach. Other than that the island is kinda useless and a waste of money.
Swim out from the left and stand on the sunken statue. The other end will come up, revealing a Mallet. Push the old man to the right, next to the first barrel. Use the mallet to strike the giant gong and fish will jump from the water. The one the old man catches has the map piece in its mouth.
The larger fish at Dragon Cove is the one you want the old man to catch. Stand on the statue in the water and its tail will come up revealing the Mallet. Push the old fisherman to the right, past the giant gong, to near the first barrel. When you use the mallet on the gong, the fish will jump onto his line, and in its mouth is the map piece.
You need the mallet, and the old man has to be in the right place to catch the fish. To get the mallet, stand on the floating statue. The other end will pop up with the gong. Push the old man to the right, to near the barrels on the right side. Use the mallet, and the fish will jump to his line. The map piece is in its mouth.
First you go push the guy sitting on the box, near the beginning (right side) of the stairs. Then you go in front of the big bell and click "use" for the mallet. Then the fish will jump/swim up and the guy will catch one of the fishes, which one of the fish has something in its mouth, which you will be able to keep it as a reward.
The fish you catch is all random. They have certain fish in certain places but I caught the yellowtail quite a lot at crystal island in the tidal pools.
