Legend of Zelda: Ocarina of Time Special Edition, The Cheats :
Secret - Sinking Lure
If you want to easily catch really big fish in the fishing pond without having to spend countless hours, then make sure you have caught the "lunker" fish as an adult and have obtained the gold scale. Now go to the fishing pond and you will find a new lure in one of three places: 1.) in the feeder creek, 2.) in the grass around the perimeter of the area, or 3.) on the log jutting out of the pond. Once you find this lure, try fishing with it. It is irresistible to fish, so catching a 20 pounder will be no problem. However, if you set any records by using this lure, the fish you have caught will be noted as illegal on the aquarium and at the record board in Link's house.
