Golden Scale

The Golden Scale is a gold scale encased in a green sphere of water that Link receives as the prize for catching a 20 pound (9 kg) fish at the Lake Hylia fishing pond. It allows Link to dive for up to 9 seconds and supersedes the Silver Scale.

Glitches
There is a glitch that allows the Golden Scale to be obtained in the period prior to Link's adulthood. After catching a fish worthy of the Heart Piece prize, Link must swim to the middle of the pond, and positioned to face the owner of the Fishing Pond. The player must then hold down on both the 'Z' button and either the 'R' or 'L' buttons on the controller for Link to pull out the Deku Shield and assume a defensive stance.

Subsequently, by swimming towards the owner and speaking to him without letting go of the buttons, the glitch will be activated, causing him to give the Golden Scale as the prize for the lunker.
