Golden Monster

Golden Monsters is the blanket term for the many golden enemies that appear in Oracle of Seasons and The Minish Cap, usually triggered by the activation of an event, or Kinstone Fusion, as in The Minish Cap. These enemies are much more stringent versions of the common Octoroks, Ropes, Moblins, and Tektites, just to name a few. While these incarnations are much stronger, and much more prized by the community, the Golden Monsters in The Minish Cap also see an increase in speed over their lesser, basic variations.

Oracle of Seasons
After Link talks to a certain old man near Eyeglass Lake in Oracle of Seasons, four different Golden Monsters will appear around various regions of Holodrum. When all four have been defeated, return to the old man to receive a Magic Ring which, when appraised, becomes the mighty Red Ring.
 * The Golden Darknut can be found on Western Coast during the Spring.
 * A Golden Lynel appears in Tarm Ruins in Winter.
 * The Golden Moblin hides in the Woods of Winter, but only during Autumn.
 * A Golden Octorok waits to be defeated around Spool Swamp in Summer.

The Minish Cap
In The Minish Cap's Hyrule, three types of Golden Monsters appear after certain Kinstone Fusions. They are Octoroks, Tektites, and Ropes. They are much faster, can take more damage, and dish out more damage, but their basic attack pattern remains the same. After one is defeated, a chest will appear nearby.
 * Golden Octoroks will appear in the Minish Woods, Wind Ruins, and Western Wood.
 * Golden Ropes are found in Hyrule Castle Garden, Eastern Hills, and Castor Wilds.
 * Golden Tektites appear in Mount Crenel and Veil Falls.
