The Legend of Zelda: The Minish Cap/Golden Monsters

Golden monsters are special, stronger versions of some monsters. Sometimes when you fuse kinstones with someone, a golden monster will appear somewhere in Hyrule. The golden monster's location depends on where its symbol is on your map. When defeated, golden monsters leave behind either a giant green or giant red rupee. The three types are golden octorok, golden tektite, and golden rope.

Octorok
The golden octorok will shoot rocks more aggressively than normal octoroks.

Tektite
The golden tektite will jump around much faster than normal tektites.

Rope
The golden rope is much more aggressive than normal ropes.
