Once a Monster reaches level 15 on one of the Natural Islands (Plant, Cold, Air, Water, Earth), select the Monster and press the "Place" button. Choose Gold Island from the available options.

Gold Island is special and Monsters placed on Gold Island also remain on their Natural Island! Travel back to Gold Island to hear your Monster play their new Gold Island song.

If a Monster is removed from its Natural Island, its copy will also be removed from Gold Island.
