The Flame Lantern is an item in The Minish Cap.
The Minish Cap
The Flame Lantern is found in the fourth dungeon, the Temple of Droplets. While Link is in the Temple of Droplets, he can use it to melt hunks of ice. It also allows Link to see in darkness. Link can also use it to light torches to light up rooms and to solve puzzles. The Lantern is necessary to defeat the corresponding temple's boss by igniting the plant-like portion of the creature's body. It is also used against Gibdos to light their paper up, turning them into a Blue Stalfos.
