Dark ChuChus are the last variant of ChuChu Link encounters (assuming, of course, that he has found at least one Blue ChuChu). They are invulnerable to all Link's weapons, except the Mirror Shield. The only way to defeat them is to shine light on them, turning them into stone. Then, Link can either throw them, which destroys them, or just simply smash them with the Skull Hammer. They can also be dropped on switches in order to solve certain puzzles. They are found in the Earth Temple, the Savage Labyrinth, and Ganon's Tower.
