The Dungeon contains a large pool of Dark Water that covers a submerged maze. There are two Dark Grenchlers that patrol the area. Beneath the water, there are two Watchdrones that can only be moved by activating nearby Light Beacons. After Samus navigates the waters, she can equip the Dark Visor to find and destory a Flying Ing Cache to obtain G-Sch's Sky Temple Key.
