The Fungal Hall B is a room in the Phazon Mines, in the game Metroid Prime. It is composed of very large Saturnines and a floor full of Phazon. There are several Metroids in this room, as well as a Glider, which Samus must grapple on to in order to progress. Because this place is very dark, the Thermal Visor can improve vision. This room connects to a Missile Station.
