Biological Experiment Floor

The Biological Experiment Floor is a room in Biosphere in Metroid: Other M. It bears resemblance to an earlier explored shaft in the area, with a long, curving platform leading to the top of a pillar. Several strange plants resembling Sporbs are attached to the wall and try to hit Samus with tentacles. As Samus reaches the top, she will find a hole leading into a chamber at the base of the structure. Here, she will encounter several Zoro and be attacked by numerous spawning Keyhunters. She must destroy several support structures for the main structure in the room, which will then cause it to crack. More Keyhunters will ambush, and Samus will see a strange silver bioform in the remains of the structure, which could possibly be their queen. She must fire Missiles at it to agitate it and cause more Keyhunters to ambush. When defeated, it hardens into stone. Samus then notices ULF 55 feeding on what looks to be honey. She leaves as Adam gives her her next instructions.
