Underground cavern

The underground cavernMetroid: Other M Premiere Edition, page 63: "Roll into the hole and you'll drop several feet into an underground cavern. Clear a path out of the cavern, past vine coverings, Reos, and Grippers, until you reach a sealed hatch. Defeat the Griptian guarding it quickly with a missile and a Lethal Strike, then pass through the hatch when it unlocks." is a room in Sector 1 / Biosphere. It appears in Metroid: Other M.
==Description==
This is a rather unremarkable corridor carved out of a dirt tunnel, although small green or blue ferns can be seen growing from the soil in the walls and floor. At different points of the cavern are stretched roots for Samus to jump or vault over, similar to other natural and manmade barriers in corridors across the BOTTLE SHIP. Unlike other areas of the BOTTLE SHIP, such as the adjacent jungle environment, this room does not appear to be simulated.
Light emanates from the hole in the ceiling that Samus drops through into this room. It is not possible to climb back up the hole, forcing Samus to return to the front of the Biosphere via an intersection a few rooms away.
Lining the corridor are walls of Kihunter webbing that have trapped Reos. Samus can destroy the webs in Search View with her Missiles, which releases the enemies for her to kill. She also encounters Grippers in this room. On the exit door is another web that is shaped like a cocoon; shooting it reveals a Griptian. The door out remains locked until Samus dispatches it, at which point she can access the Biological Experiment Floor. The webbing most likely originated from the Kihunters in that room, where their nest is found.
After the credits, this room is empty, but a trip through here is necessary if playing for 100% completion, unless the alternate route from the intersection is taken.
