This is a rather unremarkable corridor carved out of a dirt tunnel, although small green or blue ferns can be seen growing. At different points of the cavern are stretched roots for Samus to jump or vault over. 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.
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.
After the credits, this room is empty, but a trip through here is necessary if playing for 100% completion.
- ^ Metroid: 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."
