Long pathway

The long pathway is a corridor in Sector 1 / Biosphere. It appears in Metroid: Other M.

Description
Samus comes to this room after she encounters a small, furry white creature that stares at her intensely. The door to it is initially locked, but Adam unlocks it for her and instructs her to proceed.

The hallway is lush with jungle foliage including trees, ferns and stretched roots, which Samus jumps or vaults over. Further along in the room is a pair of Fly Pods attached to the walls that will continuously spawn Reos until they are destroyed. Once the enemies are cleared out, tiny glowing insects called Zuru will slowly pour out of a hole in the wall (erroneously referred to as a portal in the Prima Games guide). These act as a subtle hint, and stop emerging when Samus enters the hole, into a tunnel in Morph Ball mode. This leads to a holographic generator on a high ledge. When used, the generator will disable an invisible wall and reveal the exit door.

This room is witnessed in TV Commercial :60 Spot, the game's live-action commercial. Samus is seen in gameplay SenseMoving away from the Reos twice and quickly targeting one in Search View.

Connecting rooms
The room connects to the large forest room where Samus first encounters Little Birdie, after its screams agitate the local wildlife. It leads into a straight, industrial corridor filled with Geemers and red floor lights, with significant damage to the walls and a sensor locking the door to the Observation Room.
