This room serves as a corridor to fill in the gap between North and South Jungle Hall. Access to the rest of the room is blocked by wires, so Samus cannot navigate it in her bipedal form. Instead she must use a Morph Ball tunnel in the wall. Even then, it is blocked by a piston. Samus must pull it down with her Grapple Lasso. It will then lift her to a higher point in the wall, which will give her access to the second part of the hallway.
- Ship Missile Expansion
- At the end of the tunnel.
- "Piston is stuck in place. Enough physical stress could temporarily pull it down."
