Description[edit | edit source]
As the name implies, the blue-bubble shaft is a lengthy vertical shaft composed of bluish-purple bubble-blocks in Metroid. In Metroid: Zero Mission, the surfaces of the walls, floors, and ceilings are covered with natural green rock, although the blue bubble-like material is still visible beneath them.
The blue-bubble shaft is perhaps one of the most important rooms in Norfair. It runs vertically up and down the entire length of the area along its right side, thereby directly connecting all significant portions of Norfair: the Ice Beam's location in the upper-right section, the elevator to Brinstar in the middle, the various upgrades in the lower half, and the elevator to Ridley's Lair at the very bottom. Therefore, it is necessary to reach the bottom of the blue-bubble shaft in order to access Ridley's Lair.
However, the blue-bubble shaft's full size is not immediately obvious. When Samus Aran first enters the shaft, it initially appears to be a much smaller room. She must break through several ceilings and floors of the shaft's multiple chambers by using various tools at her disposal. In Metroid, she can simply use her beams and bombs. In Zero Mission, much of the process of navigating Norfair revolves around puzzles using the Speed Booster to break away Boost Block portions of the floor; this must be done by building up speed in adjacent corridors. To quickly ascend the shaft, Samus can use a well-placed Shinespark, a Morph Ball launcher, and/or the Screw Attack.
Furthermore, the blue-bubble shaft provides one of the biggest Sequence Breaking tricks in Zero Mission. The very top of the shaft, inhabited by a single Ripper and Sova (which can be frozen with the Ice Beam and used as a platform over the Pit Blocks), has a Missile Block that hides an unmapped portion of the shaft, which also runs up and down the entirety of Norfair's right side. This hidden passage completely bypasses the Boost Block puzzles and the first two Kiru Giru larvae, allowing Samus to fight the ensnared Kiru Giru and enter Ridley's Lair without the Speed Booster or Wave Beam. Another Missile Block covers the exit at the bottom of the blue-bubble shaft; to ensure that Samus has at least enough Missile Ammo to break it, a Gamet nest can be found in the shortcut.

- "The shaft on Norfair's far right side is formed from natural green rock. Climb up to the first hatch on the left and continue your journey to the next upgrade."
- 058 ADVANCED SHORTCUT (p. 41)
- "A narrow, winding path leads through a hidden shaft on Norfair's right edge. If you're confident that you can defeat Ridley without collecting some key items, freeze the flier in the upper-right corner, hop onto it, then use a missile to blast into the shortcut. Be warned: the shortcut requires expert bomb-jumping skills."
