I used the elevator to descend to the bottom. It's an Eerie Cave!

There are two more doors at the bottom, so I'll see what's in the left one.

The Eerie Cave (不気味な洞?)[1] is the first room visited in Ridley's Lair in Metroid and Metroid: Zero Mission.

In Super Metroid, the lava room fills the same role as the Eerie Cave.


The Eerie Cave is the location of an Elevator connecting to upper Norfair. This makes the Eerie Cave the main entrance and exit of Ridley's Lair during Samus Aran's Zero Mission, and is therefore the room where the Ridley's Chamber theme is played for the first time.

The Eerie Cave is completely devoid of any living inhabitants. It features fuchsia and silver architecture seen commonly throughout much of Ridley's Lair. A pool of lava is present in the room, but is completely inaccessible as it is under the floor. A large block is positioned above the floor, and aids in getting up to the elevator.

As with all Elevator rooms in Norfair, the redesigned Eerie Cave in Zero Mission features decorative statues. The Elevator platform features a pair of miniature Chozo Statues, and ridged poles are topped with Koma faces. Compared to the Koma in Norfair, these Koma have a slight purple tint and blue eyes. The block at the bottom of the room has been replaced by three small pillars composed of Fake Blocks.

During a normal playthrough of Zero Mission, Samus must first enter the Eerie Cave after freeing the Kiru Giru from the Tangle Vines in Norfair, but finds herself unable to progress much further in Ridley's Lair. Therefore, she must return to Norfair above and reenter Ridley's Lair through Imago's hideout. However, the Imago boss fight can be skipped with Sequence Breaking, making the Eerie Cave the only required entrance to Ridley's Lair.
