Gain a specifc amount of speed by running from a standstill, starting slightly more than 3 tiles from the edge of the Ridley statue jaw. Jump on the last possible frame (second-to-last frame may also work, depending on subpixels). If successful, Samus will avoid bonking the wall and will land directly in front of the Namihe.

BounceBall into the Lava, Unmorphing with good timing to sink faster and drift effeciently towards the bottom right Namihe. Walljump at about eye height (4 pixel window) to gain enough height to reach the center portion of ceiling. While rising, wiggle to shrink Samus' hitbox. Some walljump positions will not need to wiggle, when walljumping far away from the Namihe. Jumping, from the wall, around the next lowest overhang is very precise and taking any extra time to position will increase the amount of lava damage being taken. It may help to disable HiJump for this part. Then Walljump again to exit the Lava and reach the left ledge.

Spin-jump across both sets of lava, trying to minimize the time spent in lava. To get onto the first pillar, either use a wall jump off the pillar, or use the Tripper briefly as a platform by crouch jumping or down grabbing onto it.

Requires:

}

Use the Tripper to cross the first lava pit while avoiding all damage from the spikes and lava. If you do not have Morph, this is tricky but can be done by carefully timing a jump against the pillar and releasing the d-pad inputs, to land on the Tripper as early as possible. This allows the Tripper to sink low enough that crouching on the Tripper is enough to avoid spike damage. From the Tripper, run and jump directly onto the first pillar past the shutter; it can help to moonwalk back left on the Tripper to maximize run speed for the jump. From the pillar, run and jump directly into the lava rather than waiting for the second Tripper. Perform quick spin jumps to minimize lava damage.

Wait for the Tripper to approach the right platform, then run onto and off its left side. Spin jump to the left one time, then jump up onto the right side of the Tripper.

Enter the room blue with very low run speed (e.g. with a 4-tap). Use a precisely timed jump to bonk the large stalagtite in the ceiling and fall through both pirates, killing them with the blue speed. Enter the acid while aiming down to shrink Samus' hitbox. This strat works with all combinations of movement items and suits.

Begin running from the top of the second slope and jump at the bottom of the third slope, bonking the large stalagtite in the ceiling. Kill the first pirate with Screw Attack (or ahead of time with Charge+Plasma), and pass through the second pirate using a charged plasma shot.
