Bounce on the Power Bomb, then quickly kill the remaining Sidehopper with a strong beam, ammo, or pseudo-screw. If Samus has a weak beam, use the bomb to boost to the right to get the Sidehopper to jump to the right, then morph under it while killing it.

Traverse the room with a small number of Power Bombs. If the Chozo item is still there, it is best to exit G-Mode before the final Power Bomb goes off to ensure that PLMs aren't overloaded. This strat can be done easily with 7 Power Bombs. Simply kill all of the Boyons before progressing. The final Power Bomb needs to be placed on the second to last floating platform or later to break the wall. Samus can use one Power Bomb and a Boyon hit to get from the door to the second platform, or from the second to fourth platform. Alternatively, when next to the Boyons, place a Power Bomb while the Boyon is low, slightly after the peak of the jump, hitbox through the Boyons. If the Boyons are killed, Samus can horizontally boost far enough to skip a platform. Samus can cross the room with any of the following: 7 PB; 6 PB and a horizontal boost; 5 PB and hitboxing the first Boyons; 5 PB and damage from the first Boyons; 4 PB and damage from the first Boyons and hitboxing the second; 3 PB and hitting both sets of Boyons. Note that if Samus falls into a Samus Eater, she will often be teleported into it when exiting G-Mode.

Run with enough speed to jump (after the transition) to reach the far left ledge. Either kill or Kago through the Fish enemy. At slightly higher run speeds, Samus can jump from the bottom of the slope and avoid the fish.

Safely kill the first pirate, then walk through the rest while taking damage or by using Plasma Beam. It is possible to get through the lower three pirates with a single hit while using i-frames to prevent a second hit. Either go below the pirates and use the camera to manipulate them to be closer together, or arm-pump or horizontal damage boost to get through them fast enough.

Run through the pirates while taking damage or by using Plasma Beam. It is possible to get through the lower three pirates with a single hit while using i-frames to prevent a second hit.

Climbing the shaft with Space Jump is slower than other methods, so it is necessary to move quickly in order to minimize acid damage. With each Space Jump, release jump early rather than doing a full-height jump, in order to be able to Space Jump again more quickly. After reaching the top, fall down on the right side to land on the platform above the door. Then press against the left wall and pass through the last Pirate while firing a Plasma shot down to open the door; with precise timing, damage from the Pirate can be avoided by hitboxing through it. Hold left to land directly in the doorway. If done quickly enough, it is possible to avoid any acid damage.
