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.

Get to the bomb blocks while morphed, use a Power Bomb, then exit G-mode and drop to the bottom of the room. It is possible to go through the top pirate while it is being hit by a Power Bomb explosion, otherwise it is possible to jump over it with Morph or Spring Ball. With Bombs, it is possible but tricky to IBJ over the pirate or Bomb it many times to kill it without it placing any of its stationary, invisible lasers. Note that the pirate will not turn towards Samus and place a laser if it is moving its head back and forth.

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.
