Freeze the Choot when it swings right on its jump. Quickly get on top of it by first getting onto the pillar to the left, or with a SpringBall Jump. Perform a precise spring ball jump to get to the far right ledge, while avoiding hitting the water surface. While on the ledge, stand on the raised ground to the right and jump to the surface, then space jump across the water to the left.

The second jump is harder than a normal mid-air springball jump. Use either a stationary lateral mid air morph, to gain enough horizontal momentum, or a SpringFling to reduce Samus' fall speed as soon as it begins to build up. Shooting towards Pirates will cause them to stop in place and not fire back.

Jump towards the door with a Springball Jump, jumping as late as possible. A Flatley style jump can position Samus over the edge of the ledge, closer to the door, allowing for an earlier Springball jump. The slight fall from a Flatley Jump helps with the Springball jump, but then Samus must unmorph to extend her hitbox to touch the transition. A Stationary Lateral MidAir Morph also helps with this jump. Unmorphing after a missed jump can return Samus to the ledge to try again.

Be sure not to get the first downward moving crab on screen until Samus is in position to quickly and accurately shoot and freeze it. This is much tighter with spring ball relative to HiJump. Performing a max height spring ball jump from the frozen crab can get Samus to the next ledge. Getting to the ledge with the fish is particularly precise. Either stand at the very edge of the platform and perform a very precise max heigh spring ball jump, or stand against the left wall and and perform a slightly less tight stationary lateral morph into spring ball jump.

If HiJump or Spring Ball is available, use a Gravity jump from the top of the island; otherwise, use the higher ledge to the left, jump slightly early to avoid getting too much jump height (to avoid bonking the ceiling Grapple blocks), and quickly do a stationary lateral mid-air morph.

From the sand fall, quickly get onto the left platform to prevent the right side Evir from lowering too far. Jump on the sand to the right while freezing the Evir as high as possible. Refreeze the Evir so it is a slightly higher platform than the right pillar. Perform a spring ball jump with a stationary lateral mid-air morph from the left side of the current platform to get onto the Evir. Use a running jump off of the Evir. As a backup, it may be possible to make the Evir rise again by hitting it with a PB - place the PB in the air to avoid double hitting and killing it.
