Build up run speed and then use controlled springball bounces to cross the ocean to the far right ledge, and then use SpaceJump to reach the door. Mockball down the submerged ramp and begin SpringBall bouncing under water using the platforms. Disable SpringBall after the final jump once Samus starts falling again as a way to gain extra speed.

Enter the room while building a shinespark and use it on the lowest part of the ramp to cross the room and reach a raised ledge on the right side wall. From there, use SpaceJump to escape the water. Carry the shinespark to the bottom of the ramp by delaying the first Choot with two Power Beam shots, killing it, or bounceballing through it. The Choot can be shot diagonally from the middle platform, and again by running off that platform and aiming down to float above it.

Notable: true

Standing from the rightmost platform, jump to the right of the stalagmite. Perform a midair wiggle to get to the left to the stalagmite, then precisely wall jump off of it. Then perform a frame perfect space jump at the water line to bounce on the water over to the Kamer platform.

Get to the right of the Choot on the rightmost platform. Spin jump up to the right, break spin while aligned with the wall, then freeze the Choot and stand on it while it is midair to the right of the stalagmite. Jump from the Choot to the water line and space jump at the water line to the Kamer platform.

Notable: true

Freeze the right-most ramp Choot in a way where Samus can climb on top of it and use Space Jump to escape the water. Use a turn around to avoid knockback when making contact with the Choot to better time the use of Ice. Freeze the Choot as far to the right (on its lowest swoop), but this method is less precise than the alternatives. If Samus is inside the Choot when it is frozen, she can continuing moving freely. Jump on top either in spinjump or in Morph Ball Use XRay to standup, clipping partially into the above slope. Use a flately jump to fall out of the wall while still keeping enough height to spacejump on top of the water and escape.

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.
