Roll all the way right before using Xray to stand up, aligned with the right side tiles. Partially clip into the floor to enable the next jump. Use an R-Jump to morph into the tunnel. The second morph ball sized hole can be passed by simply jumping out of the floor clip position with diagonal held.

Dev note: The item is inside of a Chozo Ball, so there is no way to use artificial morph on the return.

It may be necessary to turn off Gravity Suit in order have more time to jump and morph underwater.

Space jump while partially submerged for more time to mid-air morph.

Wall jump until Samus is just below the water line and then morph and place a Bomb Use the brief moment during the Bomb explosion that knocks Samus upwards to setup a Springball jump to jump out of the water.

Requires:

"canSunkenTileWideWallClimb",
"canUnderwaterBombIntoSpringBallJump",
"canWallJumpInstantMorph"

Dev note: FIXME: This can also be done with a double Spring Ball jump (using Bombs) without wall jumping, but it seems more difficult than Statues Room and West Cac Alley, because of the water tide.

Perform a canSunkenTileWideWallClimb to get to the water surface, then use space jump at the water surface. Then either use space jump when the water is low then a spring ball jump to escape, or space jump when the water is high into a tight midair morph.

Requires:

{"notable": "Escape - Suitless, Bootless, Space Jump"},
"canSpringBallJumpMidAir",
"canSunkenTileWideWallClimb",
"canTrickyJump",
"can4HighMidAirMorph",
"canSpaceJumpWaterBounce"

Dev note: The canSpringBallJumpMidAir is for the bottom left part of the room. The can4HighMidAirMorph is to represent the quick morph during the escape.
