Use the slow global crab and Skulteras to get up. The last part, just below the item is the hardest. Get onto the global crab on the right wall. Either freeze the Skultera close to the wall and wall jump between them. or, a harder option without wall jumps is to refreeze the crab again, higher on the wall, while being careful not to clip through it. Freeze the Skultera at the left, near its minimum and jump to it, then the solid ground. Note that the fish will be pushed down slightly over time because of the sloped tiles, but it will be at its minimum by the time the global crab has arrived.

Wait a long time for the slow global crab. Freeze it when it comes around on the left, one tile above the bottom slope. Freeze the fish, get on the frozen crab, and wall jump between the fish and the wall and the wall. Wall jump towards the fish to gain height faster.

Similar to naked Watering Hole escape. Freeze a crab under the gap above, do a stationary spinjump facing right, then walljump until you're up. Another frozen crab can help complete the way up.

Shinespark to the first ledge. To use a flash suit in deep sand: vertically - quickly roll the directional inputs from forward to up and jump. diagonally, with minimal horizontal speed - while holding angle, quickly tap forward then press and hold jump.

Requires:

"Morph"

While against the left wall, crouch jump and spark diagonally at the top of the jump. The easiest way to crouch jump without using the flash suit is to hold shot.

Use the Skultera to get onto the top right platform. There are two distinct ways to get up using the top Skultera. 1. Freeze it at the bottom of its path to the left. Crouch jump and down grab to get onto it. The positioning is very precise. 2. Freeze it about a half-tile from the right wall and very quickly stationary spin jump and quickly walljump mash to get up before it thaws. This may be easier by jumping away from the wall, towards the fish, to gain height faster.

Fall into the sand and roll all the way to the left, through an invisible tile and under the door platform. Shoot upwards to break part of the platform, then perform a crouch jump and down grab or a tile-wide wall jump climb to escape.
