Perform multiple stationary lateral mid-air morphs, while avoiding the Evir projectiles, to cross the room. It is necessary to start the jumps from the far side of the platforms in order to gain more horizontal momentum before entering the sand falls. Falling into the sand will often result in a soft lock.

The first Spring Ball jump is performed farther away from the sand tile so Samus can build up momentum and height before entering the sand fall. The second jump must be made from the right half of the solid tile (but not the rightmost pixels.) The third jump will land on the sand and must be followed by a jump off of the sand. Falling into the sand will often result in a soft lock. Only the far left section of sand, near the door, can be escaped with a crouch jump.

Glitch through the Mother Brain Zebetites by using a frozen Rinka and i-frames. Freeze the Rinka at its spawn location, then spin jump or down-back onto it after acquiring i-frames to clip inside of the Zebetite, then jump through. I-frames can be acquired from a Rinka hit, a turret shot, or from the Zebetite itself. Note that Zebetites cause i-frames but deal no damage. If Screw Attack is equipped, then a down-back must be used, since spin jumping will cancel i-frames. With Ice+Wave, Samus can freeze the Rinka from above with an angle-down shot; Otherwise Samus must go below, press against the wall, and freeze it with an upward shot. With Ice+Plasma, Samus must be crouched when firing the shot.
