If Supers are available, Samus can knock the crab off the ceiling and freeze it mid-air, using it as a platform to jump onto the frozen fish above. Alternatively, use one of several possible methods that do not require Supers: 1) Freeze the crab on the corner of the ledge and the fish near the wall but with enough space for Samus to fit through and jump up. 2) Freeze the crab on the ground and the fish low, then crouch jump and down grab onto the fish while pressing into it to gain extra height. 3) Freeze the fish near the left wall and wall jump into it repeatedly.
