Double Spring Ball jump while artificially morphed and quickly unmorph and freeze the fish before landing on it. The required positioning of the fish is fairly precise; aim for it to be at the lowest point a few tiles from the right wall, or one tile from the right wall where Samus has more time to press against it. Down grabbing onto the fish makes this significantly easier. The fish should be frozen in one hit, this requires Plasma and Wave or a single Power Bomb hit and Plasma or Wave and Spazer. With Plasma, it is tricky to freeze the fish without killing it; avoid shooting it horizontally. The positioning of a Power Bomb, is fairly lenient, but will always hit the fish once if placed a couple tiles below the peak of a normal Spring Ball + HiJump.
