Overload PLMs by placing Bombs at the far right, against the bottom of the crumble block, at the right of the low underwater ceiling. With artificial morph, safely bomb the fast crab by waiting just left of where it falls. Lure a crab to the top door or wait for the global crab to come back around, which can take up to 2.5 minutes. Shoot a Super to knock the crab off, then quickly freeze it at the right height and use it to clip up past the door shell. Knock it off while it is on the sloped tiles near the top door, not on the door itself, otherwise it will never be in the correct height. Because of the shot firing rate, it can help to crouch and shoot the Super to the side to give it a bit more time to knock the crab off.
