Stuck with two sector passes that seem impossible

How do you get these passes????? This is where you are given a tall box in which you cant jump to the first ledge, many layers of enemies above you, and a magbomb launcher and ammo below. You have about 30 seconds from crate spawn until wormhole spawn, it's just not enough time to do anything. I tried shooting bombs through all the floors to make it fall but I couldn't get it to work, not enough time. What in the world are you supposed to do. Both passes I need are this same garbage! I am stuck one item from lvl 14 forever. The Glockenspiel sector has one of these.

I only saw this container once. Maybe you have to get magbomb protection and then launch yourself into the air with the explosion. Also the sector, where the sectorpass was in this special container, had another special container the next playthrough. So I hope this helps you :)

Shoot up, blow up magbomb, repeat. Zoom out a bit to make sure you're blowing up all the platforms under the pass. I've cleared several of these kind of sector passes.'

Most dangerous part about this kind of sector pass container is that it can be hard to kill the enemies/prevent them from spawning depending on where the crystals spawn. You can take out two platform sections at once if you shoot a bomb at a midpoint, which can make it easier to force some crystals to fall.

Appreciate it. It's strange. I redid these two sectors and failed them repeatedly, then after the above poster said different ones would spawn in, I never saw these again. Bad luck I guess?
