Seriously, F--- this level, it's harder than any of the bosses in the game.

Git gud.

More seriously, what's the part you're having trouble with? I'm assuming the octopus part? The projectiles can get quite overwhelming, the trick is to stay in one place until all three shrimps are launched then move on the part that won't get one.
Still have to look out for the clam, though, so it's not perfect, but if you manage to get there with 3HP (not that hard if you take it slowly and use the smoke grenade), you should survive.

What weapon is recommended for the octopus? I keep getting 99% of the way, it's so crazy how I get jammed up at the very end every time.

Well, the recommended weapon is nothing. Always try to beat run and guns as pacifist mode, it's really not any harder than beating it normally. Just take smoke bomb with you and GG. Best rank you can attain too. The reason it isn't harder because you won't at all be focusing any of your attention on killing anything you will just be dodging it all. You will notice even on the octopus how simple the enemy pattern is. The bubble shot always comes at the exact same time. Once at the height of the enemies jump, then as he's falling, the jumping fish things always come at you in the same repeating pattern too. It's super easy to just jump around them. Or use parry to save yourself when needed off of the octopus.

As Codester said, nothing is the best weapon in run and gun levels. If you want a weapon and if the shrimps are killable (I don't even know since I never use weapons in run and gun stages), I'm guessing spread (aimed up) or chaser could be good?
