Stun the bottom pirate with a Power Beam shot, or i-frame past it. Farm the four pirates above for drops, then get back through the bottom pirate. Stun it with a Power Beam shot or i-frame past it a second time. Perform a 1-screen shortcharge between the bottom doors, then hop back up to the bottom pirate's ledge and get shot at.
