Run through the pirates while taking damage or by using Plasma Beam. It is possible to get through the lower three pirates with a single hit while using i-frames to prevent a second hit. Either wait above until the pirates are a bit closer together and then run through, or arm-pump or horizontal damage boost to get through them fast enough.
