Either jump over a Cacatac or tank a spike hit. Perform a mid-air spark through the speed blocks. Then run to the right and back to get speed to go through the rest. If performing the spark with low energy, there is a risk of ending the spark above the spikes or in front of the Pirate; to be safe, assuming Samus has heat protection, begin the shinespark with between 73 and 88 energy, or at least 106 energy; with a buffered crumble jump to the right, up to 94 energy can work.
