Spark left 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 and begins sparking about 3 tiles from the Speed blocks, start with between 72 and 87 energy or at least 105 energy; with a buffered crumble jump to the right, up to 93 energy can work.
