You can crystal flash for early setup, then bounce between thorns and Kraid to setup. Alternatively, force Kraid to stand up and farm his nails for energy. Then perform a Spike X-Mode on the thorns to get shinecharge. Get interrupted by Kraid for blue suit. After gaining blue suit you can proceed to defeat Kraid.
