Wait for the acid to lower then quickly roll part way forward to trigger the Metarees and return. Then go again without any difficulty. Killing any of the Gamets will prevent them from respawning. With Bombs, horizontally boost then IBJ above the acid while waiting for it. It is possible with Spring Ball alone, but it is easy to take damage; perform small jumps but hold jump before landing to prevent a small bounce in which Samus can't jump. On the return route, jump over the Gamets to let them pass instead of racing to get them off screen.
