In the Chozo ruins you will come to a machine that is pretty much an automatic flame thrower. To defeat it first you dodge its flames. Then the top part will come out with a red circle. Keep shooting that until the machine burns the bee hive. Then a bunch a bees will come out and try to attack you. Kill all of them and dodge the flames. (Make sure you scan the wasps in this fighting cause its a defferent kind). Keep repeating this process about 3 times. Then it should explode and you will get the morph-ball bomb.
