The field is divided into three platforms, each separated by nothing but a grappling point and poisonous water. The Chykka Adult has a projectile attack that easily blasts you off the platform and into the deadly water. The Chykka Adult must first be stunned by shooting it up front. Then, you must grapple onto a platform behind the Chykka Adult and shoot its wings (preferably with Super Missiles to just hit each point one by one). This can prove to be very difficult if you have not mastered the Grappling Beam. The Chykka Adult will not stay stunned for long -- be quick about it. After destroying all four weak points on the back of its wings, the creature will fall into the water and mutate into the Dark Chykka Adult. The only thing you can do to this creature is shoot its pouch. Take out the Light Beam and blast away. Charged Light Beam shots work the best. It may sometimes launch a group of small creatures at you (mainly to kill and get some refills). After defeating the Dark Chykka Adult, it will revert back to the normal Chykka Adult again. You must repeat the same process again; stun the creature, grapple behind it, and blast the back of its wings with missiles. It may sometimes try to run into you, but usually fails. Then when it turns into the Dark Chykka Adult, use the same strategy and hit its pouch with charged Light Beam shots. This battle could take a while, so be prepared. For all your efforts, you are awarded the Dark Visor.
