How do I defeat Phantom Shadow beast Bongo Bongo?
First of all you have to shoot his hands using the Fairy bow or Longshot. You’ll know when you’ve got him because they will turn blue and he’ll shake them in pain. After freezing both of his hands, you must target the main body. Use the Lens of truth to uncover the target area. Shoot the round eye like portion of his body and Bongo Bongo will fall to the ground, stunned. Run up to him and attack with your sword.
