Meg

This is the fourth Poe that Link encounters in the Forest Temple and is the hardest one to beat, because you can't touch it with your sword. Meg begins the battle by turning into four exact duplicates and surrounding you. At this point, the real Meg will spin around. This leaves Link a short period of time left until Meg attacks, before which she will spin around once more so target the real poe with your arrow or hookshot and shoot her. If you shoot the wrong Meg, it will disappear. Perform this attack three more times and she will perish and give access to the basement floor.

Amy made a cameo appearance at Ikana Canyon where you can battle all four of the poe sisters to earn a Piece of Heart in a small hut for 30 rupees.
