Joelle

Joelle, or Jo as she is referenced in Majora's Mask, is the one of the four Poe Sisters that Link will meet in the Forest Temple in Ocarina of Time, and likewise in Majora's Mask, in the Ikana Canyon region.

Ocarina of Time
After Link has received the bow within the Forest Temple, Link must seek out the Poe Sisters who guard the entrance to the temple's basement, where the boss, Phantom Ganon, awaits. Joelle's room consists of nothing but a three-level staircase and three picture frames on each level, one of which will contain a picture of her and two of which will have black canvases. When Link approaches the picture of her she will cackle and disappear into another picture frame. If Link shoots a picture of her with an arrow, the picture will go up in flames and her likeness will disappear into another frame. When the third picture is burnt, Jo will reveal herself and appear at the bottom of the stairs, awaiting Link. If Link targets the poe, she will disappear and reappear, spinning towards Link, flaming torch in hand. Although a rudimentary sword/shield approach never fails, the easiest and most life-conscious way to defeat this Poe Sister is to snipe her from afar with the bow. After five hits from the bow (or two jump-attacks with the Master Sword), she will disappear in a puff of smoke, and a red-flamed torch in the main room of the temple will ignite.

Majora's Mask
Jo makes a cameo appearance at Ikana Canyon in Majora's Mask as a participant of a small in-game event; Link can battle all four of the Poe Sisters to earn a Piece of Heart in the Spirit House for 30 Rupees. Here, Tatl identifies Jo as the second of the Poe sisters.

Trivia
Jo resembles the Shadow Hag from Oracle of Ages.
