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 recieved the bow within the Forest Temple, Link must seek out the Poe Sisters, whom guard the entrance to the temple's basement, where the boss, Phantom Ganon awaits. Joelle's room consists of a single, empty room and a three-level staircase, upon which three identical pictures of her are hung, one on each level. Shoot each picture of her with the arrow individually, the pictures will go up in flames and her likeness will disappear from the wall. When the third picture is burnt, Jo will reveal herself and appear at the bottom of the stairs, awaiting Link. If you target 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, she will puff up in 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 function 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 nearby for 30 Rupees. Here, Tatl identifies Jo as the second of the Poe sisters, however, it is inferred that she is also the second oldest of the four, under Meg.
