Beth (Poe)

Beth (ベス, Besu) is the second Poe Sister that Link will meet in the Forest Temple in Ocarina of Time. Like Joelle, she will need all three pictures to be shot with the bow which will then bring the Poe out from hiding. She will appear in the bottom of the room and there she will be swinging her torch at Link. To defeat her, block her attacks and hit her with the sword five times. Upon defeat, she will disintegrate and the blue torch will be lit.

Majora's Mask
Beth made a cameo appearance at Ikana Canyon in Majora's Mask where you can battle all four of the Poe Sisters to earn a Piece of Heart in a small hut for 30 rupees. Tatl identifies Beth as the second youngest of the Poe sisters.
