Sing for the Unicorn

T1, E5: You'd think a King would be safe standing on top of his own castle. But not when Ganon has managed to capture a flying Unicorn! Swooping down from the sky, the evil Underworld wizard makes off with the King to hold him for ransom. Price: one Triforce! Link and Zelda must descend into the Underworld to go to the King's rescue -- and there they meet an unexpected ally: a beautiful girl named Sing, whose Unicorn Ganon had stolen!
