Wing Dungeon

Wing Dungeon is the second dungeon of Oracle of Ages. Getting to it is challenging, since it collapses in the present time, so Link must travel to the past and uncover the entrance by blasting it open using bombs. The mini boss is Swoop, a stone bird-creature, and the item obtained is the Roc's Feather. Its dungeon boss is the Head Thwomp, an obvious take-off on Thwomps from the Mario series. Once Link succeeds in defeating Head Thwomp, he will receive another Essence of Time, the Ancient Wood, along with a Heart Container.
