Wing Dungeon is the second dungeon in The Legend of Zelda: Oracle of Ages. It is found in the Deku Forest, the forest known as the Fairies' Woods in the present. The main treasure is the Roc's Feather, and the boss is Head Thwomp. Wing Dungeon is viewable in both the past and the present, but can only be entered in the past. Link accidentally causes the dungeon to collapse when he goes near it in the present, which is due to the fact that the dungeon is an old and frail structure.
The first floor of the Wing Dungeon is shaped like a bird. It has green floors, yellow doors, blue blocks, and grey walls. An Owl Statue can be found in the first room. In all, three Mine Carts, as well as track sets, are found within the dungeon. It contains three side-scrolling areas; the first one contains a Thwomp, many ladders, and some moving platforms; the second contains the Roc's Feather and a blue Rupee; the third one contains the boss, Head Thwomp. As with many dungeons in the game, it features many puzzles that focus on color.
