The Wing Cap is an item found in Super Mario 64. It is Mario's signature power-up in Super Mario 64, being shown on the game's box art and a majority of its merchandise. When wearing a Wing Cap, Mario becomes Wing Mario and gains the ability to fly. Mario can begin flying by performing a Triple Jump or by getting shot from a cannon. The item can only be obtained from a red ! Block. While wearing the Wing Cap, the player can hold to slow down Mario's descent. Mario also does not take any damage from falling if he was launched out of a cannon. Like the Super Leaf and the Cape Feather, the Wing Cap allows Mario to fly. The wings will last for about 20 seconds.
While Wing Mario returns in Super Mario 64 DS, the Wing Cap doesn't, as it's replaced by a feather that only Mario can use, which can drop from red ? Blocks. The form still works as it did in Super Mario 64. It is not possible for Yoshi, Wario, or Luigi to acquire wings in the single player mode of the game. However, the feathers are located in two of the game's multiplayer stages: Sunshine Isles and Battle Fort. They add wings to their cap regardless of who picks them up. In the case of Yoshi, he grows wings on his body.
The Wing Cap theme also plays when Mario rides on a Green Shell or becomes Vanish Mario. Also, in the Nintendo DS remake, a slower-paced version plays when Hoot is carrying Mario, and when Mario turns into Balloon Mario after obtaining a Power Flower.
This theme is a cover of the music heard when Baby Mario transforms into Superstar Mario, as well as the music heard in certain bonus rooms in Super Mario World 2: Yoshi's Island, which in turn is a cover of the music that plays when Mario acquires a Super Star in the original Super Mario Bros., but with an added melody. The theme was reused in New Super Mario Bros. as the invincibility theme, and was later remixed for Super Mario Galaxy and Super Mario Galaxy 2 for the equivalent Rainbow Star power-up.
