The P-Wing is a special item that first appears in Super Mario Bros. 3. The "P" stands for Paratroopa or Patapata (the Japanese name for that enemy). It is a successor to the power-up simply known as the Wing.
Super Mario series
Super Mario Bros. 3
In Super Mario Bros. 3, the P-Wing allows Mario or Luigi to fly in the air with their Raccoon forms for an unlimited amount of time. However, if the brothers are hit or receive a non-flying-based power-up within a level, they will lose the power of the P-Wing. Additionally, the effects of the P-Wing only last until the level ends. After that, the brothers are left with their basic Super Leaf abilities.
If a P-Wing is used from the map screen, the letter "P" on Mario or Luigi's body (as shown in the sprite on the left) indicates that they have P-Wing abilities. The letter "P" isn't seen in the actual level or on the map screen after the level is completed.
The P-Wing can be combined with the Tanooki Suit. However, in order to do this, one must use a P-Wing, then enter a level that has a Tanooki Suit hidden within it (World 4-5, World 5-5, World 6-3, or World 7-) and collect that Tanooki Suit without losing the P-Wing's power.
P-Wings are commonly found in chests left behind after defeating certain Hammer Bros. on the map screen. They can also be found in secret white Toad Houses (blue in the game's remakes) accessible via collecting a certain amount of coins in a certain level of a world. However, P-Wings can only be found in the white Toad Houses of odd-numbered worlds (i.e. World 1: Grass Land, World 3: Water Land, World 5: Sky Land, and World 7: Pipe Land) - the even-numbered worlds' white Toad Houses contain Anchors. Additionally, by beating the game and restarting without resetting the game, the player is rewarded with twenty-eight P-Wings in their inventory.
Super Mario 3D Land
In the Nintendo 3DS game Super Mario 3D Land, the P-Wing functions differently, warping Mario to the end of the course. If Mario touches a P-Wing, it will go into storage to use later. It only appears if Mario or Luigi loses 10 lives in a (skipped) normal world level (making P-Wing Assist Blocks appear), or within certain Mystery Boxes. Mario will lose the P-Wing if he gets any other power-up (excluding a Super Star, or Invincibility Leaf, as the P-Wing will be replaced if Mario is in Super form or better).
New Super Mario Bros. 2
The P-Wing is seen as an icon on the Power Meter in New Super Mario Bros. 2, replacing the "P" icon in the meter's original appearance in Super Mario Bros. 3. Both the Power Meter and the P-Wing appears when Mario or Luigi gets a Super Leaf (i.e. turns into raccoon form).
