Power Balloon

A Power Balloon, sometimes shortened to P Balloon or P-Balloon, is an item introduced in Super Mario World. When touched, it inflates the playable character and allows them to float through the air like a balloon.

Super Mario World / Super Mario World: Super Mario Advance 2
In Super Mario World and its reissue, Power Balloons can be found in four levels: Donut Secret 1, Donut Secret 2, Forest of Illusion 1, and Tubular. The item's effect is to make whoever picks it up swell up and become Balloon Mario or Balloon Luigi, causing him to hover in the air. He will gradually float upwards if not moved by the player, but he is capable of moving in any direction for a limited amount of time. During this time, Yoshi cannot be ridden, nor can shells or other carriable items be grabbed. Mario or Luigi starts to puff in and out when the item is about to wear off, and when it does, he returns to normal size and drops out of the air. The level Tubular in the Special Zone requires the player to continually pick up new Power Balloons to maintain flight while they make their way across the level. If Mario or Luigi passes through a Giant Gate while under the effects of the Power Balloon, he will gain a bonus Super Mushroom.

If Mario or Luigi has the powers of a Super Mushroom, Fire Flower, or Cape Feather and grabs a Power Balloon, he will still have whatever powers he originally had as well as those of the Power Balloon. However, if he collects any of these items while under the effects of a Power Balloon, the Power Balloon's power will instantly wear off. Exclusively in Super Mario World: Super Mario Advance 2, when Mario or Luigi grabs a Power Balloon, the music becomes slightly slower than usual. Slow music also plays in Super Mario 64 DS while Mario is under the effects of the Power Flower.

The Power Balloon in the source code of the prototypes for the original SNES game originally was going to be red before it was changed into beige in the final game.

Super Mario Maker 2
Power Balloons were added to Super Mario Maker 2 in the version 3.0.0 update released on April 22, 2020, available only in the Super Mario World style. In this game, the Power Balloon item floats in place rather than floating away to the right, and it is now bright yellow rather than beige. The character's appearance also changes more drastically when the character obtains the item, with Mario's and Luigi's overalls and Toad's and Toadette's undershirts turning yellow with a letter P on them (the P is on Toadette's dress in her case), similar to what the P-Wing does. The functionality of the Power Balloon form was also altered, allowing the character to be fully in control of which angle and direction they are floating towards, as opposed to the original game's simple vertical and horizontal mobility. The time limit is also removed. In the nighttime ground theme, Power Balloons fly around in circles, eventually disappearing.

Super Mario World television series
The Power Balloon makes three appearances in the Super Mario World television series, most notably in the episode "Mama Luigi," where Luigi uses it to float safely down a chasm. Later in the episode, Mario uses it to re-inflate Luigi back to his normal shape after he is flattened. In the series, the Power Balloon is referred to as a magic balloon. It also appears in another episode, "Gopher Bash." The Power Balloon is the only non-invincible item Luigi is seen using in the show.

Super Mario-kun
The Power Balloon also appears in volume 6 page 111 of Super Mario-kun, being featured in a single chapter. It shows itself coming out of a ? Block.

The Super Mario Bros. Movie
In The Super Mario Bros. Movie, Power Balloons can be seen inside the antiques shop.
