Mushroomy Kingdom

Mushroomy Kingdom is a stage in Super Smash Bros. Brawl based off levels in Super Mario Bros. This stage is a 2.5D (3D structure in a 2D perspective) replica of the original World 1-1 with enhanced graphics and a deserted look. Ruins can be seen in the background and life is absent apart from the fighters. Game director Masahiro Sakurai stated in the stage's update on the Smash Bros. DOJO!! that he wanted to create the impression that the kingdom had been abandoned since its initial appearance in 1985, 23 years prior to the release of Brawl. This explains the '-y' added to the title.

The stage scrolls to the right slowly and you'll see familiar Mario landmarks like the flagpole and castle at the end of the level, but it keeps on scrolling. There are both destructible blocks, as well as 'question' blocks, which release an item when struck. '?' blocks that contained coins and power-ups in Super Mario Bros. will release multiple items if attacked more than once.

There is also a chance when Mushroomy Kingdom is selected that the stage will actually load a similar stage based off of World 1-2. This stage has many blocks that need to be destroyed to pass through, and ends at the same pipe that it did in Super Mario Bros, but players must jump over it for the stage to restart. Originally, this is where the first Warp Zone was situated. Its removal makes it the only feature of the two levels that was not recreated for SSBB.

Mushroomy Kingdom's side scrolling properties make it technically the largest stage. As the layout repeatedly loops, it could be argued that the stage is actually infinite. However, New Pork City is the largest non-scrolling Brawl-original stage.

Due to the side-scrolling nature, many official tournaments banned this stage.

Origin
This stage comes from Super Mario Bros.. Mushroom Kingdom is where the majority of where the Mario games take place. As stated before Brawl's game director Masahiro Sakurai said in the stage's update on the Smash Bros. DOJO!! that he wanted to create the impression that the kingdom had been abandoned since its initial appearance in 1985, 23 years prior to the release of Brawl. This explains the '-y' added to the title. This stage is an accurate repilica of the layout of levels 1-1 and 1-2 of Super Mario Bros.; however, there are no villians, the player can't go in pipes, and there is no Warp Zone from level 1-2 of Super Mario Bros.. In Super Mario Bros. players can jump to hit a fashing question mark block to get an item. Ordinarily the player can't break brick blocks, but when the player has eaten a Super Mushroom the player could jump and hit a brick block to break it. In this stage the ability to hit a question mark block to get an item is retained; however, the player can break brick blocks without the use of a Super Mushroom. At the end of the first three levels of the eight worlds the player would have to jump a flag pole to pull down the flag and then enter a small or large castle. In this stage the flag pole and a small castle can be seen, but the player can't jump on the flag pole or go inside the castle.

Trivia

 * Characters can be damaged if they are standing on a block and somebody jumps into it from underneath them, similar to Mario when he hits a block or a brick under a enemy.
 * On this stage, it is possible to dodge End of Day in the underground by standing on the very top for the duration of his attack.
 * Just like in the original Super Mario Bros., one can still hit the area where the invisible 1-UP blocks were and receive items.
 * The stage's scrolling speed (for both versions) is such that the stage makes exactly one loop in two minutes, the default time for a timed match.
 * Characters with stationary Final Smashes, such as Donkey Kong's Konga Beat and King Dedede's Waddle Dee Army, will slow down the scroll speed for the duration of the Final Smash attack.
 * Players can destroy the brick blocks when under the effects of a Poison Mushroom, despite the fact that it has been impossible throughout the entire Mario series to break said blocks when in a mini state.
