Mushroomy Kingdom

Mushroomy Kingdom is a stage in Super Smash Bros. Brawl based off of World 1-1 of Super Mario Bros. This stage is a 3D 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 stage on Brawl.

Choosing the level
Mushroomy Kingdom has a randomizer script attached to it. When chosen at the Stage Selection screen, both the Ground and Underground levels have a 50% chance of loading. However, it is possible to guarantee which version of the stage is used by holding down a certain button as it is selected. Following is a guide to doing this with all four controllers using the default control schemes:

Ground
 * Gamecube Controller: X or Y
 * Classic Controller: Same as Gamecube
 * Remote & Nunchuk: C
 * Wii Remote: A

Underground
 * Gamecube Controller: L or R
 * Classic Controller: Same as Gamecube
 * Remote & Nunchuk: Z
 * Wii Remote: B

Trivia

 * Characters can be damaged if they are standing on a block and somebody jumps into it from underneath them.
 * None of the warp pipes are active in this stage. They are plugged by mesh lids, similar to the wooden ones in Melee's Mushroom Kingdom Adventure.
 * Olimar will crash through the ground and SD if he uses his Final Smash and lands where the stage loops (scrolls back to the beginning). The spots are the very last pipe in underground, and on the steps to the flag above ground.
 * Just like in the original Super Mario Bros., one can still hit the area where the invisible 1-UP block was and receive items.
 * When Ike uses his Final Smash (Great Aether) in the Underground, it will be a guaranteed KO if there are blocks along the top of the screen due to the fact that he flies to the top of the stage and with the final attack knocks foes over the top blast line.
