Mushroom Kingdom (SSBM)
Mushroom Kingdom (いにしえの王国, Ancient Kingdom) is a starter stage in Super Smash Bros. Melee. It is Mario and Luigi's home stage. In All-Star mode, this stage is played on when Luigi and any of his teammates are faced.
This stage originates from the NES game Super Mario Bros. Blocks are prominent in Super Mario Bros., more particularly Question Blocks and Brick Blocks. When a Question Block is hit from below, it will release an item. Brick Blocks typically do not contain items, and if the player has a Super Mushroom, that person can break them. All of the aforementioned is retained in Melee except that players do not have to hit blocks from below to get an item, nor do they have to have a Super Mushroom to break Brick Blocks. The floating platforms in Melee that are above the two pits also originate from Super Mario Bros. There is also many elements in the background that can be seen, all of which come from Super Mario Bros. in their original 8-bit form. For example, Goombas, a flag pole, tall mushrooms, etc. 
There are two tracks that are used in this stage. One of which comes directly from Super Mario Bros.' above ground theme. Also, just like Super Mario Bros., when the timer runs low, a sped up version of the music will play. The other track is a remixed version of the track Fever from the puzzle game Dr. Mario. 
The stage is split up into three sections: two small platforms on the left and right, and one main one in the middle. Between the outer ones are two pits. Over the right and left platforms, there are three blocks while the middle platform has two rows of blocks above it. All the boxes are bricks, except those with flashing "?" marks. This blocks can be broken, and breaking the "?" blocks will produce an item. Once in a while all the boxes will reappear as "?" boxes. There are also two floating platforms, each above a pit. If players stand on one too long, it will break off and fall into the pit, reappearing a few seconds afterwards. The speed of the falling platform depends on characters weight. The lighter the characters is, the slower the floating platform will fall. Noticeably, but often unspoken of by Smash Bros. players, the Melee version doesn't use warp pipes like the original. However, by pausing and turning the camera, warp pipes that exit in the pits like in the original are visible but are behind the playable area of the stage and cannot be entered. If one pauses and turns the camera all the way to the right or left, a black wall with a word that says DANGER can be seen, which is appropriate as those areas are past the side blast lines.
Due to it having caves of life due to the bricks on the stage, as well as walk-off blast-lines and an irregular design, Mushroom Kingdom is banned in tournaments.
