Tied with Indigo Plateau and Green Greens as the very first stage to debut on Super Smash Stadium, Mushroom Kingdom 1 is an active stage on the show and the very first representation of the Mario series.
==Stage overview==
In its current form, the stage is essentially Mushroom Kingdom U from Smash 4 Wii-U. However, the stage does not change layouts; it's permanently stuck on the "Acorn Plains" layout. To make up for this, the course was widened a bit, and scale elevators as well as a row of ? Blocks and Bricks were all added. Hitting a ? Block will give you an item, while a Brick may give you an item (20% chance) or three (10%).
The following stage hazards appear at random:
*A vine similar to the one seen in Skyward Stalk, which temporarily adds platforms that ultimately all die after 30 seconds.
*Giant icicles that do extreme damage and knockback to anyone hit as well as freezing them. Their tops can be used as platforms, but attack an icicle too much and it breaks.
*Waterspouts, some of which (50% chance) have giant Urchins on them.
*Stretchy blocks, some of which act like they did in Super Mario World 1 and stretch vertically.
*Various other kinds of elevator.
*Nabbit, who may kidnap a character and kill them by taking them up off the top.
==Changes==
The stage has been in its current form since late March 2013, with the last major change to this field on its first playing in Season 47, in the fall of 2018.
*Originally, the stage resembled the Mushroom Kingdom from Smash 64. To that effect, the only real stage hazard was that Piranha Plants would sometimes come out of the two pipes on stage. Also, a POW Block would spawn every now and then. The pipes actually worked; however, they had a chance to spit a fighter out in the pit that the scale elevators were over, potentially leading to a death.
**On the very first week of SSS, the stage had a yellow background. It was likely changed to the more familiar blue after fans complained that their eyes were bleeding and that the yellow made everything hard to see.
*From 1982 to 2013, the stage resembled Mushroom Kingdom 1 from Super Smash Bros. Mêlée.
*From 2013 to 2018, the stage had elements of New Super Mario Bros. 2 in it. Coins were scattered all over the stage, and every now and then, a P-Switch would appear. Collecting 100 coins turned the fighter into a gold version of themselves for 15 seconds, during which they had Super Armor against all opposing attacks.
Prior to Season 38, this stage was unique in that whenever 60 seconds or less were left in a match, the level music was sped up. In that season, the game was changed to have all stages do this (except those with custom themes such as Mushroom Kingdom 2 and Distant Planet); however, this level was still unique in that the "time is running out!" music was taken directly from Super Mario Bros. 1. (The regular theme is a remix of the "Final Lap" theme from Mario Kart: Double Dash!!.)
==In its own universe==
The original two versions of this stage resembled a level from Super Mario Bros. 1. As noted above, the current version resembles Acorn Plains, from New Super Mario Bros. U; the stage gimmicks are all things that can be found either in that game or NSMBWii.
