Mushroomy Kingdom

Mushroomy Kingdom is a stage in the Wii video game Super Smash Bros. Brawl. The stage is an exact replica of World 1-1 of Super Mario Bros., though apparently age has come into play and the entire area has become a desert with pleny of ruins. The stage will slowly scroll right, meaning you'll have to attack your opponents and continue moving during the whole engagement. Once selected, you may also appear in World 1-2, the first underground segment of Super Mario Bros.

The entire stage has been abandoned by all enemies as well, thus meaning you won't have to bother with Goombas and Koopa Troopas.
