Mushroom Carnival

The Mushroom Carnival is the first playable stage of SSBGA's King of Stories stage. When Bowser and Descole's fleet captures Peach and Jigglypuff, Mario and Kirby pursue the fleet and rescue the victims. Mushroom Carnival is heavily influenced by Toad Town from the Super Mario Galaxy series. Playable characters are Mario and Kirby.

Layout
The layout of the stage is very simple, with only several enemies to defeat and it also has tutorials for the player on how to complete the rest of the stages. Toads can be seen in the background as cameos.
