Fawful Arena is a stage in Mushroom Kingdom Showdown. The stage features a flat surface with fall-off on both sides. It is categorized as an allowed stage. It is a walk-off stage, but the size is large enough and is completely flat.
- Along with Bowser's Island, Wario's Throne, Forest Maze, Peach's Castle, and E.Gadd's Lab, Fawful's Arena is one of six stages to have an owner (Fawful).
- Fawful Arena was also the first stage to have an owner.
- The stage's general appearance is taken from Peach's Castle in Mario and Luigi: Bowser's Inside Story (somewhere at the end of the game).
