List of Mario & Luigi: Superstar Saga pre-release and unused content

These are 'beta elements from Mario & Luigi: Bowser's Inside Story.

Beta Elements
Wario, Fox McCloud, Captain Olimar, Samus Aran, Link, and even an Excitebike Racer were going to show up in the Starbeans Café after Mario and Luigi made coffee, instead of E. Gadd (who was only scheduled to make one appearance).

A few unused items include Neon Beans, a Game and Watch, and an item known as the "Spiritual Bros." , which may have been intended to be a badge. A badge named Soulful Bros. does exist. Therefore, Nintendo may have attempted to rename this item. Originally, the Bean Fruits were each intended to be a different color, rather than the identical bean fruits of the final game.

The name "Sharkbone" appears alongside names for enemies found in Gwarhar Lagoon in the game's coding. "Sharkbone" is presumed to be an alternate name for the ???? enemies that are actually found in the final game, as these enemies actually can come in a bony shark form, although they are also found in a living, Cheep-Cheep-like variety. A Nintendo Power guide actually referred to the ????s' undead shark forms as "Sharkbones" and their living Cheep-Cheep forms as "Puffer-Cheeps", the latter being Cheep-Cheep varieties present in the final game. It is presumed that Nintendo Power based this naming off of beta material. It may also be worth noting that the German version of Mario and Luigi: Superstar Saga replaces "Sharkbone" with "Sand-Cheep" ).
