List of Super Mario Sunshine pre-release and unused content

This article pertains to the Beta elements of Super Mario Sunshine.

Beta elements
In Super Mario Sunshine, Delfino Plaza is the main plaza of the game. However, in movies before release, it showed that there was going to be a different plaza (or possible prototype for Delfino Plaza), with a giant Strollin' Stu-like creature walking around the place and many more different things. The beta also reveals that Humans were intended to be citizens of the plaza. F.L.U.D.D. was going to be skinnier. Gooper Blooper was going to be dark blue and fought on top of the bridges of Ricco Harbor instead of in the market and helicopter area.

Additionally, Mario's health bar would simply be a sun with a number in the middle indicating his health. The water meter was originally placed in the center of the "sun" life meter. The F.L.U.D.D. pack was actually Nintendo's third favorite choice, with many other forms of water-pump functionality suggested. One other notable device in the top two was a water gun but was abandoned deciding that some players may render it too violent. There were some abandoned sprites as well, including Yoshi vomiting any water he may have swallowed. There was also going to be a brown Pokey species, which was going to have white flowers.

A book is found behind a door in some ruins-like structure in Episode 3 of Noki Bay. The player can see it by turning the camera. There is a glitch in the game that allows Mario to reach the book, but there is no known way to get out of the structure. (The door does not work from any side and it looks different from the doors in the hotel in Sirena Beach.) This may be a beta element, easter egg, or just a detail that was never meant to be taken seriously.

Another interesting thing to note, is the appearance of a sewer cover in the jail cell (containing a blue coin) during the events of the flood. It is possible that there was originally going to be a sewer leading to this room instead of the entrance behind the building, and that this detail was overlooked in the model/map of Delfino Plaza during the flood. It is possible to get into the cell during the flood via multiple glitches or hacking, but like all other submerged sewer covers it does not work (and is actually just a texture on the floor).

A test level is playable through an Action Replay. There the player can see Rock Blocks that were edited out, possibly in favor of Watermelons. . The giant Strollin' Stu appeared but didn't have his shell-like thing, it is hard to see him since he dies right when the level starts. There was also a Noki that was covered with goop in the level. When Mario finished cleaning him, Mario could see he didn't have a shell.
