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 all over 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 and 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 3rd favorite choice, with many other forms of water-pump functionality suggested. One other notable device in the top 2 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 you 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.

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. .
