List of Super Mario 3D World pre-release and unused content

This is a list of beta elements of the game Super Mario 3D World.

E3 2013
The courses presented in the demo did not have alternative names. The level placements were also changed; in the final build, the courses present in the demo are:
 * World 1-5: became World 1-4: Plessie's Plunging Ride.
 * World 2-1: World 2-4: Really Rolling Hills in the final version.
 * World 4-2: changed to World 6-1: Clear Pipe Cruise.
 * World 4-Boss: changed to World 3-B: A Banquet with Hisstocrat. There is no level called World 4-Boss in the final game.
 * World 6-3: World 6-5: Bullet Bill Base in the release game.

Some levels and elements have undergone some changes:
 * The panels in the bonus room from Really Rolling Hills had different colors. The area where the third Green Star is found did not have a Rectangular ? Block. This level also contained Goombas.
 * Bullet Bill Base had normal trees, later replaced by beanpoles.
 * Hisstocrat didn't hiss while calling his underlings.
 * Fort Fire Bros. had red lava instead of blue lava.
 * The Goal Pole at the end of a course did not have a golden flag when the player reaches the top. A small star, however, appeared and moved off-screen in its place. Hitting the top would grant the players one Extra Life as well as points.
 * Captain Toad's character icon is different; it features him without his adventure wear. Also, it has a blue background, instead of brown like the final version. The vest is also blue in the pictue, just like Toad himself.
 * There are no instances where there are instructions on how to play the game.
 * Mario also reuses his voice clips from Super Mario 3D Land in the trailer and demo. In the final version, he has completely new voice clips. The other characters would have also reused voice clips from previous games.
 * Stamps are not present in any of the courses.
 * The final score is not presented on the level start screen wipe.
 * During the trailer and demo, the power-up sound effect used when collecting a Super Bell is the same as when collecting any other standard power-up, reused from Super Mario 3D Land, but with a small added bell jingle. In the final version, the power-up is given a different sound clip, but still contains the old one.
