Japanese Commercial#

Watch on YouTube
A commercial for the game shows Autobombs firing large Bullet Bill-esque bullets instead of fireballs. The Autobombs themselves also moved much more slowly than their final counterpart.

Manual Screenshots#

Unused graphics and level designs for Doki Doki Panic are seen in the Japanese commercial and the manual, as well as promotional material for the game.

Early Graphics#

Manual	Final

The top part of the key is wider and has no transparency in the hole.

Manual	Final

The mask is shown with red rather than white, with a wider top and different pattern. The final design's color scheme more closely resembles the majority of the actual Mardi Gras masks that were given out at the Yume Koujou festival.

Manual	Final

Porcupo's sprite is shown being colored white rather than tan (matching its artwork) and with actual legs, implying it had a proper walking animation. In the final game, the Porcupo is made up of a single static sprite whose front half "wriggles" to simulate movement. It's possible that the animation had to be simplified in order to fit Tweeter's sprite into the enemy graphic bank, as it was seemingly a late addition (see below). Porcupo would be given a proper walking animation in the Super Mario All-Stars version of Super Mario Bros. 2

Manual	Final

The Autobomb's "M" is smaller and red rather than white.

Unused Enemies#

Mentioned only in the manual, the Gray Shy Guy was cut from the game at some point in development and replaced with Tweeter, as evidenced by its sprite ID falling in between the Red and Pink Shy Guys (the Gray Snifit's sprite ID also falls between its Red and Pink variants) as well as the fact that Tweeter is not mentioned in the manual despite being a rather common enemy. The manual refers to it behaving similarly to Flurries but at a slower speed, following the character's position by automatically turning in their direction. A small remnant of this behavior remains in the final game: if a Tweeter is followed for several screens, it will eventually turn around.

Oddly, while the manual contains an entry for the Gray Beezo that is used in the final game, the screenshot accompanying it appears to show it using the pink palette. This does not appear to be a result of a poor quality screenshot, as other gray enemies in the manual like the aforementioned Gray Shy Guy are properly depicted as gray in their screenshots. The Super Mario Bros. 2 manual would end up labeling the Gray Beezo as pink as a result of this, an error that would carry over to most future SMB2 material, including its entry on the game's official webpage.

Level Screenshots#

A number of pictures show what are either early iterations of levels from the final game, or levels that were entirely replaced. At this point in development, the background log objects use a brown palette; this was likely changed to red to match the falling log sprites.
