History YMMV / DokiDokiPanic

** For decades, the only substantial information on the festival this game was created as a tie-in for, ''Yume Kōjō'', was entirely unknown outside of Japan, and to this day, searching the name of the event will give you links about the game instead. A [=YouTube=] channel called GTV Japan is your best source for learning about the actual event in English.

** The 1-Ups in this game were the head of your chosen character. ''[=SMB2=]'' changed this to a type of mushroom[[note]]Although they were simply orange-brown with "1up" on them, as opposed to the now-standard green 1-Up Mushrooms[[/note]]. Also, the hawk-like mask gate at the end of each stage was originally a slightly scary tiki-like mask. World 7's vegetables were mean-looking, and the mushroom blocks were menacing masks.
** {{Inverted|Trope}} with Phanto, who looked like a generic opera mask in this game. Strangely enough, the instruction manuals for ''Super Mario Bros. 2'' and ''Super Mario Advance'', as well as Phanto's appearance in ''WesternAnimation/TheSuperMarioBrosSuperShow'', would use the original ''Doki Doki Panic'' design.

* ValuesDissonance: The turtle shell of ''[=SMB2=]'' was a {{Blackface}} ShrunkenHead called "Big Face" in this game, which was much more acceptable in Japan than it would be in America.

* Padding: You have to beat every level with every character to see the true ending, meaning you have to play through the game ''four times''. It's not a wonder that ''[=SMB2=]'' changed this to only requiring the player to beat the game once and gave players the ability to switch characters between levels.

** Safe to say this game is way more famous than the 1987 Fuji TV promotion on which it's based.
** And this game itself is displaced by its ''Mario''-ified adaptation, ''VideoGame/SuperMarioBros2''.

* MemeticMutation: "Did you know that ''VideoGame/SuperMarioBros2'' was originally a different game called ''Doki Doki Panic''?"[[labelnote:Explanation]]This fact, while once considered a legitimately interesting and scarcely-discussed piece of ''Mario''-series trivia, ended up becoming the subject of backlash in the late 2010s and early 2020s thanks to how damn-near every video game-related trivia outlet and know-it-all fan kept repeating it as if it was still a hugely obscure fact, even after the info was spread so heavily that it became common knowledge. As a result, it's often now brought up mockingly as a way of making fun of those who still treat it as obscure information, as well as in response to other reiterations of once-obscure but now well-documented pieces of trivia about popular video games.[[/labelnote]]
** Related to the above, claiming that ''VisualNovel/DokiDokiLiteratureClub'' is somehow connected to this game and ''Super Mario Bros. 2''.

** [[DistaffCounterpart Mama]] was simply an ActionMom, and her character was replaced with Luigi. Coincidentally, a few years later, the animated version of ''WesternAnimation/SuperMarioWorld'' launched an episode called "Mama Luigi", which would later become an internet meme thanks to various WebAnimation/YouTubePoop videos.

* WhatAnIdiot: You would think that Wart would have removed the malfunctioning Dream Machine that's spitting out vegetables everywhere, given that vegetables are [[WeaksauceWeakness his one weakness]]. Apparently, he's perfectly content with fighting the PlayerCharacter [[TooDumbToLive while the machine is operating in the area]]. To add further to Wart's stupidity, the Dream Machine is ''right in front of him''.

* AnticlimaxBoss: This game's incarnation of Wart, despite being fundamentally the same boss fight as in ''VideoGame/SuperMarioBros2'', is a pathetically easy final boss due to only requiring four hits to defeat, along with it being very easy to throw vegetables down his throat. For ''[=SMB2=]'', the number of hits required to defeat him was increased to six, along with his attack pattern being tweaked so as to make it harder to damage him.
