'''''Yume Kōjō: Doki Doki Panic''''', usually referred to as simply '''''Doki Doki Panic''''', is a [[Japan]]-exclusive platform game developed by [[Nintendo]] in cooperation with {{wp|Fuji Television}} (who also published ''[[All Night Nippon: Super Mario Bros.]]'') for the [[Family Computer Disk System]] to promote its event called [[#Yume Kōjō '87|Yume Kōjō '87]] (translates to "Dream Factory '87").

The game was later released outside Japan in an altered format under the name ''[[Super Mario Bros. 2]]'', since the original Japanese ''[[Super Mario Bros.]]'' sequel, ''[[Super Mario Bros.: The Lost Levels]]'', was deemed too similar to the original and too difficult for overseas players. Eventually, the altered [[Super Mario (franchise)|''Super Mario''-franchise]] version of ''Doki Doki Panic'' was released in Japan as well, under the title ''Super Mario USA'', with {{file link|SMUSA FC Box.png|its box art}} being a recreation of ''Doki Doki Panic''{{'}}s, with the ''Yume Kōjō'' characters replaced with [[Mario]], [[Luigi]], [[Princess Peach|Princess Toadstool]], and [[Toad]].

==Story==
The game takes place inside a storybook. The book's story tells of the dream world of Muu, where the quality of dreams determines the quality of the weather the next day. Because of this, the Muu citizens invented a [[Dream Machine|dream machine]], so they could always have good dreams. One day, a mischievous being named [[Wart|Mamu]] (whose name was changed to Wart for ''Super Mario Bros. 2'') invaded the land and used the dream machine to make nightmarish monsters. However, the Muu people learned of his weakness to vegetables and used them to defeat him.

The old storybook had found its way into the hands of a pet monkey, Rūsa, who gives the book to the young twins Poki and Piki. However, the twins quarrel and end up ripping out the last page of the book, causing its ending to be erased. Mamu, freed, reaches through the pages and kidnaps the twins, pulling them into the book. Rūsa gets the twins' parents, Mama and Papa, their brother, Imajin, and Imajin's girlfriend,<ref>{{cite|author=Gaijillionaire|language=en|date=July 17, 2016|url=www.youtube.com/watch?v=KL9o9zzCUsQ&t=8m38s|timestamp=08:38|title=Yume Kojo!

==Impact on the ''Super Mario'' franchise==
The ''Doki Doki Panic'' engine started as a ''Super Mario''-style tech demo using vertical-scrolling mechanics as opposed to side-scrolling mechanics.<ref>{{cite|language=en|author=Kohler, Chris|date=April 1, 2011|url=www.wired.com/2011/04/super-mario-bros-2|title=The Secret History of ''Super Mario Bros. 2''|publisher=Wired|accessdate=July 25, 2015}}</ref> [[Shigeru Miyamoto]] suggested the inclusion of side-scrolling mechanics to make it more of a ''Super Mario'' concept. Nintendo entered a licensing deal with Fuji Television, and the game's development proceeded with ''Yume Kōjō'' characters. Shigeru Miyamoto, as a result, was more involved with the development of ''Doki Doki Panic'' than he was in what eventually became the [[Super Mario Bros.: The Lost Levels|original ''Super Mario Bros. 2'']]. Many of the game's enemies would become generic ''[[Super Mario (franchise)|Super Mario]]'' enemies, though many were not intended to be that at the time of their creation. This includes [[Shy Guy|Shyguy]]s, [[Birdo]]s, [[Pokey]]s, [[Bob-omb|Bob-Omb]]s, and numerous others. Of particular note is how [[Mario]], [[Luigi]], [[Toad]], and [[Princess Peach|Princess Toadstool]]'s skills and attacks have been shaped by the skills of the characters they replaced.

Some ''Super Mario'' elements had already been in place prior to the overhaul for America - both [[POW Block|POW]]s (from ''[[Mario Bros. (game)|Mario Bros.]]'') and [[Super Star|Star]]s (from ''[[Super Mario Bros.]]'') are frequent and powerful items that serve the same purposes as in their games of origin.

|align="left"|Mama has a high jump, but she is weaker than average. She is slightly slower than average as well.
|align="left"|Papa is the fastest and the strongest. He has the lowest jump in the game, however. Due to his poor jumping ability, he relies heavily on the charged jump.
|align="left"|Lina has a special float jump that allows her to hover in midair, which can be used to jump further or correct an otherwise fatal landing. As a tradeoff, she has the lowest speed and power.

==Differences between ''Yume Kōjō: Doki Doki Panic'' and ''Super Mario Bros. 2''==
Several changes were made in order to make the game appropriate for the ''Super Mario'' franchise. Graphical changes were made for certain enemies and characters. Additionally, the cream white [[Mouser]] boss featured in [[World 5-3 (Super Mario Bros. 2)|World 5-3]] was replaced with [[Clawgrip]]. This change was in tune with the decision to release the edited ''Doki Doki Panic'' in place of the Japanese ''[[Super Mario Bros.: The Lost Levels|Super Mario Bros. 2]]'', which Nintendo of Japan feared was too hard for European and American gamers.<ref>{{cite|language=en|author=NintenDaanNC|date=December 7, 2010|url=www.youtube.com/watch?v=DNa0M1gymgA|title=<nowiki>[NC US]</nowiki> Super Mario Bros. 25th Anniversary - Interview with Shigeru Miyamoto #2|publisher=YouTube|accessdate=April 4, 2011}}</ref>
===Characters===
[[File:DDP SMB2 Characters Comparison.png|frame]]
*'''Imajin''' is the balanced character. While [[Mario]] replaces him, Imajin's balance in all areas has since become a staple of Mario's in many games where there are multiple playable characters.
*'''Mama''' has the ability to jump higher and lightly hover at the top of her jumps. [[Luigi]] takes her place as he had already had higher jumps than Mario in ''[[Super Mario Bros.: The Lost Levels]]''. However, Luigi can jump slightly higher than Mama. Like his brother's balanced stats, his higher jumps have stayed in the ''Super Mario'' franchise.
*'''Lina''' can briefly hover, but she is low in speed and strength. [[Princess Peach|Princess Toadstool]] replaces her. As a result of the license with Fuji Television expiring, Peach inherited [[Floating Jump|Lina's floating capability]], and the concept of Peach being able to float reoccurs in many video games. Games in the ''[[Super Smash Bros. (series)|Super Smash Bros.]]'' series starting with ''[[Super Smash Bros. Melee]]'' (her first appearance in that series), as well as ''[[Super Mario 3D World]]'', use similar mechanics to this game.
*'''Papa''' is the strongest character in the game and can run the fastest, though he is not very good at jumping. [[Toad]] takes his place, and while the idea of him being a strong character does not often reoccur in future video games (It is referenced in ''[[Wario's Woods (Nintendo Entertainment System)|Wario's Woods]]'' and ''[[Mario Superstar Baseball]]''), Toad being an especially fast character has since become a staple in games with multiple playable characters. ''Super Mario 3D World'' reincorporates the lacking jump.
*'''Poki''' and '''Piki''' are non-playable characters who get captured by Mamu at the beginning of the game and are rescued after his defeat. They are replaced by the [[Subcon (species)|Subcons]] in ''[[Super Mario Bros. 2]]'', which are also present in ''Doki Doki Panic''{{'}}s endings.
*'''Rūsa''' is a non-playable monkey who gives Poki and Piki the old storybook that gets both kidnapped by Mamu.

===Gameplay===
*The player must beat the game with all four characters to view the ending in ''Doki Doki Panic'', unlike ''Super Mario Bros. 2'', where the player only needs to beat the game once to view the ending. However, due to ''Doki Doki Panic'' being on the Disk System, each characters' progress through the game was independently saved and could be returned to at a later date.
*A save feature is included.
*The player cannot run by holding the {{Button|nes|B}} button.
*Imajin, Lina, Papa, and Mama do not [[Small Mario|shrink]] when they have one hit point left.
*In ''Doki Doki Panic'', knocked-out enemies cannot knock out other enemies as they proceed to fall off the screen, whereas in ''Super Mario Bros. 2'', enemies can be comboed with careful throws.<ref>{{cite|author=Shesez|date=February 11, 2022|url=www.youtube.com/watch?v=uDQq8Im2hVI&t=2040s|timestamp=34:00|title=ALL Differences Between Mario 2 and Doki Doki Panic - Region Break|publisher=YouTube|accessdate=March 12, 2022}}</ref>
*It takes four hits for Mamu to be defeated in ''Doki Doki Panic'', as compared to six in ''Super Mario Bros. 2''; this is also present in the prototype version of ''Super Mario Bros. 2''.
*An albino version of [[Mouser]] appeared as the boss of 5-3. In ''Super Mario Bros. 2'', he was replaced with [[Clawgrip]], who is the only boss exclusive to ''Super Mario Bros. 2''.
*The type of Ninji that hops in place has three jump heights in ''Doki Doki Panic''; ''Super Mario Bros. 2'' only includes the low and high jump.
*The highest cloud platform in a section of 7-1 was removed, and the gray [[Snifit]] was moved onto a pillar where the cloud was once attached to.
*The shortcut in 6-3 is slightly different: in ''Doki Doki Panic'', one can simply jump down from the cloud platform with the door; in ''Super Mario Bros. 2'', two more cloud platforms stand between the door and the ground.

===Visuals===
*The title screen is entirely different.
*Rather than the storyline taking place in a dream world, it takes place within a storybook. The plot of the game is about two kids named Poki and Piki who fought over reading a book and ended up getting themselves pulled in by [[Wart|Mamu]] after accidentally tearing out the last page. A monkey known as Rūsa witnessed this and alerted the family.
*In ''Doki Doki Panic'', the intro screens of the levels were actually pages from the storybook; levels were referred to as "Chapters", page number marks that were commonly used in story books appeared, and the intro screens lacked the location icons. In ''Super Mario Bros. 2'', the intro screens were heavily edited to make them look like cards since ''Doki Doki Panic''{{'}}s story settings were from a storybook instead of a dream; the text "Chapters" was changed to "Worlds", the page number marks were completely removed, and location icons were added.<ref>{{cite|author=VCDECIDE|language=en|date=October 18, 2015|url=www.youtube.com/watch?v=fXyHr3ZuVc8&t=46s|title=Regional Differences <nowiki>[04]</nowiki> Super Mario Bros. 2 vs Yume Kōjō: Doki Doki Panic (Nes vs Famicom)|publisher=YouTube|accessdate=February 26, 2018}}</ref>
*The characters and artwork are based on an Arabian-style theme.
*After leaving a [[key]]'s home room, a [[Phanto]] inexplicably begins assaulting the player out of nowhere. In ''Super Mario Bros. 2'', the Phanto now appears, albeit stationary and seemingly harmless, in the key's home room; however, once the key is retrieved, the Phanto comes to life and begins attacking.
*[[Red Shell|Shell]]s replace the Big Face item, which were heads resembling {{wp|blackface}}. They were edited due to the controversy over blackface mocking people of African ancestry.<ref>{{cite|author=TCRF|title=[[tcrf:Super Mario Bros. 2 (NES)/Regional_Differences#Koopa_Shells|''Super Mario Bros. 2'' (NES)/Regional Differences]]|publisher=The Cutting Room Floor|accessdate=August 6, 2023}}</ref>
*[[Magical Potion]]s were originally [[Genie Lamp|Magic Lamp]]s. Magic Lamps were also present in the prototype version of ''Super Mario Bros. 2'', as the Magical Potions were not implemented yet. 
*[[Mushroom]]s were originally [[heart (item)|heart]]s.
*[[1-Up Mushroom]]s were originally the heads of the character being controlled.
*[[Grass]] tufts were black instead of red.
*[[Mask Gate]]s were originally generic masks instead of hawk masks.
*The explosion icon says "BOM" in ''Doki Doki Panic'', and "BOMB" in ''Super Mario Bros. 2''.
*[[Phanto]]s originally had a less menacing appearance.
*[[Mushroom Block]]s were originally various masks.
*Some [[vegetable]]s looked slightly different.
*[[Cherry|Cherries]], [[POW Block|POW]]s, [[vine]]s, [[grass]] tufts, [[Crystal Ball]]s, [[bomb]] fuses, water, cloud platforms, and [[Spike Trap|spike]]s are still, unlike in ''Super Mario Bros. 2'', where they are animated.
*[[Albatoss]]es have only two frames of animation, while ''Super Mario Bros. 2'' gives them eight (with only seven showing up outside of remakes due to a glitch).<ref>{{cite|author=TCRF|title=[[tcrf:Super Mario Bros. 2 (NES)#Eighth Animation Frame|''Super Mario Bros. 2'' (NES)#Eighth Animation Frame]]|language=en|publisher=The Cutting Room Floor|accessdate=July 20, 2018}}</ref>
*Waterfalls and the fast quicksand animate faster than in ''Super Mario Bros. 2''.

===Sound===
*The title screen music is completely different from that of ''Super Mario Bros. 2'', which is an arrangement of the ''Super Mario Bros.'' [[Underwater Theme]]. This title screen music would later serve as the basis for the ending music of ''Super Mario Bros. 2'' when Mario is seen sleeping.
*Sound effects are changed, as the Disk System adds audio hardware not present in the [[Nintendo Entertainment System|NES]].
*The [[Subspace|Sub-space]] music for ''Super Mario Bros. 2'' is the overworld theme for ''[[Super Mario Bros.]]'', while the music for ''Doki Doki Panic'' is an Arabian theme.
*''Super Mario Bros. 2'' adds entirely new sections of music to the existing player select and overworld themes from ''Doki Doki Panic''.
*Upon grabbing the [[Super Star|Star]], an Arabian-sounding tune plays in ''Doki Doki Panic'', while the standard ''Super Mario Bros.'' Star fanfare plays in ''Super Mario Bros. 2''.
*Most music tracks reused from ''Doki Doki Panic'' in ''Super Mario Bros. 2'' sound slightly different from each other; the underground theme, for example, is slightly faster and lacks the bongo percussion in ''Doki Doki Panic''.

==Yume Kōjō '87==
''Doki Doki Panic'' was based on '''Yume Kōjō '87''', an event sponsored by Fuji TV and held from July 18th to August 30th, 1987. On the last day of this event, there was a grand finale.<ref>{{cite|author=Gaijillionaire|date=July 17, 2016|url=www.youtube.com/watch?v=KL9o9zzCUsQ&t=1031s|timestamp=17:11|title=Yume Kojo! Not The Story of Super Mario Bros 2 vs Doki Doki Panic Nintendo NES History Fuji TV ｜　Gテレ|publisher=YouTube|language=en|accessdate=April 4, 2017}}</ref> This finale was meant to introduce a new generation of media that would arrive in the years to come, with various technical displays, as well as to advertise Fuji TV's fall lineup of shows. Elements from the event carried over to the game include the characters of Papa, Mama, Imajin, Lina, Poki and Piki, the blimp on the title screen, and the use of masks as a visual motif.

==References in later media==
*[[Super Mario (Kodansha manga)|''Super Mario'' (Kodansha manga)]]: During the ''Super Mario USA'' adaptation, [[Princess Peach]], trapped in [[Subspace|Sub-space]], finds a Magic Lamp from ''Doki Doki Panic''. [[Birdo]] states it is useless and instead pulls out its ''Super Mario Bros. 2'' equivalent, the [[Magical Potion]].
*''[[Mario Kart 8]]'' / ''[[Mario Kart 8 Deluxe]]'': On [[Toad Harbor]], there is a sign saying "Shy Guy Metals: Since 1987", referencing this game's release date and the introduction of the [[Shy Guy]]s.
*''[[Super Mario 3D World]]'': The player being required to beat all levels with all characters (Mario, Luigi, Toad, Princess Peach, and [[Rosalina]]), barring the [[Captain Toad]] levels, in order to unlock all related stamps and all five profile stars is similar to how the player was required to beat all levels with all characters (Imajin, Mama, Papa, and Lina).
*''[[Super Smash Bros. for Wii U]]'': The [[List of trophies in Super Smash Bros. for Wii U|trophies]] for Birdo and Shy Guy mention that they actually debuted in ''Doki Doki Panic'' (the ''Yume Kojō'' part of the title is not mentioned in English versions).
*''[[Paper Mario: Color Splash]]'': During her concert in [[Plum Park]], Birdo sings the line "two hearts in doki doki panic," referencing this game's title.
*''[[Paper Mario: The Origami King]]'': One of the terms [[Bob-omb (Paper Mario: The Origami King)|Bob-omb]] uses to refer to his amnesia is "Thinky Thinky Panic", referencing this game's title, which was where Bob-ombs were first introduced.

==Names in other languages==
{{foreign names
|Jpn={{ruby|夢|ゆめ}}{{ruby|工場|こうじょう}}ドキドキパニック
|JpnR={{nw|Yume Kōjō: Doki Doki Panikku}}
|JpnM=''Yume Kōjō'' means "Dream Factory", while ''doki doki'' is Japanese onomatopoeia for a rapidly beating heart and ''panikku'' is a transcription of the English "panic", so in effect, it can be translated as "Dream Factory: Heart-Pounding Panic".}}

==Notes==
*The coin counter in [[Bonus Chance]] segments is displayed in {{wp|hexadecimal}}. When the player gets more than nine [[coin]]s in a level, letters from A to F are used instead.
*Despite appearing in the manual, no gray Shyguys or pink Beezos appear in the game.
*Coincidentally, some promotional material features Imajin and Lina posing with Mario and Princess Peach, their eventual replacements in ''Super Mario Bros. 2''.<ref>{{cite|author=Mackie, Drew|date=June 21, 2023|url=www.thrillingtalesofoldvideogames.com/blog/super-mario-bros-2-missing-level|title=Why Is Super Mario Bros. 2 Missing a Level?|publisher=Thrilling Tales of Old Video Games|accessdate=June 23, 2024}}</ref>
*A possible reason why the game has seen no re-releases outside of ''[[Super Mario Bros. 2]]'' is because the rights of ''Yume Kōjō'', along with its characters, like Imajin, are owned by {{iw|wikipedia|Fuji TV}}.
