* DevelopmentHell:
** Between ''Kirby's Air Ride'' and ''Kirby's Return to Dream Land'' (''Epic Yarn'' was developed by Good Feel instead), HAL Laboratories made repeated attempts to create a home console game for the ''Kirby'' series. Their most known attempt was the UsefulNotes/NintendoGameCube game, announced in 2004, and widely believed to be reincarnated as ''VideoGame/KirbysReturnToDreamLand''. However, [[http://www.nintendo.co.jp/wii/interview/sukj/vol1/index.html an interview]] revealed that the [=GameCube=] game was only the first of ''four'' attempts at a home console game, the final being ''Return to Dream Land''.
** ''Kirby Air Ride'' itself was trapped in DevelopmentHell for quite some time. It was originally intended as a UsefulNotes/{{Nintendo 64}} game, but after spending many years in production, it was quietly canceled. It finally showed up as a [=GameCube=] title at E3 2003.
* ExecutiveMeddling: Rumor has it that Masahiro Sakurai left HAL because this happened during the development of ''Air Ride''. He also didn't like the sequelization of the gaming industry.
* FanNickname: King Dedede is sometimes referred to as "DDD", "Triple-D", or "3D".
** The bandana wearing Waddle Dee that served as Dedede's right hand in ''Super Star Ultra'' was referred to as Bandana Dee, which Nintendo [[AscendedFanon made canon]] in ''Triple Deluxe''.
* NoExportForYou:
** One Kirby spin-off game called "Kaabii no kirakira kizzu" (Kirby's Super Star Stacker) for the SNES (Super Famicon in Japan) never got released outside of Japan due to being released there in 1998 '''two years''' after the Nintendo 64's release.
** For lesser-known reasons, the 20th anniversary compilation-game ''Dream Collection'' didn't get a Europe or Australian release.
* PermanentPlaceholder: Kirby was originally just programmed in to develop the game around him and come up with a character design later on, but then the developers began to grow attached to the [[WaddlingHead cute little blob]], and the design was decided as final.
* ShrugOfGod: The official word on whether Ado and Adeleine are the same character with two different names is "probably." The Japanese 20th anniversary booklet eventually revealed the two are different characters, but they're essentially the same except for their names.
* ThrowItIn: Kirby's appearance was originally intended to be a placeholder.
* TropeNamer: This series named the following tropes:
** AmericanKirbyIsHardcore
** BubblyClouds
** DreamLand
** MegatonPunch
* UrbanLegendOfZelda: No, despite what ''VideoGame/MushroomKingdomFusion'' may have told you, 02 and Dark Matter did ''not'' make any sort of "pact" with Drawcia. Nor is Dark Nebula 02 under another name. The latter theory has been officially {{Jossed}} by the Japanese 20th anniversary booklet (though it does state that Dark Nebula is part of the same species as Dark Matter). Meta Knight also wasn't possessed by anyone during the events of ''VideoGame/KirbySuperStar''.
** Funnily enough, some concept art later revealed Dark Matter (along with Nightmare) really ''was'' going to be in ''Canvas Curse'' albeit as a playable character rather than a boss, making it an ''enemy'' of Drawcia rather than an ally as the rumor claimed.
* WhatCouldHaveBeen:
** Some time during ''Kirby's Dream Land's'' development, Creator/ShigeruMiyamoto made the suggestion to Creator/MasahiroSakurai that Kirby be yellow instead of pink. Since Miyamoto had little, if any, involvement in the games' development (Kirby is developed by HAL Laboratory, while Miyamoto works for Nintendo's EAD division), this could have only have been a suggestion. However, to honor Miyamoto's suggestion, yellow Kirby is usually the [[ColorCodedMultiplayer 2nd player]] [[PaletteSwap palette swap]] for Kirby in his multiplayer appearances, including the ''VideoGame/SuperSmashBros'' series.
** [[http://www.youtube.com/watch?v=ILXkySK95po There was originally supposed to be a Kirby game for the [=GameCube=], but it never got released.]] According to [[http://www.nintendo.co.jp/wii/interview/sukj/vol1/index.html this interview]], there were ''three'' other unsuccessful attempts at making a home console ''Kirby'' game before ''VideoGame/KirbysReturnToDreamLand'', the fourth attempt that finally brought it out of DevelopmentHell.
** Unused sprites reveal that Kirby was going to have a shrinking ability in ''Kirby's Adventure'', but it was scrapped. The mechanic was later used in ''Kirby and the Amazing Mirror'' as the Mini ability. [[http://shmuplations.com/kirbysadventure/ An interview]] in the Japanese strategy guide for ''Adventure'' also revealed some other scrapped abilities: a rocket (implemented as Missile in ''Amazing Mirror''), an animal who could scratch and bite (implemented as Animal in ''Kirby Squeak Squad''), and creating blocks (which has never been used).
** ''''Kirby Air Ride'' was supposed to have a multi-themed star shaped track, but that got scrapped due to time constraints. It was also supposed to have a much bigger City Trial; the project was really ambitious even for its time.
** Prince Fluff was originally going to be the protagonist of ''Kirby's Epic Yarn''; the project wasn't turning out as well as planned, so Nintendo suggested adding Kirby.
** 'The artbook bundled with ''Kirby's Dream Collection'' includes unused character designs for some of the characters. Most notable is Meta Knight with red and black [[http://25.media.tumblr.com/tumblr_m7xuylJqjO1ra4czto1_500.jpg butterfly wings]], rather than his purple bat wings.
* TheWikiRule: [[http://wikirby.com/wiki/Main_Page WiKirby]], [[http://kirbysrainbowresort.net/ Kirby's Rainbow Resort]], and [[http://kirby.wikia.com/wiki/Kirby_Wiki Kirby Wikia]], although Rainbow Resort is mostly defunct as of late.
* {{Vaporware}}:
** Kirby, with the addition of a pink, curly hair on his head, was originally supposed to star in a SpinoffBabies game, ''Kid Kirby'', for the SNES; it was never finished, and all that remains of the game now are a few sprites and one stage layout.
** ''Air Ride'' began on the Nintendo 64 and was scheduled for a late 1996 release. It went through years of delays until it was quietly cancelled in 1998. It caught the public by surprise when a [=GameCube=] version was announced in 2003.
** When the Nintendo 64 was in development and still called the Ultra 64, one title in development was ''Kirby Bowl 64'' -- ''Kirby Bowl'' being the Japanese name for ''Kirby's Dream Course''. The snowboarding mode it featured likely led to ''Kirby's Air Ride'' as described above.
** Also, ''Kirby's Tilt 'n' Tumble 2'' for the [=GameCube=], using the UsefulNotes/GameBoyAdvance and cable to control the same way as the original title.
** There were several attempts to make a console Kirby game for the [[UsefulNotes/NintendoGameCube GameCube]] and later the UsefulNotes/{{Wii}}. The first of such attempts was shown in an E3 trailer, but this one fell through. The fourth attempt was finally released on the Wii as ''VideoGame/KirbysReturnToDreamLand''.
