History Trivia / KirbysAdventure

** When Sakurai's higher-ups originally gave the greenlight for the game, they initially intended for it to be a straight port of ''Kirby's Dream Land'' to the NES as a quick cash grab to avoid bankruptcy -- HAL was still hurting from the commercial failure of ''Metal Slader Glory''.

** The Hal Room remains intact in the remake, however, unlike the NES original, it is inaccessible and can only be accessed through codes.
** Several leftover sprites in the game's rom feature a [[https://tcrf.net/images/6/60/Kirby%27sAdventureMini.png tiny Kirby]], which is a leftover from an unused shrinking ability.

** [[DummiedOut Some sprites in the game's ROM]] suggest a shrinking ability would debut in ''Adventure'', which was confirmed as in [[http://shmuplations.com/kirbysadventure/ an interview in the Japanese player's guide]]. This ability would be used in ''VideoGame/KirbyAndTheAmazingMirror'' as Mini, though without the ability to slide.

** In [[https://youtu.be/khJa2vIW0xY an episode]] of ''Masahiro Sakurai on Creating Games'', Sakurai showed off a few design documents he whipped up during development of ''Kirby's Adventure''. Some of these include the ability for Kirby to generate his own blocks and a "trap" ability that causes Kirby to self-destruct, neither of which made it to the final product. Sakurai also considered removing Kirby's flight, but ultimately settled on {{nerf}}ing flight by decreasing air speed and screen real-estate.

* RefittedForSequel: Two scrapped ideas the dev team had for copy abilities were a "Mini" ability that could shrink to squeeze into tight gaps and an "Animal" ability that could scratch and bite at enemies. These abilities were eventually realized in ''VideoGame/KirbyAndTheAmazingMirror'' and ''VideoGame/KirbySqueakSquad'', respectively. Another ability let Kirby ride around on a rocket, which was realized in ''Amazing Mirror'' by letting Kirby ''become'' a rocket when he gets the Missile ability.

** The remake had different sprites for several enemies, including Waddle Dees with more spread out faces, Pengy using the design from ''Adventure'' and Poppy Bros. Sr. using the design from ''VideoGame/KirbySuperStar''.

** Level 2 of Rainbow Resort features a BossRush of Mid-Bosses, and it features a secret passage that grants you access to stronger versions of the boss fights, but skips to the fight with Bonkers. Unused rooms show that there is stronger version data of the missing mid-bosses.
