Densetsu no Starfy (GBC)
Densetsu no Starfy for the Game Boy, and later for the Game Boy Color was a tentative Starfy title which was eventually canceled, though it was eventually released in the form of Densetsu no Starfy for the Game Boy Advance on September 6, 2002. Any initial plans of releasing Densetsu no Starfy for the Game Boy Color were abandoned in anticipation of the release of the Game Boy Advance.
Planning on this game began as early as November 1995, for the original Game Boy when Nintendo producer Hitoshi Yamagami was asked by his boss to come up with some kind of 'floaty platformer', which originally featured a balloon.  Hitoshi Yamagami received a directive from his boss to make it but had difficulties on having the balloon move where it was intended to. According to Hitoshi Yamagami, it turned out to be an "annoying game that wasn't any fun at all". Hitoshi Yamagami asked his boss if he could operate the balloon itself and he approved his request.
In a 2009 conference call between Nintendo Life and six developers of The Legendary Starfy, Hitoshi Yamagami states that he worked on the idea of a floating character being pushed through a maze for six months. It is unclear whether he is referring to the balloon or not.
Hitoshi Yamagami would later collaborate with TOSE producer Yasuhiro Minamimoto. Hitoshi Yamagami talked about the the game with Yasuhiro Minamimoto and they came up with the idea of changing the balloon into a bubble with a Nintendo character in it but Hitoshi states in Nintendo Power that this "wasn't a very practical setup".  Later, Hitoshi asked if they could take control of the floating character, rather than just moving it around. Hitoshi and Yasuhiro both decided that using a water based character would be a good idea, as long as that character fit the environment. Both a jellyfish and a starfish were initial considerations, and a starfish, was eventually chosen for this game. Development on this game continued through 1998 and as such, Nintendo encouraged TOSE to rework this game for the Game Boy Color. In 2000, the Game Boy Color version underwent a period of promotion, where details about the game began to surface on the official Japanese Nintendo website. A trailer of the game was presented in 2000's Nintendo World event, amongst highly anticipated titles such as Luigi's Mansion and Super Mario 128.
As the game was approaching its release for the Game Boy Color, it was again canceled and rebuilt for the Game Boy Advance which was only going to be released in 2001. Starfy was apparently going to be purely a starfish, until he was made to fall down from the sky, which supposedly invoked a community policy for TOSE to reply that Starfy is neither a star or a starfish when asked.
There are various differences between the Game Boy Color version and the final Game Boy Advance version still noticeable on Nintendo of Japan's page about the trial demo. For example, the official logo and some of the character artwork and names of characters were changed later in development, including Kyorosuke (Moe) who was originally known as "Kyororon". It should be noted however that the Nintendo Space World 2001 trial demo for the Game Boy Advance was promoted with the old logo used during the Game Boy Color period. There was also character artwork for the Game Boy Advance version from early in development, which although different (with the exception of Moe), were not final.

Although the Game Boy Color game was canceled, a trailer of the game (right) is still available as a QuickTime movie on the official Japanese Nintendo website. At least one remaining clip of the game from the Nintendo Space World 2000 event also exists on the Internet.
