Cabbage. Its four-year development was fundamentally enabled by the real-time clock and mass writability introduced in the requisite 64DD peripheral "such that even if the power is cut, [the game] can still raise the creature" and with optionally purchasable enhancement data. A subset of creature maintenance functionality is made portable on the Game Boy and can be synchronized back to the 64DD disk, via the Transfer Pak. It was expected for release in 1998 and then, in 2000, but all further development was distracted. In 2006, Miyamoto concluded: "It disappeared, didn't it ... However, the conversations and design techniques that popped up when we were making Cabbage are, of course, connected to Nintendogs and other things that we're doing now." The project which ultimately became Nintendogs began as a technical demo on the Nintendo GameCube long before it was considered for the DS. It was migrated to the DS when the handheld was still in development. Shigeru Miyamoto originally came up with the idea for the game when he and his family bought a dog, which inspired him to create the project. The game's producer, Hideki Konno, looking for a game to take full advantage of all of the Nintendo DS's features, decided on a dog simulation game. Nintendogs, first called Puppy Times, was originally designed to have fifteen different versions, one for each breed of dog. Satoru Iwata suggested this to convey the feel that the player was choosing a dog from a kennel. However, the debugging process for each version was deemed too time-consuming to be feasible. After going back and forth between several versions, they eventually settled on three, with six dogs each and the rest available after completing in-game goals. Merchandise In late 2005, Nintendo of America released the first series of Nintendogs "6-Card Fun Paks". Three different pack designs (each based on the US-released designs of the DS game) contains an assortment of "Collectible cards, stickers & more!". Each pack randomly contains two of 18 different Breed cards, one of nine different Dog in Training tip cards, one of six different Miscellaneous cards, one of 18 different Pop-Up Cards, one of six sundry sheets of stickers, one of four temporary tattoos and one Sweepstakes card. Another series of these cards were released in early 2007 by Enterplay, LLC. These cards, officially licensed by Nintendo, were created by the same individuals who worked on the first
