Dōbutsu no Mori e+ is the only version of the original Animal Crossing to not be packaged with a promotional memory card (even the N64 Dōbutsu no Mori included a themed Controller Pak). This is because the game's extra content expands the maximum file size to 72 blocks: 57 for town data, 5 for saved letters at the post office, 5 for saved patterns at Able Sisters, 1 for NES save data, and 4 for travel data. While GameCube memory cards were officially available in larger 251-block and 1019-block sizes, all first-party cards bundled with games were manufactured exclusively in the minimum 59-block size.
