Seeds were not intended to be used in normal game play and therefore cannot be accessed without game enhancing devices such as Action Replay. These are used with special codes to add them to the player's inventory. When added to a player's inventory, they will take up whichever pocket they designate the seed to. Sometimes the seed will not appear as any kind of icon (meaning that while they are there, the pocket will look as if it were empty), but other times it will take the form of a leaf, much like furniture.
