The unused map and its single NPC
In Pokémon Ruby and Sapphire there is map data for a closed version of the Pretty Petal Flower Shop; which in the final version is usually always open on Route 104. In this unused map there is only one non-playable character who informs the player that the Flower Shop is closed.
The map was originally used in the Pokémon Festa 2002 demo, as to limit the player's experience of the game. It remains in Pokémon Emerald but the NPC was removed.
