The Pretty Petal Flower Shop in Pokémon Ruby and Sapphire was featured in the Pokémon Festa 2002 demo.
The map remains in the final release along with the NPC and her dialogue, which, despite being unused, was nonetheless translated in the English localizations.
I have to stay home today.
My big sisters had to go out.
They said it was for preparations.
In the autumn, we're going to start
a flower shop. Please wait for it!
It is still present in Pokémon Emerald but the NPC was removed.
