How do you get the coin case in Pokemon flora sky?

It seems you're asking about a Pokemon game called "Flora Sky." However, there's no officially released Pokemon game with that name.

Could you be thinking of a different game or a fan-made project? If you could give me more details, I might be able to help you find information on how to obtain a coin case in the game you're playing.

For example, you could tell me:

* The full name of the game.

* What platform you're playing it on.

* Any other details about the game, like if it's a ROM hack or a fan-made project.

Once I have more information, I'll be happy to help you find the coin case. 😊
