How do you attach flash machine on Pokemon tower defense?

It seems you're asking about a specific feature within a game, but you haven't specified which Pokemon Tower Defense game you're referring to. Could you please provide more context?

For example, tell me:

* The name of the Pokemon Tower Defense game: Is it a mobile game, a browser game, or something else?

* What platform are you playing on? (e.g., Android, iOS, PC)

Once I have more information, I can try to help you figure out how to attach a flash machine or any other specific feature within the game.
