Pokemon Crysta: Firestone?

Question

Where do you get a firestone? I need it for Growlithe.

Answer 1

You'll need to be in Kanto and go to bills house. Give him a Pichu and he'll give you a thunderstone. He'll ask for either a vulpix or growlithe, show it to him and he'll give you a fire stone. (this is the only way to get it in crystal)
