You cant
You can't find a Vulpix in Pokemon FireRed version. That pokemon is version-exclusive to Pokemon LeafGreen.
ruby version isn't that were you get vulpix cach a vulpix yous the fire stone on it and you have a nine tales
Vulpix Eviee Thats it that I remember :)
Take a vulpix or growlithe to the old man at the top of cerulean city. You hav to show him a lickitung and an oddish first and he will give you a clue each time to find which Pokemon to show him. and eventually he will want to see the Pokemon that a fire type and if you find it and show it to him (growlithe or vulpix) he will gie you a fire stone.
Vulpix turns into a ninetales (kyuubi in japenese)
Vulpix is a pure Fire-type Pokemon.
Use a fire stone on vulpix?
Use a fire stone on Vulpix.
You use a fire stone on the vulpix
Yes.
Well you do need a fire stone, when you get a fire stone give it to your vulpix. after that go to that place where you evolve your Pokemon and your vulpix should evolve.
If you mean the old version, Pokemon Red, and not Pokemon Firered, then the only place that I can think of that have tons of fire Pokemon is the mansion on Cinnabar island. Go inside and walk around. You should find a lot of Ponyta and Vulpix, if you're playing Pokemon Blue, but if you're playing Pokemon Red, you'll more than likely find Ponyta and probably Growlithe. I'm not sure if you can find Vulpix in Pokemon Red or not. But, that's where you will find a lot of GOOD fire Pokemon. And, of course, Moltres is hidden away in Victory Road.
