with a fire stone.
vulpix,growlite and evee
In Pokemon LeafGreen, to get a Ninetails, you must first capture a Vulpix. Vulpix can be found on Routes 7 and 8, and in the Pokemon Mansion. Once you have obtained a Vulpix, a Fire Stone is needed to evolve it into a Ninetails.
Once you have a vulpix from leafgreen use a fire stone on it to evolve it to ninetails.
You can't evolve Vulpix into a Ninetales. You will need a FireStone. You can get one of those at the Big Department Store at Celadon City. Good Luck!!
Vulpix evolves into Ninetales. This is the only Pokemon caught in Emerald that can evolve from a firestone. If you have traded an Eevee or a Growlithe to your Emerald game, they can evolve too.
In FireRed and LeafGreen, the pokemon that evolve via the firestone are as follows: Eevee (into Flareon) Growlith (into Arcanine) Vulpix (into Ninetails)
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.
Vulpix is only available in leafgreen version.
There aren't growlithe in LeafGreen. FireRed has growlithe, LeafGreen has vulpix.
Use a fire stone on Vulpix.
You use a fire stone on the vulpix
You can't find a Vulpix in Pokemon FireRed version. That pokemon is version-exclusive to Pokemon LeafGreen.
