Sadly you cannot. which i think is odd since its called FIRE red. but anyways you will have to get a different Pokemon game such as Leaf Green and trade for it.
Vulpix is only available in leafgreen version.
You can't find a Vulpix in Pokemon FireRed version. That pokemon is version-exclusive to Pokemon LeafGreen.
Only leafgreen can get vulpix.
Use a fire stone on vulpix?
in the Pokemon mansion every one says you need leafgreen to find vulpix but you can find nintales even better than vulpix!
vulpix is sopposed to be everywhere in the Pokemon mansion but instead i caught a ditto but i want a vulpix its not fair!
There aren't growlithe in LeafGreen. FireRed has growlithe, LeafGreen has vulpix.
No you can only get it on leaf green
vulpix can only be found in leafgreen. u can trade to get 1, though.
Vulpix is unavailable in firered only leafgreen can capture vulpix.
where to find a vulpix on pokemon UNOVARPG
Only in LeafGreen not in FireRed. Sorry.
