First find a Red shard underwater you can find dive spots that lead to red shards near the hunters house which is west from mossdeep city trade the red shard to the hunter to get a fire stone.
a vulpix will evolve with that stone
vulpix evolves with a firestone into ninetails. vulpix can be found at Mt. pyre
in the fiery cave. next to the tram
You can find a Fire Stone in the Fiery Path after you get the HM for Strength.
You can get it at fiery path but you must have strength(TM04).It is right next to the cable car.
No one
find one in the firey path or trade 1 red shard for one at the hunter's house
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.
u gotta find a red shard & give it to Hunter to the left of mossdeep city. He lives on an island with one house on it.
an eevee
Vulpix.
There is a person on an island just above Mossdeep who will trade colored shards for evolution stones. (red-firestone, yellow-thunderstone, ect)
