its pretty hard to explain, but. ill try my best. first you need to get the 7th gym badge. than you get the hmDIVE from steven. than you teach that move to one your Pokemon and you swim around the sea near mossdeep. when you go under. theres going to be like a darker marking on the floor. you go next to it and press a thann you'll most likely find something. you need to get yellow shard for thunder stone red shard for res stone and blue shard for waterstone. they only have three. when you get the one you wanted, when you look for the treasure hunter. his house is located on the ocean. its near mossdeep. well GOOD LUCK .
you can also get red shard
or...
you could just go to new mauville and get it there its all the way in the back where the generator is at or trade from firered or leaf green but you will rather do it my way or the yellow shard way its your choice.
you can also find green shard for leafstone
You can trade a Yellow Shard at Hunter's house for a Thunderstone.You can also get one in New Mauville,but you'll need the Basement Key to unlock it.
You get one in New Mauville, it's close to the end.
you go underground and dig for it
In Generation III (Ruby, Sapphire, Emerald, Fire Red, Leaf Green), the only Pokemon that evolve with a Thunderstone are: Eevee, which evolves into Jolteon; and Pikachu, which evolves into Raichu.
Pikachu doesn't evolve by level, you have to evolve him with a thunderstone.
I don't have Gold version, but I think you mean Jolteon and you use a thunderstone on Evee. If there are no thunderstones in Gold then I don't know.
Celadon city
You give it a thunderstone
Pikachu+Thunderstone=Raichu Eevee+Thunderstone=Jolteon These are the only 2 pokemon that evolve with the thunderstone in pokemon emerald
to evolve Pokemon
No Level; Use Thunderstone
Maybe.
Pikachu can evolve into a Raichu.
Of course it can. just use a thunderstone. i dont remember where it is, though.
I found one on route 120, and used to thunderstone to get a jolteon from it.
you must find sharps in sea bottom and trade in hunter's for a thunderstone
Pikachu evolves by using a thunderstone, so technically he can evolve at any level.
I believe it's only Evee-Jolteon and Pikachu-Riachu.
you have to level it up with a good level of happiness thunderstone works in a different game
You need surf, you'll find on at New Mauville (the route is under the cycle bridge to the east) There'll be a thunder stone in the complex. You can also collect Yellow Shards from using Dive in the Ocean and trade them for a Thunderstone. Otherwise you can simply trade with FireRed/LeafGreen with a Pokemon holding a Thunderstone.
