trade it over from diamond/pearl/platinum
You can buy one at pokeathlon.
Use a thunder stone
it's the thunder stone and at the pokeathon on wednesdays for 2000 or 2500 bp
2500 points
Fly to National park then just go into the pokeathlon Dome .And play games their and get points cash the points in for a thunder stone and much more.
the pokeathlon and some other places i think hopfully this helped :D
Buy it with points at the Poke League thing just off of National Park
yes,you need to get 3000 points in the pokeathleon dome you can also get thunder and shiny stones there
The best place for me is the pokeathlon prize exchange booth. A thunder stone won't always be there, but it will be there almost every day of the week. The pokeathlon is located north of goldenrod city, in the Johto region. Hope I helped!
thunder stone, water stone, and fire stone just like in every other game... But if you want Umbreon or Espeon they evolve with love Umbreon(night), Espion(day)
the Pokemon that evolve with the help of a thunder stone are : pikachu +thunder stone = raichu, or eevee + thunder stone = jolteon.
