this is how but might not be what your looking for!
1.open soul silver and have a friend with diamond or pearl
2.trade magnaton to diamon or pearl
3.get him/her to lv up the magnaton in mount cornet
4.it should evolve then trade back
Magneton can NOT evolve in the Johto region because it needs a certain magnetic field in Mt. Cornet (Sinnoh region).
You can trade from Diamond, pearl, and Platinum to get Magnezone.
== == == == At level 40 it evolves into Rapidashi think you have to get it to level 40
Arbok can not evolve into any other Pokemon. Hope this helps.
level 55
Unfortunately, as there is no Moss Rock in either Johto or Kanto, it is not possible to evolve Eevee into Leafeon through normal means in SoulSilver Version. The only way to do so is to trade the Eevee to Diamond, Pearl, or Platinum Versions, level it up in Eterna Forest, then trade it back to SoulSilver.
Somewhere in the 30's. Anyone who says 30 is wrong, because i have a level 32 pidgeotto that iraised from level 4. Do not expect an evolution until at LEAST level 33. Also, if anyone knows for sure, feel free to edit.
graveler doesnt evolve at a level, you evolve it by trading.
