How Can I Get a Dragon Scale on "SoulSilver"?

Some Pokemon can only evolve through the use of an evolutionary item. There are 20 such items In "Pokemon SoulSilver," including the Dragon Scale. The Dragon Scale is a thick and rare item that evolves Seadra into Kingdra. If you trade a Seadra while it is holding this item, it will evolve into Kingdra immediately. The Dragon Scale is found in Mount Mortar or at the Pokeathlon Dome.

Fly to Ecruteak City and go east to Route 42. Walk east on Route 42 until you reach a small body of water. Use the "Surf" ability to cross the water to Mount Mortar. Enter Mount Mortar through the cave entrance.

Surf west instead of taking the descending ladder. Ascend the waterfall with the HM07 ability. Surf around the land and go through the cave entrance. Go to the northwest corner of the cave. Head east of the ladder and pick up the Item Ball, which holds the Dragon Scale.
