Where do you find a moon stone in Pokemon soul silver?

Answer 1

You can buy Moon Stones in the Pokeathlon Dome on certain days.

You can also find them on the pokewalker on the Volcano Path route (post National Pokedex and requires 10,000 watts to unlock) and Night Sky's Edge, the route unlocked by the GameStop Jirachi.

If you let your mom save some of your money, she may send them to you periodically.

In the same rooms where you have to complete a picture puzzle of Kabuto, Aerodactyl, Ho-Oh, or Omanyte, there is a plaque that has a word that is spelled using Unowns. Complete the following steps to get the hidden items:

Room with the Kabuto Puzzle: The word is "Escape". You must use an Escape Rope while facing the plaque. You can easily get an Escape Rope at the Violet City Pokemart. The four items you receive are Energy Powder, Heal Powder, Oran Berry, and Pecha Berry.

Room with the Aerodactyl Puzzle (accessible by Surfing): The word is "Light". Use Flash while facing the plaque. The four items you receive are Energy Root, Heal Powder, Moon Stone, and Sitrus Berry.

In Pokemon HeartGold, Ho-Oh is obtained in the Bell Tower. In Pokemon SoulSilver, Ho-Oh is obtained after you have defeated the Elite Four.

Room with the Omanyte Puzzle: The word is "Water". You must have a Water Stone in your bag. The items you receive are Leppa Berry, Mystic Water, Stardust, and Star Piece. You can get a Water Stone by winning it at the Pokeathlon on Wednesday.
