You can get it in Pokemon Black and White if you send a special Celebi from Pokemon Heartgold, Soulsilver, Pokemon Platinum, etc.
If you have two Nintendo D.S.es, Put Guardian Signs in one and Platinum in the other. On Platinum, go to Mystery Gift, and hit Recieve from a Friend. On Ranger, Go to Ranger Net, Send a Pokemon, Hit the Pokemon you want to send, and send. Both D.S.es must be nearby. THis works with Diamond, Pearl, HeartGold, and SoulSilver as well. Each Pokemon can be sent only once.
To get Squirtle you can either trade it over from Heartgold/Soulsilver after beating Red, and talking to Proffesor Oak. Or you can send it to pal park from Pokemon Firered/Leafgreen. Otherwise you can't.
You can't Get HootHoot in Pokemon White Or Black you Just Have to use the Poketransfer and you have to send your hoothoot from your Diamond, Pearl, Platinum, HeartGold, or SoulSilver if you have in there
You can't send the Pokemon directly from Pokemon Emerald to Pokemon Heart Gold but you can migrate your Pokemon from Emerald to Pokemon Pearl, Platinum, Diamond and then trade it to your game Pokemon Heart Gold as long as you have a friend with a DS(Dsi)
bye going to platinum Pokemon center and and press send
yes
You can't, you must send it over from Pokemon Ranger.
you choose the Pokemon you are going to send from ranger and click send you then at the same time heartgold has to be on mystery gift searching for gifts from firiends
You cannot. Once in Black/White it cannot be sent back
Nope, there is no way to trade or transfer Pokémon from Pokémon Gold over to Pokémon HeartGold. The DS games are not compatible with the original Gameboy and Gameboy Color games.
Buy mail then attach it to your Pokemon write whatever then trade that Pokemon to a friend they can read it then send it to there PC.
