Way up of Cherrygrove City.
The Red Orb you get at the Mr. Pokemon's House from the guy
He is the 2nd house North of Cherrygrove City, there is only one way to get to him and there is a Apricorn tree to the left of his house.
you have to first beat red aka ash ketum and then you go to mr Pokemons house and he will give it to you
Route 30.
Just go north of Cherrygrove City, and you'll come across his house.
If you beat trainer red go to Mr Pokemon's house and he will give you a red orb.
You can trade from Platinum to SoulSilver as soon as you have received the regional Dex from Professor Rowan in Pokémon Platinum and as soon as you have received the regional Dex from Professor Oak in Mr. Pokémon's House in Pokémon SoulSilver.
