You can't. You have to get Pokemon SoulSilver if you would like the red orb or trade with a friend. The red orb is only obtainable in Pokemon SoulSilver.
In HeartGold you get a blue orb and in SoulSilver you get a red orb
No, you could only obtain the red orb in Pokemon Soulsilver and Blue Orb in HeartGold
You can only get red orb in Soulsilver.
You cannot get the Red Orb on HG, only on SS.
You cannot get the Red orb in Pokemon HeartGold. You can only obtain the blue orb. The red orb leads to Groudon and the blue to Kyogre. To get Groudon, you have to trade with someone to get it.
I dont think you can
You get the red orb after you defeat Red on top of Mt. Silver. Talk to Mr. Pokemon and he will promptly give you the orb.
you cant, you get red orb in soul silver & blue orb in heartgold from mr Pokemon after you defeat red at mt silver & after you get the kanto starteru cant it is only in soul silver but there might be a hack or action replay cheat heartgold has the blue orb for kyroger
You should go and head to Mr. Pokemon's Lab.
Mr.pokemon After defining red aka ash
You have to have a friend with Pokemon HeartGold who is willing to lend/trade the Blue Orb to you. In Pokemon SoulSilver, you will receive the Red Orb from Mr. Pokemon after defeating Red at the top of Mt. Silver.
(This is for both Heartgold and Soulsilver) You must beat Red at the top of Mt. Silver, then go to Mr. Pokemon's house (Between Violet City and Cherrygrove City) and he will give you the Blue orb/Red orb depending what game you have.
