How do you catch a shiny Groudon in soul silver?

Answer 1

(must beat ash/red first) First, you get all 16 badges from johto and kanto then you go to copycats house she'll say she lost her doll. Go to vermilion city go to the furthest house to the left /fanclub and talk to fat guy for the doll. Return the doll to copycat then you go talk to steven at saffron city's train stationhe gives you 3 stones to pick each holds a Pokemon. After you choose 1 go to prof oak he'll give you bulbasaur charmander or squirttle after you pick one, go to mr.Pokemon he'll give you red orb (Soulsilver) blue orb (Heartgold) than you fly to cianwood city in johto you surf to emmeheded tower you go straight in and you'll see Groudon (Soulsilver) Kyogre (Heartgold) Hope this helped :)

congrats, you are 80% correct, except that its game-red, not manga red, not ash. red is NOT IN ANYWAY ASH. just pointing it out. and you don't need to get the magnet pass. just beat both champs(elite 4 and champ once, red once) and then get one starter from oak. go to mr Pokemon's house and he'll give you the orb. also, get both games hg and ss to get both kyogre and groudon, then tak to mr Pokemon and he'll give you a third orb, wich going back to embedded tower, makes rayquaza appear. good luck catching all 3 o'em!
