How do you catch Lugia in Pokemon HeartGold?

Answer 1

first you you save the power plant near lavender town and then go to diglett's cave and play the poke Flute on your radio to wake up the snorlax blocking the entrance to diglett's cave(the poke flute is the very top of the radio).then you must battle it,you can kill it or catch it (if you want to complete the pokedex then you should catch it)then go into the cave and you go north(upward in the game)and you'll end up in Pewter City.Then talk to the old man on a small hill,or platform with stairs and he will give you the silver wing.then you go to the whirl islands,go in the top right island and go on the top path and go through the maze(this maze shouldn't be too hard if followed everything correctly so far).There will be a guy blocking you,talk to him,show him the silver wing,then go all the way to the bottom(DO NOT go into other entrances,only the very BOTTOM) lugia will be waiting for you(he will be lv.70 so bring a strong pokemon)he is a psychic and flying type(hint:this only works in heartgold,but if you do the same thing in soulsilver,except the whirl islands part, you get the rainbow wing instead,lugia would be lv.45 and ho-oh will be lv.70 in soulsilver) does this help? =)
