How do you get the Rainbow Shard in Pokemon HeartGold?

Answer 1

u need to save the radio tower from an invasion of team rocket! once that mission comes up on your game! then the owner of the radio tower will give you it... in order to enter the tower u need to be wearing a team rocket uniform and in order to do that u need to go in the underground tunnels in golden rode city and ask the only guy in there to take ur pic and then he will let u keep the uniform... and then when he gives u a golden wing he will say that u need another item to get HO-OH and that other item is the bell thing u get that by going to black thorn city! and beating the gym leader... after that i think prof. Elm will call u or something like that i rlly cant remember and then he will tell u to go to the dancing theater in the town wear the bell tower is. When inside the theater you will see 5 or 6 Chinese ppl and 1nc u beat them they will give u the bell and they will head off to the bell tower then u have to go to the top of the bell tower and u will see them dancing and then HO-OH will arrive!
