u dont. just get the rainbow feather in pewter
you need a silver wing
It is Ho-Oh and you cannot catch it on a gameboy you need an emulator on a PC to catch it and even with that you need cheats.
you need to migrate it from one of those original games
If you want to catch lugia you need silver wing, tidal bell, beat all the kamino girls, complete all eight gyms
To catch Ho-oh you need a clear bell and the wing. For Lugia it's the silver wing and a tidel bell.
If you are referring to HeartGold and SoulSilver, then you need to acquire the Silver Wing, and the Tidal Bell, and visit the Whirlpool Islands. For SoulSilver, you need the Silver Wing and Tidal Bell, and the Kimono girls will dance, summoning the Legendary. This is your chance to catch it. For HeartGold, you should see Lugia ahead of you, ready to catch.
I forgot where, but you need to get the Rainbow wing, go to top of bell tower and SAVE before battle
When you get to Pewter city talk to a man outside and he will give you the rainbow wing. Then go back to bell tower.
To get ho-ho or lugia you will need to get the mystic ticket from the Pokemon events and take the ferry to navel island.
1 because you need to catch hoho/lugia but if you have action replay you can get 999x hope this was what you were looking for by dgamer297 :D
you need to obtain the Rainbow Wing from a person in Pewter City. Once you have it, you can go to the top of the Bell Tower and Ho-Oh will be there
you need the tidal bell and the silver wing
