the rainbow wing is your key into the bell tower. you just walk in and as you talk to the monk blocking your way, it will hover above your head and he will let you through. go through the tower until you get to the roof. the kimono girls will summon ho-oh with the help of your clear bell (if your playing soulsilver and beat the elite 4, you don't need a clear bell) in heartgold ho-oh is level 45, in soulsilver he's level 70, but you can only catch him once you've reached kanto and gotten the rainbow wing. (same for catching lugia in heartgold)
