i dont think you can i think you have to trade for it along with regice and registeel and if you do that then go to snowpoint temple(you must beat elite4 and cynthia)go through a few ice puzzles and at the bottom you will see a regigagis and if you dont have them then he will still be there but he will be asleep and unable to battle you so if you dont have them dont try going down there.
there is no regirock in Pokemon pearl,migrate please to get regirock
There is no way to send regice regirock and registeel from ranger to pearl. the only Pokemon that can be transferred from ranger to pearl is the manaphy egg.
No, you'll have to trade it from Platnium. Which in Platnium you find it in the Rock Peak Ruins.
It is in the Snowpoint temple, on the bottom floor, however I think you need an ice, rock and steel Pokemon first.
Regirock does not evove
You have to have regiice, registeel and regirock to be able to fight him
you cant unless you have a regigigas
the Pokemon are regirock, registeel, and regice and you would have to migrare from an other game to get them.. i feel like a Pokemon freak!! : D
you need regice, regirock, and registeel from Saphire/Ruby/Emeraled
You have to trade it with Diamond and Pearl.
its probably in another game you can do that
there is not regice in pearl. but if you have ruby, emerald, or sapphire you could trade regice,regirock, and registeel to get rigigious.
