It's said that when I want to open 3 cave of regis pokemon, I must have regigigas. I already catch regigigas lv1 in Snowpoint Temple (WITHOUT CHEAT, I catch it with ultra ball and I have to "sleep" it first), I know the cave, but it's empty. what do I do now?
Did you get the Regigigas from the eleventh movie event? It has to be that one specifically for the regis to appear.
