What happens when you complete the browser on Pokemon Ranger 2?

I think you're supposed to go to the old lady(I don't remember her name because I don't

have the game anymore)and talk to her,then I think she'll give you info about Regigigas and tell you that you need to catch it or something.But I do know that Regigigas is the

hardest boss in the game and it is located under that quicksand-like pit in the Hippowdon

Cave(I'm not remembering if it was Hippowdon "Cave",but anyway you know where I'm talking about.)
