I got the 4th badge, now I dont know what to do... I've been stuck for like 2 days, i've talked to pretty much everybody i could, but I still can't get either past those stupid Psyducks, the dude doesn't let me go to that sunshine city because of the blackout, and I cant use strength to get through that one cave
Just go back to Hearthome City. You can now challenge the gym leader there (Fantina, whom you first met in front of the contest hall) for the fifth badge.
Edit: Do this after Celestic town.
I tihnk you have to go up to that house beside the Psyducks then go right. I think there's a path there.
T'll check and get back to you on that.
nevermind I Just checked a walkthrough and apparently I had to talk to a galactic grunt in pastoria...
That's only a cafe cabin for pokemon battles. Go east of Pastoria City (Where you get the fourth badge) and travel on route 213 until you meet Cynthia, who will give you a secret potion in order to move the Psyduck. Go north from there to route 214, then finally north from there to Celestic town. You will meet Cynthia's grandmother there and she will give you surf. After she gives it to you, return to Hearthome.
