What's the standard amount of times you can cross the dream bridge, five? I swear there have been times I crossed more than that (once I got over 1000 points in one day because of it). Next few times I play, I'll write down each area as I go to it and see how many times I get to cross total to see if this is true.
Dream World really sucked for me today. The only female Pokemon I got was a Glameow (I know I said I won't play the minigames if I don't want the Poke, but I will always play if it's a Poke I haven't encountered before). :/ I didn't even get any males with useful moves.
