this ultimately leads me to the mushroom isle where there are no enemies or really anything at all. now i'm supposed to go back to the room which you must be invisible to enter but there doesn't seem to be anything to do there either. no enemies for sure. what am i missing?
Is there anything that's supposed to happen after that? I took a stroll with what's-her-name and we just fought zombies over and over, and nothing else seemed to happen.
