I have tried to unlock the queen's door several times and i can't seem to get it open. I'm wearing the faerie hat and putting down flowers and going around the 3x3 area twice and it does'nt seem to open the door. Maybe I'm putting down the wqrong flower. My walkthrough says to put down a primrose. What does a primrose look like?
This one is a bit annoying. First, make sure you've dropped the flower on the correct square. If I remember correctly, it's one square in FRONT of her door (i.e. not right in front of the door, but one step back from it). I think this square is actually one of the ones in the 3x3 area that you need to walk around twice. As for which flower is the primrose, you can actually (kind of) check this by looking at your journal pages on items. There, you will see a name listed next to the picture of every item you've ever found, chronologically. You will have to painstakingly sort through all the pages of items until you find all the flowers so you can figure out which is which. I THINK it's the same flower that you use to enter the Faerie Realm in the first place, but I'm not sure.
Also, try going both directions around the 3x3 area. I think it might only trigger if you go in the correct direction.
Hope that helps!
