Hmm....I was able to beat Atlantica just before help was given, and then I moved onto Neverland. I locked the keyhole and went to Holloween Town. At this point, I'm trying to track down Oogie Boogie and entered the Evil Playroom. I was told by one of the Holloween Town characters, that I would never be able to find this "green door" and surely enough, I can't. Can someone give me some help with finding the "green door"?
