I suspect a game bug but perhaps I missed something. I knock on the door and I hear the doctor and also some other guy complaining about his eye. I have the glass breaker..the weather vane, the unbreakable bottle, the bird, the locket, the flower pot nose, the cheese, the flyer, the deep gut map and the you tube. I have been trying not to use any walkthroughs or hints but I am totally stumped. The note on the doctors door says he is busy and after I knock and hear the guy complain about his eye Guy Brush just says he will come back later. I've put the bottle in the cannon and shot it ...not sure what else to do. I have traced my steps to the point I am at via a walthrough...no luck.
Thanks in advance for any help!
