lvl 39 - you'll see a blue sphere across the road from you. unfortunately, there's a ghost waiting for you on the left side of the alley as you exit the alley. Let the ghost carry you back, then hop along behind the ghost, and stay directly on their left, just out of sight. Keep hopping until you get past them, and then you should be able to cross the street. Don't wear shoes.
lvl 42 - once you get to your feet, go outside. let the gold ghost catch you. they will blindfold you, pay attention to where they drop their sphere. when you touch their sphere, it takes off the blindfold and the leg bindings. take the gag off, and call for help to see where the other spheres are. the gold ghost is a massive pita, though. she flies all around the map, and if she catches you, she will drop you in the very same spot over and over again. the blue ghost guarding the alleyway with the final sphere will also drop you in the same spot, all the way across the map.
