Haunted Tower Floor 2[]
I thought I had this figured out but when I went back the second time it didn't work. You have to hit the wheels to get rid of the skulls to walk through for the pants and to get to Floor 3. The first time, I walked up the screen and hit the first wheel twice, and the second wheel once. I was then able to walk up the first row and get the pants. Then I walked up and hit the first wheel once, second wheel once, third wheel once, and fourth wheel once. Then I walked across the screen and hit the fourth wheel 9 times. I was then able to walk up the last row to get to the door for Floor 3.
