I need help restoring the skulls in the Library of Lonesome Manor. I have restored the skull in the floor and the one in the revolving wall, but am having trouble restoring the last skull.
It's the skull that you restore by painting it through a small hole in a bookcase that moves back and forth. I try aiming through the hole, but it doesn't seem to work. How do I restore this skull? Please help me. Thank you.
