Mark Twain and Satan

The Mysterious Stranger is the final novel attempted by the American author Mark Twain. It was worked on periodically from roughly 1890 up until 1910. The body of work is a serious social commentary by Twain addressing his ideas of the Moral Sense and the "damned human race".
A scene about this story also appears in the 1985 claymation film The Adventures of Mark Twain, where Satan gets Tom Sawyer, Huck Finn and Becky Thatcher to construct small clay people to bring to life and live in a small kingdom together before Satan destroys them through fighting, plagues and natural disasters, depicting the futility of mankind. The scene also quotes Satan's last line from the book. In this version, Satan appears playful and friendly when he constructs the small kingdom, slowly revealing himself as cruel and hateful as he destroys it. He appears as a robed noble, with a mask where his head would be. As his cruel nature is revealed, the mask changes from appearing kind to demonic, and finally to a grinning skull.
