I played this when I was in my 20s. I completed the game with thanks to my wife who helped me complete some of the many puzzles in this game. This image is from a cut scene where Klayman (klaymen?) finds this music box and starts to play it. What happens next? Talk about getting something unexpected for Christmas ;)

Is anyone else familiar with this game, The Neverhood? It only ran on Windows 98.
