Mysterious Mose (1930) More at IMDbPro »

This cartoon, Max Fleischer's Mysterious Mose, was one of the early ones that starred a girl voiced by Mae Questel who would be eventually known as Betty Boop, here drawn with dog ears. She's all alone in bed at night and scared because she finds a human bulge in her blanket and literally has her shirt float out of her twice! (though we don't see her naked body!) She then sings the title song as her head pops forward and back. That's before we see who the stranger is. It's Bimbo, the one who's actually credited above the title here. Then he sings the song as all sorts of surreal morphing come about...A little atmospheric in the beginning with some good humor provided before the surreal musical finish makes this one of the more entertaining of the early sound Fleischer cartoons. This one is well worth a look for animation buffs.
