The Old Man of the Mountain is the titular antagonist of the 1933 Betty Boop cartoon "The Old Man of the Mountain" and like many Betty Boop cartoons the story was told mostly via song and fantastical imagery.
The Old Man of the Mountain was a gigantic and unkempt being who lived deep in a mountain cave and terrorized everyone around him, except for Betty Boop - who decided to confront the Old Man.
Upon meeting the pair engage in a sequence of song and dance but the Old Man of the Mountain shows unwanted advances, to the point of trying to force himself on Betty - who flees but is pursued mercilessly by the giant until the woodland animals rebel against the Old Man and subdue him before beating him as punishment for his unruly behavior.
