Rapunzel is the protagonist of Disney's 2010 animated feature film, Tangled. She is the princess of Corona, known for her long, magical, golden hair. As a child, Rapunzel was abducted by a wicked crone and locked away in a remote tower for eighteen years—in during which, she became fascinated with a phenomenon involving "floating lights" that only appear on her birthday. With the aid of the handsome thief, Flynn Rider, Rapunzel escaped her tower to learn more about the lights and pursue her dream of exploring the outside world.
