The popular musical that marked the Broadway debut of Carol Burnett. Based on "The Princess and the Pea" by Hans Christian Andersen.
Story:
Princess Winnifred arrives at Prince Dauntless the Drab's castle hoping for the hand of the prince. His mother, Queen Agravain, insists that her son can only marry a princess of true blood (one who can feel a pea that is underneath a pile of mattresses). Winifred passes the test, unable to sleep all night from discomfort and they live happily ever after.
