The original presentation of The Wonderful World of Disney begins with a charming introductory scene set in the Magic Kingdom at Walt Disney World. Here, a curious little girl engages with iconic Disney Princesses like Snow White and Belle, inquiring about the enigmatic Princess Winnifred. The narrative seamlessly transitions as the girl encounters Carol Burnett, who generously begins to recount the tale of Princess Winnifred.
In a kingdom where the potential for marriage hinges on the decision of Prince Dauntless, a serious predicament unfolds. His mother, Queen Aggravain, upholds exceptionally high expectations for his future bride, asserting that only a "genuine" princess can meet her standards. After the latest hopeful fails to impress, Dauntless challenges Aggravain, suspecting her of intentionally thwarting his chances at love, to which she brazenly denies any wrongdoing. Meanwhile, as circumstances unfold, Lady Larken discovers herself in a delicate situation, pregnant, and feels the urgent need to secure a bride for Dauntless in order for herself and Sir Harry, the brave captain of the guard, to marry and avoid Larken’s banishment from the kingdom.
Weeks pass in a frantic search, until Sir Harry brings forth Winnifred, a spirited princess hailing from the murky swamps, who makes an unforgettable entrance by swimming across the moat to reach the castle. In stark contrast to Aggravain's disapproval, Dauntless is instantly smitten with her charm. With a mix of persuasion and determination, Dauntless convinces the reluctant Queen to grant Winnifred a chance. Consequently, the ladies of the court come to assist Winnifred in drying off as Aggravain consults with The Wizard to devise an elaborate test intended to reveal her true nobility. They decide on a challenge of sensitivity that involves placing a pea beneath twenty mattresses, confident that a true princess would never sleep soundly without feeling it.
As preparations commence, Winnifred is warmly greeted by King Sextimus, the actual ruler of the land who, due to a witch's curse, is rendered mute, alongside his clever Jester. The Jester elucidates Sextimus's misfortune, mentioning that only when "the mouse devours the hawk" will the curse be lifted. Enjoying a delightful croquet game, Dauntless is captivated by Winnifred's animated stories of her swamp life. As a ball is announced to honor Winnifred's arrival, Aggravain secretly plots to have the guests dance the tiring Spanish Panic, hoping to tire Winnifred out before the test.
In a moment of concern, Larken confronts Harry, revealing her fears that Winnifred may not withstand the test, urging him to assist her in cheating. Torn between loyalty to his duties and his love for Larken, Harry finds himself in a precarious position. At the ball, against all odds, Winnifred not only survives the demanding dance but suggests doing it again, infuriating Aggravain further. Dauntless, buoyed by his affection for Winnifred, professes his love, propelling events forward as he addresses the kingdom, sharing with them how unique and wonderful Winnifred truly is.
As preparations for the test intensify, the Wizard and castle staff secure twenty mattresses in Winnifred's chambers. Lady Larken, attempting to sneak away, is caught and imprisoned for the night to keep her silent. Meanwhile, Winnifred and Dauntless diligently prepare for an academic test they mistake for the next day. He bids her goodnight, leaving her to dream of a blissful future together. Dauntless seeks guidance from Sextimus regarding the prospect of becoming a father, only to receive advice expressed through gestures.
Navigating the castle, Winnifred finds Larken and aids in her escape from the dungeon, encouraging her to reconcile with Harry. Larken does find Harry, but their reunion is overshadowed when Harry confides in her of his plans to assist Winnifred. Simultaneously, the Wizard provides Aggravain with the tiniest pea in the realm, intending to orchestrate the test, while Sextimus overhears their scheming.
As night falls, Aggravain dreams of ruling forever and places the pea beneath the final mattress. In a twist, Winnifred, after being administered a soporific drink and lulled by an unexpected 'nightingale from Samarkand' (actually the Wizard in disguise), climbs into bed, only to be disrupted by an odd lump beneath her. Despite her tiredness, she tirelessly inspects the mattresses, growing weary and resorting to counting sheep to drift into sleep.
The next morning, as Aggravain smugly informs Dauntless of what she believes to be Winnifred's inevitable failure, the princess bursts in with a surprising declaration. She had not fallen asleep, recalling every sheep she counted. With excitement, Dauntless applauds her success, while Aggravain scrambles to conjure excuses to prevent the union. Boldly, Dauntless stands up to his mother, compelling her into silence and restoring Sextimus's ability to speak.
In a remarkable turn of events, the Jester, alongside others, grasps the truth of the curse, recognizing that it encompassed Aggravain all along. Now able to communicate, Sextimus reclaims his role as ruler. Meanwhile, Larken and Harry, eager to marry, unveil that Winnifred did not experience discomfort from the pea, provoking laughs as the Jester retrieves various medieval objects from beneath the mattresses. Dauntless leads Winnifred back to her room, intending for her to enjoy restful sleep once more. Despite her protests, she teases him that the pain she felt might hint she could indeed feel the pea, if only she had not been cheated. Ultimately, with the pea finally removed, she nestles into a peaceful slumber, and together, they all live happily ever after.
