From Shawn Slater of Disney Parks Blog:
In the newest Disney Fairies movie “Secret of the Wings,” coming to Blu-ray and DVD October 23, Tinker Bell journeys into the mysterious world of the Winter Woods, where curiosity and adventure lead her to an amazing discovery and reveal a magical secret that could change her world forever. In the Winter Woods, Tinker Bell meets Periwinkle, a frost fairy who turns out to be Tink’s sister, born of the same baby’s laugh.
Soon, you’ll be able to meet Periwinkle, too, as we bring a bit of the Winter Woods to Tinker Bell’s Magical Nook at Magic Kingdom Park and Pixie Hollow at Disneyland park. These areas will receive a sparkling layer of snow and ice, creating the perfect environment to greet Periwinkle and make her feel at home. Even Tinker Bell will be dressed for the occasion, wearing her warm, wintry ensemble from the film.
Look for Periwinkle to join her sister at Disneyland and Magic Kingdom parks, beginning in mid-September.
