冰雪奇缘：生日惊喜

"Frozen" will produce an extra short film, which will continue to be directed by the two directors of the movie version. The tentative title is "Frozen Fever." It tells the story of Anna's birthday arriving, with Elsa and Kristoff preparing to celebrate it grandly, but Elsa's ice and snow powers once again cause trouble. The hilarious duo, Olaf and Sven, will also make a splendid appearance, along with newly created songs.
