Elsa, Anna, Kristoff and Olaf Reunites with Fans in Walt Disney's ‘Frozen Fever’

Queen Elsa, her sister Princess Anna, the iceman Kristoff and the snowman Olaf will be returning to the big-screen in a seven-minute featurette that will debut in theaters together with Walt Disney Pictures' Cinderella on March 13. Titled Frozen Fever, the short animated film will be a sequel to 2013's critically acclaimed and commercially successful Frozen.

According to the studio's teaser, "on Anna's birthday, Elsa and Kristoff are determined to give her the best celebration ever, but Elsa's icy powers may put more than just the party at risk." Elsa catches a head cold the same day as the party and it creates a major threat to the celebration. The first-look teaser clip for Frozen Fever was released to media and the Internet on Wednesday. In the clip, Elsa is seen in a new party dress, a brightly colored green floral frock for the birthday party, while Anna is shown in a tulle-accented gown but still in keeping with the basic design of the dress she was using in Frozen. Directed by Chris Buck and Jennifer Lee, the short animated film once more stars Kristen Bell as Anna, Idina Menzel as Elsa, Jonathan Groff as Kristoff and Josh Gad as Olaf.

The sneak peak Frozen Fever video also previews a new song, titled "Perfect Day," that may be as "addictive" as Frozen's "Let It Go." Groff (who voices for Kristoff) told The Wrap that the new song "will be stuck in your head as much as 'Let It Go.'" As observed by the entertainment news site, Idina Menzel's rendition of the addictive hit won the 2014 Academy Award for Best Original Song and became an obsession among children around the world. As with "Let It Go," the Oscar winning songwriters and real life couple Robert and Kristen Lopez are also responsible for creating the new song for Frozen Fever.
