In a USA Today exclusive, Disney announced the creation of an all-new seven-minute Frozen short that's slated to hit theaters alongside their live action Cinderella remake.

With the announcement, Disney also released several stills from the short, which features Princess Anna (Kristen Bell), Princess Elsa (Idina Menzel), Kristoff (Jonathan Groff) and the snowman Olaf (Josh Gad).

Brought to the screen by original filmmakers Chris Buck and Jennifer Lee, the short follows Elsa as she struggles to plan a birthday bash for Anna while she balances her royal duties -- just before she comes down with a cold on the big day. "Elsa doesn't get a cold in the usual way," Lee explained. "She's special. Surprising things occur that wreak a little havoc."

The short includes a brand new song from husband-wife team Robert Lopez and Kristen Anderson-Lopez, who won an Oscar for Let It Go.

"We continue this story of these two sisters, who only had each other growing up together," says Gad. "They are still supporting each other. That's what this is about."

The short blows into theaters on March 13. You can read the full article on USA Today. Check out the rest of the stills below.
