First look": "Frozen" returns in new "Frozen Fever" short film

Anna, Elsa, Olaf and the rest of the Arendelle gang are heading back to theaters next month, and now we're getting a new look at what they're up to now in "Frozen Fever."

The animated short film, which will screen ahead of Disney's live-action "Cinderella" starting March 13, has Elsa planning a birthday party for her sister. And Olaf, not surprisingly, seems to like cake as much as he likes warm hugs.

"Frozen Fever" will also feature a new song written by Robert Lopez and Kristen Anderson-Lopez, the duo who won an Oscar for "Let It Go."
