The short and its song were first announced on September 2, 2014 during ABC's one-hour special The Story of Frozen: Making a Disney Animated Classic. Variety announced on the same day that the short's release would be in spring 2015 under the title "Frozen Fever", along with Lee and Buck coming back as directors, Peter Del Vecho returning as the producer, and Robert Lopez and Kristen Anderson-Lopez writing the song. The short's summary is as follows: "...it's Anna's birthday and 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." Olaf, the snowman, also will make an appearance in the toon. In a mid-October interview, Idina Menzel revealed that the cast had already recorded their vocal tracks: "We just worked on a short for Frozen." On December 3, 2014, it was announced that Aimee Scribner will be a co-producer and that Frozen Fever will debut in theaters with Disney's live-action Cinderella film on March 13, 2015. In late December, the directors told the Associated Press: "There is something magic about these characters and this cast and this music. Hopefully, the audiences will enjoy the short we're doing, but we felt it again. It was really fun."
