If the prospect of a new live-action version of Cinderella wasn’t enticing enough, the new Disney film is opening with a special added attraction: “Frozen Fever,” a short sequel to Frozen, the most popular movie (and most dastardly earworm) of 2013. And here I thought “Frozen fever” was a mental illness that made kids sing “Let It Go” over and over again until their parents begged for the sweet release of death. My mistake.

Above, you’ll see the first brief trailer for the short (so don’t expect much, because the short’s already short to begin with). Here’s the official synopsis for the film, which debuts in theaters before Cinderella on March 13:

In ‘Frozen Fever,’ it’s Anna’s birthday and Elsa and Kristoff are determined to give her the best celebration ever, but when Elsa catches a cold, her powers may put more than just the party at risk.

“Frozen Fever” is directed by Chris Buck and Jennifer Lee, the same filmmakers behind the original Frozen, and features returning cast members Kristen Bell, Idina Menzel, Jonathan Groff, and Josh Gad as everyone’s favorite living snowman Olaf. It should be a fun time. Unless you too have contacted Frozen fever, in which case you need to seek immediate medical attention.
