We haven’t seen the Frozen gang since the movie became a global phenomenon in 2013. Now they’re back! Here’s a first look at “Frozen Fever,” a new animated short that’ll premiere before the live-action Cinderella on March 13. This time, Elsa, Anna, and Olaf return for more shenanigans when Elsa catches an icy cold that wreaks havoc on Anna’s birthday celebrations. And, once again, Olaf’s the scene-stealer.
