Good news for Frozen fans. Disney is releasing an all-new short called 'Frozen Fever.' Anna, Elsa, Kristoff and Olaf are all back and on the big screen. 'Frozen Fever' will debut in theaters on March 13, 2015, right before Disney’s new live-action ‘Cinderella.’

The new short will focus around Anna’s birthday, which Elsa and Kristoff are determined to celebrate until Elsa’s crystallizing powers threaten to ruin things. The short will also feature a new original song from the same team that brought you "Let it Go" sung by Idina Menzel.

Frozen is the biggest animated feature of all time, grossing  $1.219 billion worldwide.

Are you looking forward to 'Frozen Fever' when it hits the big screen in March?
