Frozen fans, fear not: a follow-up is forthcoming, and Disney has unveiled new images from Frozen Fever, the short film set to follow in the original's icy footsteps.

Original Frozen directors Chris Buck and Jennifer Lee are returning to direct the short, reports the Los Angeles Times, which also released five new images and a video from the short. Anna, Elsa, Kristoff, Sven, and Olaf are back in the seven-minute adventure which follows the group planning a birthday party for Anna, but the preparations are, well, frozen when Elsa comes down with a cold.

Buck talked to USA Today about the short. "It's another side of Elsa the audience hasn't seen before and we hadn't really played with in the original feature," he said.

Frozen Fever will also include a new original song from Robert Lopez and Kristen Anderson-Lopez, the songwriters behind the Oscar-winning "Let It Go" featured in the original film.

Josh Gad, who voices Olaf, promised that the new song will be as catchy as ever.

"If history is any indicator, kids will go nuts," he told USA Today.

The short will debut in front of Disney's live-action fairy tale Cinderella when it hits theaters March 13.
