Parents beware - the first pictures from Disney’s Frozen follow-up have been released.
But rather than following Elsa and her gang for a full 90 minute feature-length film, the short sequel will last only seven minutes.
However, the follow-up will include a new song from husband and wife team Robert Lopez and Kristen Anderson-Lopez, the brains behind catchy soundtrack “Let It Go”.
“If history is any indicator, kids will go nuts,” director Chris Buck told USA Today about the new tune, two months after Frozen director Jennifer Lee apologised to parents for the popularity of "Let It Go".
Speaking about the plot of Frozen Fever, Buck said: “It’s another side of Elsa the audience hasn’t seen before and we hadn’t really played with in the original feature.”
The new photos show Anna playing with her older sister, whose icy attitude appears to have thawed as she throws the princess a birthday party.
The short film is due to be shown in cinemas before Disney’s live-action Cinderella film, which is out in March.
Frozen became the highest-grossing animated film of all time after its release in 2013, taking $400 million at the worldwide box office.
The Disney film won two Oscars for Best Animated Feature and Best Original Song.
