Kristoff is the tritagonists of the musical adapation of Frozen, based on the character of the same name.
Background[]
While his character traits and personality have remained faithful to the animated film, some changes have been made for the adaptation. The first of which is Kristoff's family; instead of trolls, the stage version has a group of Scandinavian creatures called the "hidden folk". They are summoned by a distinctive call that very few know, with Kristoff being one of those few.
In the stage version, Kristoff first meets Anna on Coronation Day, after she runs into his ice kart following "For the First Time in Forever". When Kristoff encounters Anna again in the midst of her journey to find Elsa, he provides her with a mountaineer outfit similar to his own, which she later gives up for her iconic winter gear when they meet Oaken in the second act of the show.
In response to the character's limited amount of singing in the film, Bobby and Kristina Lopez made sure to include Kristoff in a number of new songs for the Broadway play. One of which includes a duet with Anna called "What Do You Know About Love?". Replacing the wolf chase sequence, the song highlights Kristoff and Anna's differing opinions on the idea of "true love", with Kristoff questioning Anna's intelligence and Hans' legitimacy. During the number, Kristoff and Anna save each other from plummeting off a frozen bridge, which ensures them that they can trust each other. After Anna's heart is frozen by Elsa, Kristoff performs "Kristoff's Lullaby", a solo that acts as a reprise to "What Do You Know About Love?".
