At a trading post on her journey, Anna meets a mountain man and ice harvester named Kristoff and his reindeer Sven. Kristoff agrees to lead her to the North Mountain, where he knows that a magical phenomenon has occurred. The group are chased by wolves on the way and later encounter a happy-go-lucky snowman named Olaf, who was unknowingly brought to life by Elsa, whom Anna remembers from her and Elsa's childhood, and he later helps lead them to her palace. The sisters reunite, and Anna hopes to rekindle their relationship. However, Elsa, while forgiving her for the cornation incident, turns down Anna’s help and orders her to leave. Anna informs her of the eternal winter that has engulfed Arendelle. Upset and stressed, Elsa loses control of her powers, striking Anna in her heart and thus endangering her health. Anna, followed by Kristoff and Olaf, is then chased out by a giant snow creature, whom Olaf names Marshmallow. Anna’s hair starts to turn white and she begins to shiver more as a result of Elsa's accidental strike. Concerned about her and her health, Kristoff takes Anna to his family, who happen to be the trolls, to Anna's surprise. Once they arrive, the trolls believe Anna is Kristoff's girlfriend, but when told otherwise, they try to get them together by convincing them of their feelings for each other. As Kristoff and Anna try explain the real reason why they're there, they find themselves genuinely falling for each other. However, their moments are short-lived as Anna collapses and nearly faints in Kristoff's arms. Grand Pabbie, who awakens from his nap and senses the magic inside Anna, sadly informs her and Kristoff that Anna's heart has been accidentally frozen by her sister and although magical, he is unable to remove the ice. He adds that only an act of true love can save her from freezing completely. Kristoff, believing that a romantic kiss from Hans will heal her, rushes Anna back to the kingdom with him holding her on Sven's back, Olaf following behind them.
