Plot

During Elsa's song "Let It Go", Olaf the snowman is brought to life. Before he can do anything however, Elsa releases her cloak which flies and knocks him down the mountain side until he crashes into a tree. Not knowing who he is, or why he is alive, Olaf decides to find an identity for himself. He comes upon Wandering Oaken's Trading Post and Sauna (where Kristoff can be heard singing "Reindeer(s) Are Better Than People" from the barn) and gets flattened by the front door by Anna who exits not noticing him and carrying a bag of carrots (which she will eventually give to Kristoff and Sven as payment).
