Do You Wanna Build a Snowman

The song is performed in the film by Kristen Bell, Agatha Lee Monn, and Katie Lopez, each playing the role of Princess Anna at different ages. It occurs near the beginning of the film when Elsa has been locked away in her room because her parents are afraid of her losing control of her powers and hurting Anna. As the girls grow older together, they are kept apart. After their parents are killed in a storm at sea, Anna once again sadly asks her sister to come out, to no avail.
