Trivia: In the musical number "In Summer," Olaf is on the beach and passes three different sandmen (the sand version of a snowman). The first one he passes furthest on the right is a nod toward the Coppertone sunscreen girl. Instead of a dog pulling down part of her bathing suit, the movie uses a seagull.

During the song, there are two hidden outlines of Olaf's body: one in his drink cup formed by ice cubes, and one formed by the clouds in the sky when he's lying on the picnic blanket.
