Quick recap
Olaf comes to life in the middle of "Let It Go," as Elsa walks off to build her ice palace, and he's left alone on the mountain with no idea who he is. Curious about everything, he heads down into the world to figure out what he likes and what he's missing, starting with a nose. Along the way he gets into trouble only a snowman could manage and falls for the idea of summer, which he has never seen. The short ends right where Olaf meets Anna, Kristoff and Sven in the woods, the meeting Frozen already showed.
