Sprung from Elsa's magical powers, Olaf is by far the friendliest snowman to walk the mountains above Arendelle. His greatest desire is to see summer, which, of course, he is unable to do due to the fact that he will melt in the sun.
Players were able to adopt a Snowman Puffle that resembles Olaf, dress up as him, and transform into Olaf himself.
He was the first character to exist in the form of a costume and a transformation. The second was Marshmallow.
He guided you through the party quest to find the three magical snowflakes hidden in each room.
