1. Adorable Olaf and his hilarious antics
"In Summer," which is a song he sang fantasizing about how much fun he would have in warm weather, dancing in the sun. "Bees-a-buzz, kids that blow dandelion fuzzAnd I'll be doing whatever snow does in summer.Olaf is obviously oblivious to the fact that he would melt in summer, because of this, this song is witty. Olaf represents a character who is so adventurous, yet doesn't know anything about this world, that it is almost a fault. Because he was built by Anna and Elsa when they were still small, he represents pure childish innocence.
"Oh, and I don't know why, but I've always loved the idea of summer, and sun, and all things hot.. -Olaf
