As the song says, “You know Dasher and Dancer and Prancer and Vixen, Comet and Cupid and Donner and Blitzen. But do you recall the most famous reindeer of them all?” OK, so the song might not be about Sven, the loyal, loveable reindeer who helps Elsa, Anna and Kristoff save Arendelle, but doesn’t Sven deserve a song of his own? Bring home Pop! Sven and you’ll always have transport through the snow.
