Sven

"Who's my cute little reindeer?!"

- Olaf to Sven

Sven the Reindeer (simply known as Sven) is one of the primary characters in the upcoming 2013 film Frozen.

Official Disney Bio

 * A reindeer with the heart of a Labrador, Sven is Kristoff’s loyal friend, sleigh-puller and conscience. He makes sure his mountain-man companion is the stand-up guy Sven knows and loves, and does so without saying a word. A few emphatic snorts usually get his point across. Life would be perfect if only Kristoff would lose that ridiculous reindeer voice he likes to use when speaking for Sven (as if reindeers really talk that way).

Background

 * Taken from the official D23 website

“Sven the reindeer is a great character in the film; it’s hard to take your eyes off of him. He is Kristoff’s reindeer and we created him to be like a big, lovable Labrador dog. But he can also get his mojo on when he needs to and be serious. He is just the kind of Disney character that you’ll want to take home with you.”

Disney Parks
Along with Olaf, Anna, and Elsa, Sven is set to appear in the upcoming winter themed version of the nighttime spectacular, World of Color in Disney California Adventure late 2013.

Trivia

 * Unlike Olaf, Sven will not speak. However, as mentioned above, Kristoff comically does voice overs for the reindeer.
 * Whislt the filmmakers have noted Sven's behavior being based off that of a dog (or a Labrador to be more precise) real reindeer actually pant much like canines.
