Olaf

Olaf is one of the tritagonists (the other being Sven) in the upcoming 2013 film Frozen.

Official Disney Bio
"He’s Olaf and he likes warm hugs. Sprung from Elsa’s magical powers, Olaf is by far the friendliest snowman to walk the mountains above Arendelle. His innocence, outgoing personality and uncanny ability to disassemble himself at good and not-so-good times lead to some awkward, albeit laughable moments. He may also have the world’s most impossible dream, but what he doesn’t know won’t melt him—or will it?"

Background
Olaf is a goofy, enchanted snowman. He was the very first snowman enchanted by Elsa the Snow Queen as part of the snowmen army that was meant to guard and protect the Snow Queen in her ice palace after her self-exile. However, Olaf was a failure, coming out as incredibly bumbling, yet lovable, as opposed to fierce and sinister as intended. In spite of being a snowman, Olaf actually longs for summer.

Disney Parks
Olaf has been confirmed to host the upcoming winter themed version of World of Color this year in Disney California Adventure.
