Adventure Time is an American animated television series created by Pendleton Ward. The series follows the adventures of Finn, a 14 year old human boy, and his best friend Jake, a dog with magical powers to change shape and grow and shrink at will. Finn and Jake live in the post-apocalyptic Land of Ooo. Ward describes Finn as a "fiery little kid with strong morals," while Jake is based on Tripper Harrison, Bill Murray's character in the movie Meatballs.
The series is based on a short produced for Frederator's Nickelodeon animation incubator series Random! Cartoons. After the short became a viral hit, Cartoon Network picked it up for a full-length series that previewed on March 11, 2010 and officially premiered on April 5, 2010, and the series has been a critical and commercial success.
