Adventure Time (original title Adventure Time with Finn & Jake) is an American animated television series created by Pendleton Ward for Cartoon Network. It follows the adventures of Finn, a human boy and his best friend and adoptive brother Jake a dog with magical powers to change shape and grow and shrink at will.
