"Adventure Time" is an animated short film created by Pendleton Ward, as well as the pilot to the Cartoon Network series of the same name. The short follows the adventures of Pen (voiced by Zack Shada), a human boy, and his best friend Jake (voiced by John DiMaggio), a dog with magical powers to change shape and grow and shrink at will. In this episode, Pen and Jake have to rescue Princess Bubblegum (voiced by Paige Moss) from the antagonistic Ice King (voiced by John Kassir).

"Adventure Time" first aired on Nicktoons on January 11, 2007, and later was showed in Fred Seibert's Random! Cartoons series showcase on December 7, 2008, subsequently leading to the creation of the animated series. It was nominated for an Annie Award for Best Animated Short Subject. The short and the later-produced television series share elements, but the two differ slightly in setting, conception and continuity, especially in regard to the post-apocalyptic setting, which is only featured in the television series.
