"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.

Declaring that it's "Adventure Time", Pen and Jake set off to the Ice King's mountain lair, fighting a cyclops and other large monsters in the process.

As he sheepishly leads Jake away, Pen spots some nearby ninjas stealing an old man's diamonds, and bid farewell to Princess Bubblegum as they run off towards their next adventure.

Ward spent around two weeks storyboarding the outline for "Adventure Time", a process that he later called "exciting" because he was "jumping into it not knowing whether [he] would sink or swim.

"[1] During the initial storyboard pitch to Frederator Studios, Ward brought a guitar and played the episode's theme song.

[1] Frederator's CEO Fred Seibert was initially disinclined to make the short, feeling it was too much of a "student film" and without much commercial appeal.

Neil Graf was tasked with coloring, Julian Narino was the background designer, and Adam Muto drew the props.

Graf and Narino later got jobs with other series and studios—King of the Hill and Laika, respectively—but Muto continued working with Ward and eventually became Adventure Time's co-executive producer and showrunner.
