The episode was written and storyboarded by Ako Castuera and Jesse Moynihan, from a story by Patrick McHale, Kent Osborne, and Pendleton Ward.

However, while knocked out, both Finn and Jake are visited by a mysterious Dream Warrior (voiced by Matthew Broderick), who gives them the advice that they need—albeit in the form riddles—to defeat The Farm; he tells them to use cheap fighting moves to obscure the creatures vision, pull down his pants, and bite his buttocks.

"Who Would Win" was written and storyboarded by Ako Castuera and Jesse Moynihan, from a story developed by series creator Pendleton Ward, Patrick McHale, and Kent Osborne.

[3][4] According to Moynihan, the episode revolves around several themes, such as whether Finn could hold his own against the seemingly unstoppable Jake in a fight, and the idea of willpower overcoming physical limitations.

Moynihan inserted this reference to maintain continuity with the second season episode "Mortal Folly", which features a scene with Finn daydreaming that he has a bionic arm.

Gammill plays The Farm, a character that both Ward and Moynihan expressed an interest in bringing back to the show the DVD commentary for the episode.
