Returning to the Land of Ooo: The Origins of Finn and Jake's Bond

Cultures · Published 9 October 2026 Swipe more like this →

In short: Adventure Time: Side Quests transports viewers back to the early days of the beloved franchise. By focusing on the childhood of Finn the Human and his developing brotherhood with Jake the Dog, the series trades complex, long-form storytelling for the lighthearted, standalone adventures that defined the original show's earliest seasons.

Developed by Nate Cash, a veteran director and storyboard artist from the original series, Side Quests serves as a deliberate expansion of the Adventure Time intellectual property. The project was first revealed by Warner Bros. Animation during the 2024 Annecy International Animation Film Festival. By the 2025 festival, creators showcased a draft of the opening title sequence, setting the stage for a production that prioritizes the whimsical, episodic nature of the franchise's roots.

The series distinguishes itself from more recent, serialized entries like Adventure Time: Fionna and Cake by returning to self-contained narratives. Episodes follow the duo as they navigate the Land of Ooo, interact with cloud people, and face off against familiar antagonists like the Ice King. This shift in tone is supported by a creative team including animation directors Victor Courtright and Niki Yang, art director Nick Cross, and story editor Darrick Bachman.

A significant change occurs in the voice cast to reflect the younger age of the protagonist. While most original voice actors, such as John DiMaggio and Tom Kenny, returned to reprise their legacy roles, Sasha Knight was cast as the young Finn the Human, taking over from Jeremy Shada. The auditory experience is further shaped by composer Matthew Janszen and a reimagined opening theme performed by the anti-folk group The Moldy Peaches.

The series debuted in the United States on June 29, 2026, via Disney+ and Hulu. Following its initial release, a second season consisting of 20 episodes was launched on October 2, 2026. International audiences gained access to the series starting October 5, 2026, through Cartoon Network and HBO Max, marking a rapid rollout for this nostalgic exploration of the franchise's foundational years.
