Adventure Time: Side Quests is an American animated television series developed by Nate Cash and produced by Cartoon Network Studios. The series serves as a soft reboot of the animated series Adventure Time. The first season of Adventure Time: Side Quests premiered in the United States on Disney+ and Hulu on June 29, 2026. A second season is set to be released in late 2026.
Premise Set during the early chronological timeline of the Adventure Time universe, the series focuses on the childhood of Finn the Human and chronicles the early development of his brotherly bond with his magical dog, Jake the Dog. Shifting away from the heavy, multi-season serialization found in later franchise projects like Adventure Time: Fionna and Cake, Side Quests is constructed around lighter, self-contained, and standalone episodic stories akin to the early seasons of the original show. The narrative follows the duo completing odd jobs, interacting with cloud people, exploring the Land of Ooo, and engaging in playful confrontations with classic villains like the Ice King.

Production
Development The project was originally greenlit and publicly announced by Warner Bros. Animation at the 2024 Annecy International Animation Film Festival as part of an expansion of the Adventure Time intellectual property under Cartoon Network Studios. Longtime original series director and storyboard artist Nate Cash was attached to develop the concept as showrunner and executive producer. At the 2025 iteration of the festival, a work-in-progress draft of the series' introductory title sequence was screened for attendees. In May 2026, Cartoon Network officially unveiled the series' production staff and core voice cast. Victor Courtright and Niki Yang were confirmed as the primary animation directors, with Nick Cross serving as art director and Darrick Bachman managing the script workflow as story editor. In July 2026, a second season was announced, also consisting of 20 episodes.
Casting The series features the return of the vast majority of the original program's principal voice actors reprising their legacy roles, including John DiMaggio, Tom Kenny, Hynden Walch, Olivia Olson, and Niki Yang. Because the series focuses explicitly on Finn's early childhood, actor Sasha Knight was cast to voice the young Finn the Human, succeeding Jeremy Shada who voiced the adolescent and adult versions of the character across previous media entries.
Music The musical score for Side Quests is composed by Matthew Janszen, who previously collaborated with showrunner Nate Cash on the Warner Bros. animated series Tiny Toons Looniversity. The series' new opening theme song consists of a reimagined rendition of the theme song from the original series, performed by the American anti-folk band The Moldy Peaches.
Release Adventure Time: Side Quests released on June 29, 2026, on Disney+ and Hulu in the United States, and will release internationally on Cartoon Network and HBO Max on October 5, 2026. A second season is set to be released in late 2026.
