The Adventure Time animated franchise is leaving the Warner Bros. Discovery ecosystem for the first time — the latest spinoff, Adventure Time: Side Quests, will be released on Disney+ and Hulu in the U.S. The animated series is set to premiere June 29.

Side Quests, produced by Cartoon Network Studios, was announced at the 2024 Annecy International Animation Film Festival as part of the Warner Bros. Animation slate with no network attached. The Emmy-winning mothership series ran on Cartoon Network for 10 seasons; offshoots Adventure Time: Distant Lands and Adventure Time: Fionna and Cake were carried by sibling streamer HBO Max, which has been pulling back on kids’ and family animation.

The joint release by Disney+ and Hulu is unusual as the two streamers have their content lanes; it is another indications of the Disney platforms’ closer integration.

Side Quests follows young hero Finn and his magical dog best friend Jake as they embark on adventures across the fantastical land of Ooo — partying with cloud people and punching evil in the butt along the way.

Finn the Human is voiced by Sasha Knight and John DiMaggio returns as the voice of Jake the Dog. The series will also reunite familiar characters including Ice King (Tom Kenny), Princess Bubblegum (Hynden Walch), Marceline (Olivia Olson), and BMO (Niki Yang).

“Making Side Quests felt like making the original Adventure Time, which felt like hanging out with art school buddies making professional cartoons,” said showrunner and executive producer, Nate Cash. “That sounds like a big sandwich of feelings, and it was! You’re going to love these NEW adventures with Finn & Jake!”

Adventure Time: Side Quests is executive produced by Cash, with Darrick Bachman serving as Story Editor. Victor Courtright and Niki Yang direct, Nick Cross is the Art Director, and Matthew Janszen is the Composer.
