Adventure Time: Side Quests Debuts on Disney+ and Hulu With All 20 Episodes Available Now

[game=ADVENTURE TIME: SIDE QUESTS], a prequel to the beloved original series, debuted on June 29, 2026, on Disney+ and Hulu with all 20 episodes available for streaming. Fans can watch the entire season immediately, as the full lineup was released at once, eliminating the need to wait for weekly installments.

The series revisits Finn's childhood, exploring his earliest adventures with Jake and offering new insights into the beginnings of their friendship. This fresh perspective deepens the backstory of familiar characters and their origins.

Sasha Knight voices Finn, while John DiMaggio returns as Jake, ensuring the main duo retains their signature charm and dynamic. Classic characters like the Ice King also make appearances, bringing back fan favorites and their trademark humor.

Early reviews have been positive: ComicBook.com awarded the series a perfect 5 out of 5, Discussing Film gave it 4 out of 5, and Screen Rant rated it 8 out of 10. Aggregator ratings are not yet available, as the show has just launched.

This is a self-contained story with no additional seasons planned. All 20 episodes comprise the complete narrative, making it a rare case where fans receive the entire story in one release.

Later this autumn, the series will also become available on HBO Max and Cartoon Network, expanding its reach to even more viewers.
