Adventure Time Side Quests UK Disney Plus Availability
Adventure Time: Side Quests is the episodic spin-off that returns Finn and Jake to their earlier adventuring years, and UK viewers have been searching hard for a Disney Plus route to watch it. The series premiered in the United States on June 29, 2026 on Disney+ and Hulu, with a second batch of 20 episodes landing on October 2, 2026. Because Disney handles regional releases market by market, UK availability may not mirror the US schedule exactly, and the Cartoon Network international rollout starting October 5, 2026 is the clearest signal that new territories are receiving the show this autumn.
Video Highlights:
- Official trailer confirms episodic, standalone adventures in the Land of Ooo
- Younger Finn and Jake front and center
- Classic elements including Ice King referenced in the series description
Disney+ libraries differ by country. The June 29 and October 2, 2026 dates are US release dates. UK viewers should verify the series listing on their own Disney+ app, and watch for Cartoon Network UK scheduling announcements tied to the October 5, 2026 international rollout.

How UK Viewers Can Start Watching
Check Disney+ UK First
Search for Adventure Time: Side Quests in the Disney+ UK app or on the web. If the series listing appears, both batches may already be available following the international rollout.
Watch for Cartoon Network UK Announcements
The international Cartoon Network schedule beginning October 5, 2026 indicates when broadcast territories receive the series. UK broadcast news typically follows these windows.
Watch the Official Trailer
The Cartoon Network official trailer (~385K views) previews the episodic adventure format, the returning duo, and classic Ooo elements.
Start With Episode 1 in Order
Release order is the simplest watch order. Each episode stands alone, but sequence keeps recurring details consistent.
Track New Drops via Episode Listings
Follow the Disney+ listing and TV Guide episode tracker to see when new episodes reach your region.
Side Quests works as an entry point. The original Adventure Time adds background, but the episodic structure means you can start with any listed episode and still follow the adventure.
Streaming Platforms Compared
| Platform | Region Focus | Content Type | Best For |
|---|---|---|---|
| Disney+ | US confirmed; UK subject to listing | Both episode batches, streaming | On-demand binge viewing |
| Hulu | US only | Streaming, batch releases | US subscribers inside Disney bundle |
| Cartoon Network | International incl. UK broadcast | Linear TV airings | Traditional TV viewers |
| Official YouTube trailer | Worldwide | Trailer and promos only | Previewing before subscribing |
Unlike the US, the UK typically receives Cartoon Network franchises through a mix of Disney+ licensing and linear broadcast. Whichever arrives first, the 40-episode library means UK fans get a substantial season once the rollout completes.
