Adventure Time: Side Quests (2026)

S01E18 Re-Run Dungeon

Jake is hyped to finally see Finn’s legendary childhood dungeon, but when they arrive, Finn is totally let down—it’s just a boring, dusty hole. Determined to recapture the magic, Jake goes full overdrive, rigging traps, adding monsters, and dialing up the danger to make the place as epic as Finn remembers.
