Adventure Time: Side Quests (2026)

S01E16 Key Quest

Finn and Jake accidentally zap the Ice King into the treehouse mid-nap—and to their horror, he’s completely naked. Mortified, the Ice King begs them to help him find his spare castle key before anyone sees him like that. As they sneak through the Candy Kingdom, avoiding horrified stares and awkward run-ins, the trio must retrieve the hidden key and get the Ice King back home before his dignity (and everyone’s sanity) is shattered for good.
