Adventure Time: Fionna and Cake

 When DJ Flame goes missing, Fionna turns to magic -- and an unlikely ally -- for help with the search. As Huntress attempts to navigate the Heart of the Forest alone, Marshall learns a critical truth about his mother.

 After Fionna and Huntress are captured, Cake tries to pull off Boys Night and save the lot on her own. Meanwhile, PB, Simon, and Marcie venture into the forest.

 After plunging into the unknown, Huntress faces off with an old foe, Fionna contends with painful memories, and Cake confronts her inner truth with help from the Karmic Worm.

 As time runs out for a wounded hero, PB turns to science for solutions, while Huntress fights to make her way back to Ooo to stop her. Later, Fionna seeks to undo a disastrous decision.
