Samantha was thrown into the same pit Jake was in, because she tried to steal Kee-Oth' Blood. While in the pit Samantha and Jake started to bond with each other, because Samantha said that she hadn't seen a male dog in years. She states that she doesn't fight because of romantic issues, but when Jake rebuffs she they start fighting each other with Samantha winning due to Jake losing his blood and energy to Kee-Oth.
When Finn and Lady Rainicorn arrive to save Jake, where they trick Kee-Oth into sucking up a sword made from grape juice which makes him explode. After Jake gets his blood back, he helps Samantha out of the Pit and they all return to the tree house. Samantha then leaves stating that she and Jake should fight one day.
