While Starfire attempts to broker peace, the other Teen Titans decide to have a Thumb War to decide which one of them is the dumbest in the group.
- Cassandra Truth: Before the Thumb War begins, Starfire constantly tries to prevent it by stating that their thumbs could get powerful enough to try and take over the rest of their body. None of the Titans believe her, and yet this is exactly what happens after the first few rounds of the Thumb War.
- Organ Autonomy: The thumbs end up gaining sentience after the Titans make them too powerful, and attack the Titans they're attached to in revenge for forcing them to fight each other.
- Shout-Out: Raven dresses up her thumb like a boxer and she dedicates her victories to "Adrian" as a reference to Rocky, while Cyborg's is dressed like The Terminator and speaks with Schwarzenegger's thick accent upon gaining sentience.
- Training Montage: The Titans decide to train their thumbs before actually engaging in war, with scenes such as Cyborg pushing a barbell with his thumb and Beast Boy using his thumb to squish various food.
- Win Your Freedom: The episode ends with Starfire finally brokering peace by having Raven cast a spell to remove everyone's sentient thumbs and allow them to go free and choose their own destinies instead of being stuck to the Titans. Despite everyone now being partially thumbless (including Starfire, who had dressed her own thumb up as a Swiss peacekeeper), Raven declares it a happy ending for everyone.
