While partying with Finn, Flame Princess is tricked into wagering her kingdom on a rap battle against the Son of Rap Bear.
- Absurdly High-Stakes Game: The whole Fire Kingdom is wagered on a rap battle. During her rap, Flame Princess points out it wasn't hers to give away—just being its ruler doesn't mean she owns it.
- Dragon Ascendant: After the King of Ooo was reduced to a puddle, Toronto had decided to become a lead Con Man.
- Farts on Fire: As a part of one of her performances Flame Princess farts fire onto various targets.
- Jerk with a Heart of Jerk: Flame Princess is hopeful when she sees Flame King in the audience of her rap battle, but it turns out he had no idea she was performing and expects her to lose.
- Off-Model: Flame Princess is consistently drawn as being several inches taller than Finn throughout the episode, when previous episodes had established they were roughly the same height.
- Pretender Diss: During Flame Princess' rap, she tells off her father, insisting she doesn't need him because she's "the real Flame King", and calls Son of Rap Bear a copycat who broke his dad's legs so he could take his name instead of coming up with his own.
- Read the Fine Print: FP signs a contract to rap in concert, which Toronto (in disguise) insists is standard, but actually says she'll give him her kingdom if she loses.
- "The Reason You Suck" Speech: At one point, Flame Princess rap is pretty much just her calling her father, Son of Rap Bear and Toronto jerks and calling them out on their actions, which is her father's bad parenting, Son of Rap Bear's mistreatment of his father and Toronto's scamming.
- Reformed, but Not Tamed: Flame King may be living peacefully, but he's still horrendously unapologetic for how he treated his daughter. He even assumes she came to apologize for imprisoning him, when he was jailed for evil acts he committed and let go, whereas he permanently imprisoned and tried to kill her just for being a potential threat.
- Sheltered Aristocrat: Son of Rap Bear's initial dissing of Flame Princess focus on how she spent most of her life locked in a lantern, claiming she has no life experience to rap about. She agrees, noting that most of her rapping is about her rapping, and tries to go on adventures and do odd jobs. Ultimately, this isn't enough, so she raps about what she does know—dealing with her father and ruling the Fire Kingdom.
- Weapons-Grade Vocabulary: Son of Rap Bear's rapping causing his opponents body parts or the surroundings to break apart. He takes off multiple limbs of both his father and one of his opponents.
