Slime Princess needs a husband or else she'll lose the Slime Kingdom to her obnoxious sister. Finn steps in to save the day, but first they will need to win a series of Love Games to prove to the Slime people that they are really in love.
Tropes
- Attractiveness Isolation: The real reason that Blargatha created the identity of Guillermo is that she's so hot both men and women alike are too intimidated by her to talk to her.

- Ascended Extra: Slime Princess becomes a major character in this episode.
- Beard of Evil: Guillermo has a long, bushy mustache.

- Ice King is still living with Finn and Jake after his house was destroyed in "Frost and Fire".
- Tree Trunks and Mr. Pig are still dating, as shown dancing in this episode.
- A Day in the Limelight: Slime Princess gets a major focus in this episode.
- Dreadful Musician: Blargatha is a terrible singer, so she completely loses the crooning part of the Love Games, to Finn's heartfelt song about his lingering feeling for Flame Princess.
- Evil Plan: Slime Princess would've been ok with not ruling if her sister and her husband weren't planning to militarize their country and conquer Ooo.

- Informed Attractiveness: Slime Princess's younger sister Blargatha is apparently much hotter than her even though to the viewers they look identical.
- Old-Fashioned Rowboat Date: The "Crooning" Part of the competition involves the couples rowing out to the middle of a lake, where one must sing to their partner.
- Plucky Comic Relief: Jake lampshades this will be his role in the episode.
- The Reveal: Guillermo is not even a real person, just a puppet Blargatha created to inherit the kingdom with.
- The Speechless: Guillermo doesn't say a word mainly because he's merely a puppet created by Blargatha to inherit the throne.
- Take Over the World: The Slime Princess' younger sister and her husband's plan is to conquer Ooo.
- Undercover as Lovers: The plot is based around Finn being forced to pass himself off as Slime Princess's new husband.

- Vocal Evolution: Finn manages to sing a love song pretty well without his usual heavy auto-tuning.
- Vomit Indiscretion Shot: Finn vomits when he tries to practice kissing Slime Princess in her room. Later Slime Princess does the same thing in front of the whole kingdom when the people demand that they kiss.
