The appearance of a stranger in the Candy Kingdom causes Finn to grow jealous.
Tropes
- Dark Is Not Evil: Lampshaded several times when Jake and Finn are analyzing Ricardio.
Jake: Some people look wicked but are super nice.
- Gross-Up Close-Up: There's a close up of Ricardio grinning evilly as he announces his plan to cut out Princess Bubblegum's heart and "make out with it".
- Hijacked by Ganon: Ricardio was created by The Ice King's magic.
- Organ Autonomy: Ricardio is a cartoony animated heart. The heart of the Ice King, to be precise.
- Reading Lips: While eavesdropping on Princess Bubblegum and Ricardio, Jake claims he can read their lips. Though it's pretty clear he's just making stuff up to mess with Finn, whom he thinks is over-reacting from jealousy.
Jake: (as Bubblegum) Hey, shorty! You should pick your boogers, and then fart. (as Ricardio) You look kinda like a big pink baguette.
- Subverted Suspicion Aesop: Just when it looks like Ricardio isn't a bad guy after all, the Ice King reveals that Finn had every right to be worried.
- Talk About That Thing: After Finn's outburst at the party, Jake takes him aside with the excuse "Hey Finn, you gotta come help slay these peanut monsters at the bar."
- Techno Babble: Ricardio and Princess Bubblegum's conversations are loaded with nonsensical technical speak.
- What Is This Feeling?: Finn doesn't seem to be familiar with the feeling of jealousy, and stubbornly refuses to admit that's what he feels.
- Wicked Heart Symbol: Ricardio the Heart Guy is an actual red heart with a face, arms, and legs. He manipulates Princess Bubblegum with the intention of cutting out her heart.
