Fed up with Jake's antics, his son Kim Kil Whan takes action.
- Always Need What You Gave Up: Sure could have used that treasure they just got rid of.
- Artistic License – Law: Despite Jake's speech on how laws are oppressive, knowledge of them would have come in handy here. Marceline basically gave the Tree Fort to Finn and Jake, meaning Kim Kil Whan had no authority to make all the changes that he did. Likewise, just because Jake's gold bone was on his property it does not mean he owned it.
- Batman Gambit: Kim Kil Whan did what he did in hopes of teaching his dad responsibility.
- Beard of Evil: Kim Kil Whan sports one, though he isn't exactly evil, just amoral and deadpan.
- Be Careful What You Wish For: Kim Kil Whan's motive for this episode was trying to get his father to become a responsible adult. Except that in "Jake the Dad", he was trying to be responsible. He moved out of the Tree Fort and gave up the adventuring lifestyle to take care of his family. However Kim Kil Whan and his siblings grew to adulthood in a few days and the episode ended with them convincing their smothering father that they could take care of themselves, getting rid of the only reason Jake would need to be responsible.
- Bizarre Instrument: Kim Kil Whan bartered the Tree Fort from Marceline for a bass with a ridiculous number of necks.
- Call-Back:
- Finn and Jake's treasure room is still empty, as per the events of "Furniture and Meat".
- Kim Kil Whan references the fact that Marceline once owned the treehouse.
- Cerebus Retcon: Those times that Jake's children have appeared on-screen since "Jake The Dad" are the only times that he's ever spoken to them. Gives a whole new meaning to the lengths Jake Jr. went to in order to do a caper with him in "One Last Job", and how awkward Jake was with her in "Another Five More Short Graybles".
- Corrupt Corporate Executive: Kim Kil Whan is a very successful and wealthy buisnessman who buys the deed to his dad's treehouse to become his landlord and divides it into 37 apartments (basically having one person per room, including the bathroom) and teach him responsibility on whim and when his dad tries to buy the back the house he refuses because he's rich.
- He categorizes everything into old business and new business.
- Daddy's Girl: Jake Jr. may be Jake's favorite but Jake's other daughter Viola adores him despite Jake apparently never seeing her or the other kids.
- Foils: Jake Jr. gets Jake's attention but she acts fairly indifferent around him; Viola yearns for her dad's attention but makes excuses when he's not there. Kim Kil Whan is mature, in a relationship, independent, and well-off; his brother TV is a Manchild who cares only about his computer time and lives with his mom (third sister Charlie hasn't had any lines yet).
- Equivalent Exchange: After getting rid of all their loot in "Meat and Furniture" the only thing Jake has to pay to Kim Kil Whan for rent is two antique photos he got at a yard sale; Kim Kil Whan accepts and lets them sleep on the former loot room's equally antique ladder.
- Evil Debt Collector: Jake fears Kim Kil Whan's behavior is because he owes money to evil gangsters.
- Work Off the Debt: After Kim Kil Whan bails Finn and Jake out of jail for "trespassing" in their own home (going into the new residents' areas without their permission) he tells them to get regular jobs to pay him back.
- Guilt by Association Gag: Kim Kil Whan is angry at his dad for being late at the birthday party and for a being a poor father in general is perfectly understandable. But he buys the house to teach his dad responsibility in a way that would normally makes us root for him...except that everything he makes Jake go through, he makes Finn go through too, who does definitely not deserve it.
- Happily Married: Kim Kil Whan and a lady bear.
- (even more) Interspecies Romance: They have a daughter named
Bronwyn.
- (even more) Interspecies Romance: They have a daughter named
- Innocently Insensitive: Jake just doesn't understand that his son is mad at him because he's been acting like an immature jerk. Although he is vaguely aware that it's because of something he did.
- Jerk with a Heart of Gold: Kim Kil Whan is this. He loves his dad and wants to teach him responsibility but he utterly humiliates his dad by buying the Tree House behind his back, and since he has no money makes him and Finn live on a ladder, and divides the rest of the house into 37 apartments and when Jake tries to buy the house back with a golden bone, he claims that bone became his when he bought the house since it was buried in the yard, out of spite. Instead of you know just talking to his dad about his issues.
- Jerkass Ball: Jake is incredibly rude in this episode: he's three hours late for his own kids' birthday party (and doesn't bring any presents); he's usually a good cook and was in charge of the food but all he brings is a lump of cold macaroni salad he'd kept in his "pocket" all day; he shows affection toward Kim Kil Whan only because he can't pay him off to get the treehouse back; the title ocarina (a make up present for Kim Kil Whan) can't actually be played because it's a solid lump of clay.
- Might Makes Right / Screw the Rules, I Have Money!: Via io9's recap
: "[Finn] can't understand how Kim Kil Whan can just show up one day, and say he owns their house when it's their house. Jake tells him it's simple, the laws aren't there to protect the common man [represented by small white figures], they're there to help the rich [represented by large red figures] stay rich." - Parental Neglect: A father bird doesn't notice all of his helpless babies falling out of the nest. All of the times we saw Jake's kids on-screen were also the only times he saw them; Jake only shows "father-love" to Kim Kil Whan when he realizes he can't use money to change his mind (though he's also relieved his son doesn't owe money to evil gangsters).
- Rules Lawyer: Jake tries to give Kim Kil Whan a giant golden bone he buried in the yard; Kim Kil Whan reasons that because he owns the property the bone already belongs to him so Jake is just giving him his own property back and destroying his yard proably out of spite.
- Supernaturally Young Parent / Plot-Relevant Age-Up: Verizon's placeholder description for Adventure Time describes Jake as Finn's "28 year old brother" (in dog years, presumably); Jake Jr. said she's "basically 30" last season and Kim Kil Whan acts like a responsible 40 year old here.
- Tall Fancy House: Kim Kil Whan's house is a comfortably furnished three-story building in the middle of a fairytale forest (complete with fairy).
- Tough Love: Kim Kil Whan wants his father to grow up so he buys the treehouse and demands that Jake and Finn get jobs and pay rent or leave. He eventually decides that Jake is fine as he is (or realizes he'll never change and gives up).
- Wacky Parent, Serious Child: Jake and Kim Kil Whan.
- Warts and All: At the end of the episode, Kim Kil Whan laments not being able to get his father to be more mature and responsible, but concludes that underneath it all Jake's still a good guy.
- Wise Beyond Their Years: Kim Kil Whan and the rest of his siblings (mostly), considering this is possibly their first birthday.
