Too Old

Synopsis
Finn is already moving on after his breakup with Flame Princess, and visits Castle Lemongrab with Princess Bubblegum.

Plot
The episode opens with the gate keeper at Castle Lemongrab checking Princess Bubblegum's passport, and Finn on the phone with Jake who is trying to advise him against doing this dinner with Bubblegum because of his recent break-up with Flame Princess. As they are allowed through the gate, they enter a stagecoach that takes them to the castle. When they enter the castle, the Lemon Children have significantly changed in appearance, now wearing fancy clothes and show signs of mild intelligence. One of the Lemon Children is dangling from the ceiling, and announces their arrival, but does not quite get their names right. Lemonblack appears, having gained much more weight since the last episode he was in. Lemonwhite also appears to the bottom left of him, whose legs are gone and half his face is bitten off, follows on a device that lets him hover. Both Finn and Princess Bubblegum are surprised to see the changes in both of the Lemongrabs. Lemonblack bends over and welcomes the two. When Lemonwhite attempts to welcome them,Lemonblack stops him hostily. Lemonblack orders one Lemon Child to announce that it is dinner time, and does so immediately.

The scene shifts to the dinner table. The Lemon Children enjoy the sophisticated party (in their own weird way), while servants serve lemon-based food. Finn is sitting next to a little lemon child named Duke Sucklemon, but wants to sit next to PB. He switches their table nametags, which makes the Duke move over. Finn asks how PB is doing, but the Princess responds by telling Finn that something has happened to the two Lemongrabs, that they were once the exact same. The gluttonous Lemonblack smacks Lemonwhite with a leg of chicken for floating too high on his device, and greedily devours more food. He then orders for a floor show. Finn offers to play in it with his flute, but Lemonblack says that only Lemons are allowed. The show consists of two lemon children, one smacking himself, and another just going "WHA" over and over, which does not please Lemonblack at all. He electrically shocks the performers with a remote control button, which makes them do it faster and louder. While the show proceeds, the now-pleased Lemongrab takes a Lemon Child's piece of bread, his only food, and eats it. Lemonwhite, feeling pity, gives some of his bread to the child. Lemonblack is outraged by this, and screams "UNACCEPTABLE" while Lemonwhite murmurs "acceptable..." The two Earls then argue over this. PB says that she can't watch the brothers fight anymore, so she wanders off.

In her travels, she discovers Lemonhope, a talented young Lemon Child singing a song of sorrow. PB loves the little boy instantly, and says that he can come to the Candy Kingdom with her because Lemonhope says Lemongrab hates him and his music, locking him in a filthy latrine. Suddenly, both Lemongrabs burst in the door, and Lemonblack smashes Lemonhope's harp. PB says that Lemonhope is a brilliant boy, and is to go to her kingdom, but Lemongrab snatches him away. PB schemes of how to free Lemonhope, and, as suggested by Finn, pulls a prank along with Finn on Lemongrab by exploding his lemon-pudding during desert. This gets both PB and Finn stuck in the dungeon with Lemonhope. Lemonhope plays Finn's flute, though awfully. Suddenly, both Lemongrabs dance into the room, hearing the awful noise as beautiful music. Lemomwhite releases them all, to the utter anger and outrage of Lemonblack. Lemonwhite one says that his clone is too soft, and he again eats his brother whole.

Princess Bubblegum, Lemonhope, and Finn escape, but find that the castle gates are locked. Finn suggests pranking him again, but PB states angrily that that will not work, and that she is too old for that stuff. Suddenly, Lemonblack appears on a balcony, and orders all of his children to kill all three of them. During the battle, Lemonwhite forces his way halfway out of his brother's mouth to stop the fight. He tells them all to listen to him, and he releases them from service to his tyrant clone. He says:

Lemonblack eventually forces his brother back into his stomach. The Lemon Children help the three heroes over the castle gate, while Lemonblack stares at Lemonhope in hatred.

Jake calls Finn, and Finn suggests that he patches things up with FP, realizing how it feels to be manipulated, and that PB is just too old for him. Jake teases Finn about Flame Princess already having a new boyfriend, but quickly adds that maybe she does as the episode ends.

Cultural references

 * In the place of Finn's signature, Kilroy can be seen on Finn's passport when the Lemon Gatekeeper admits Finn and Princess Bubblegum.
 * Finn's passport closely resembles an Australian passport.
 * 'Big' Lemongrab strongly resmebles Baron Harkonnen from the film version of Dune.
 * The white Lemongrab's hover chair strongly resembles Yoda's hover chair from the third "Star Wars" movie.

Episode connections

 * The title is a reference to "Too Young." Also, many events in this episode also parallel the events of "Too Young."
 * Finn uses the phone talking to Jake at the beginning and end of the episode, similar to Jake's pep talk to Finn in "Too Young."
 * The way the Lemon Child announced Finn and Princess Bubblegum's arrival was the same way Manfried announced the Earl's arrival.
 * After the Lemon Child announced Finn and Princess Bubblegum's arrival, another Lemon Child fell from a trapeze to the ground, much like Cinnamon Bun did after Manfried announced the Earl's arrival.
 * Princess Bubblegum notes that the castle has fallen into disrepair since she last saw it, mirroring Lemongrab's opinion that PB's castle was in "unacceptable condition."
 * Finn asks Princess Bubblegum if she wants to prank Lemongrab "like old times" similar to how he and younger Princess Bubblegum pranked Lemongrab.
 * The way Finn and PB crawl to the counter to place the prank is also similar to the way they did in the former episode.
 * Lemongrab says that Princess Bubblegum is too old for pranks at the last part of the episode.
 * Lemongrab still has his glasses for his farsightedness from "Too Young."
 * The title card music and music when PB and Finn prepare the prank is also the same from "Too Young."
 * Finn still has the spicy hot sauce they used in "Too Young."
 * PB says, "Excuse me, Finn," just like in "Too Young."
 * The events of "Frost & Fire" are referenced, when Jake mentions Finn "breaking up" with Flame Princess.
 * Lemongrab 2 now has no legs, a bite mark on his head, and relies on a floating device to move. His injuries presumably come from when his brother ate him in "Another Five More Short Graybles," but he was eaten whole this time by Lemongrab after releasing Finn, Princess Bubblegum, and Lemonhope.
 * The Lemon Children who were first seen in "All Your Fault" have been growing up, and can now talk.
 * Finn's (previously broken) flute from "Prisoners of Love" returns.
 * This episode continues the saga for the Lemongrab's food troubles. In "All Your Fault" the Lemon Kingdom had no food and the Earls used their seeds to make more children. In "Another Five More Short Graybles" they are arguing over raising a LemonPuppet, resulting in The Earl trying to eat his clone. In "Too Old" Earl succeeds and eats his Lemongrab clone.

Errors

 * When the Lemon Children are pulling at Finn's hat, he doesn't appear to have any hair.
 * As Finn is talking to Jake at the end of the episode, a small part of Finn's phone disappears then reappears.
 * When Lemongrab enters the bathroom to stop Lemonhope from playing his harp, he has to squeeze through the doorway to get in. However, when he leaves, he fits and is unobstructed.
 * The synopsis listed on fios on demand says, "Finn, Jake, and PB discover a talented mutant named Lemonsqueak at The Pageant of the Mutants. Now they must find a ways to free him from the lemongrabs." This description misspells Lemonhope's name as Lemonsqueak, and Lemongrab Castle as The Pageant of the Mutants. Jake is also not present in the rescue of Lemonhope, but the synopsis says that he is. In the episode, he stays at home.

Storyline analysis

 * This is one of the many episodes in which Princess Bubblegum appears overly rational and laid-back, giving the impression that she does not enjoy having fun. In "Too Young," Princess Bubblegum is freed from responsibility and shows a more fun-loving side, and, in other episodes, she often behaves differently when excused from royal duties. The reason Finn seems to think that Princess Bubblegum isn't as fun in this episode is probably not because of her overall personality, but instead because she is shown to constantly put her citizens, responsibilities, and morals before everything else. Finn's misunderstanding of this may be because of their age difference, once again supporting the idea that Bubblegum and Finn cannot be together due to age. This makes Finn realize that Flame Princess is really the one for him.
 * Lemongrab's castle is relocated to a forest since in "All Your Fault," Lemonjon died with the castle falling.
