PB schemes of how to free Lemonhope, and, as suggested by Finn, pulls a prank along with Finn on Lemongrab by exploding his pudding during dessert. PB says that Lemonhope is a brilliant boy, and should go to her kingdom, but Lemongrab snatches him away. Suddenly, both Lemongrabs burst in the door, and Lemongrab smashes Lemonhope's harp. 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 bathroom. While wandering around the castle, which seems to be falling apart, she discovers Lemonhope, a talented young Lemon Child singing a song of sorrow with his harp. PB says that she cannot watch the brothers fight anymore, so she wanders off. Lemongrab is outraged by this, and screams "UNACCEPTABLE" while Lemongrab two murmurs "acceptable." The two Earls then argue over this. Lemongrab Two, feeling pity, gives some of his bread to the child. While the show proceeds, the satisfied Lemongrab takes a Lemon Child's piece of bread, his only food, and eats it. He electrocutes the performers with a remote control button, which makes them do it faster and louder. The show consists of two lemon children, one smacking himself, and another just going "WHA" over and over, which does not please Lemongrab at all. Finn offers to play in it with his flute, but Lemongrab says that only Lemons are allowed. The gluttonous first Lemongrab smacks Lemongrab two with a leg of chicken for floating too high on his device, and greedily devours more food. Finn asks how PB is doing, but the Princess responds by telling Finn that something has happened to the two Lemongrabs, and that she is concerned because they used to be identical. Finn switches places with a Lemon Child named Duke Suck-lemon to sit next to PB. The Lemon Children enjoy the sophisticated party (in their own weird way), while servants serve lemon-based food. Instead, he instructs Lemon Head to announce that it is dinner time, who does so immediately. When Lemongrab 2 attempts to welcome them, the Earl stops him. The Earl of Lemongrab bends over and welcomes the two. Both Finn and Princess Bubblegum are surprised to see the changes in both of the Lemongrabs. He follows on a device that lets him hover.
Lemongrab 2 also appears, but his legs are gone and half his face is bitten off. The Earl of Lemongrab appears, having gained much more weight since the last episode he was in. One of the Lemon Children is dangling from the ceiling, and announces their arrival, but does not quite get their names right. When they enter the castle, the Lemon Children have significantly changed in appearance, now wearing fancy clothes and show signs of mild intelligence. As they are allowed through the gate, they enter a stagecoach that takes them to the castle. 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. Finn is already moving on after his breakup with Flame Princess, and visits Castle Lemongrab with Princess Bubblegum, only to find that things haven't exactly gotten better since their last visit.
