Lady & Peebles

Synopsis
Princess Bubblegum and Lady Rainicorn look for Finn and Jake, who are missing after a run-in with the Ice King.

Plot
Princess Bubblegum and Lady are trying to find Finn and Jake who have been missing for three weeks after battling with the Ice King. Lady discusses her apprehensions while Princess Bubblegum makes some tea with her Tea robot. Bubblegum then tells her that the Ice King is not a major threat and with science on their side, they have the advantage. Lady and Bubblegum then fly off into the Black Ice Cave where she can't get any signal on her GPS and relies on her heart signature machine where three heart signatures are detected, thought to be Finn, Jake, and Ice King. She also sees several hearts on the monitor, but dismisses them. They both go into a realm where they are attacked by an army of evil hands. They escape, and Bubblegum hears the Ice Kings voice through an air vent. Bubblegum tells Lady to proceed, using the heart signatures as navigation. They are nearly crushed by an enormous tongue, and Lady flies into another room. Much to their surprise, giant eyes on the wall open and shoot laser beams. Lady is hit and badly injured, unable to fly.

Bubblegum carries Lady into a dark passageway. After noticing that she is near Finn and Jake, she finds Ice King on the floor, with a hole in his chest and what seem to be veins spread on the floor. Bubblegum then drops the heart monitor in surprise as Ricardio reveals himself to be the real culprit. He throws Finn and Jake on the ground in front of Bubblegum, who are poisoned by Zanoits. Ricardio reveals that he had spent his time in Ice King's body using his tissue to make his new body. He then recalls on how he only wanted Bubblegum's heart last time, and this time, he wants "the whole package." Ricardio takes Lady from Princess Bubblegum and ties Lady in a knot, throwing her in a corner after that. Ricardio then leans against the princess and asks her to marry him. Bubblegum agrees to marry him if Ricardio can beat her in a hand-to-hand combat. Bubblegum angrily dismisses Ricardio's advances and then tears his limbs apart. She kicks him in the face and warns him to never return. Ricardio escapes into the shadows.

Two days (and another day for the antidote) later, Finn, Jake, Ice King, and Lady Rainicorn are healed, in the Candy Kingdom's Castle's Hospital. Finn wakes up, freaks out that Ricardio has returned and is in the black ice cave. Princess Bubblegum tells Finn that everything was taken care of and shows Finn and Jake that she made a new heart for Ice King out of Ricardio's sinews, toffee and maracas. She walks over to Lady Rainicorn and apologizes for putting her through danger, saying that she "saw it [the five small dots next to Lady's] on the heart monitor" and she "didn't know." The episode ends with Lady tearfully saying "I am pregnant!" in English to a surprised Jake. He responds, "I'm-- puppies?!"

Trivia

 * There's a difference between the noodle that Lady Rainicorn had taken in the episode and the storyboard. On page 15 of the storyboard she says "vermicelli," which is a kind of spaghetti. But in the episode, she says "Vietnamese" (월남 [Worl-Nam] (越南, Korean pronunciation of Chinese-written name of Vietnam)). It is either a translation error or an intended change.
 * There's also a difference in how long "it's been... since Finn and Jake disappeared while battling the Ice King." On page 23 of the storyboard Princess Bubblegum says "three days"; in the episode she says "three weeks."
 * This is the first episode where Princess Bubblegum and Lady Rainicorn are the main characters.
 * This is the first time Princess Bubblegum was seen fighting in hand to hand combat.
 * Lady Rainicorn speaks English without using a Universal Translator for the first time.

 * On the title card, Finn and Jake's faces are crossed out of all of the pictures.

Episode connections

 * When Princess Bubblegum says "I know a thing or two about building a body out of bio-mass" while fighting Ricardio, it is a reference to her creation of Goliad, the Earl of Lemongrab, Stormo and reverting herself back to her eighteen-year-old self in "Too Young."

 * Zanoits, which were first mentioned in "Ricardio the Heart Guy," are used to poison Finn and Jake.

Cultural references

Storyline analysis

 * In the beginning, when Princess Bubblegum used her heart signature machine to locate Finn and Jake, there were two regular-sized heart signatures on the screen (Lady Rainicorn and herself), but five additional ones near one of the regular heart signatures, indicating that Lady Rainicorn has five unborn children.
