Too Young

"Too Young" is the fifth episode of season three of Adventure Time.

Synopsis
The Earl of Lemongrab takes over the Candy Kingdom due to Princess Bubblegum's age regression, forcing her and Finn to try and get rid of him even if it means a life-altering decision.

Plot
In the begining of the episode, Finn is in the Candy Kingdom on a "date" with 13-year-old Princess Bubblegum. Finn gets a call from Jake, who is at the Tree Fort playing a game on Beemo. Jake gives Finn some advice for his date and then hangs up to play the video game. Princess Bubblegum asks Finn to test a potion she has been working on that is meant to give the user a shower by turning their sweat into a soap. However, it ends up being unbearably spicy. Afterwards, Manfried announces the arrival of Lemongrab who asserts that he will take control of the Candy Kingdom until the princess turns 18 again because she is "too young" and he is older than her. Lemongrab apparently has this right. Being the creation of Princess Bubblegum from a failed experiment, he assumes the right as the next heir of the throne. A highstrung, strict, and true to his name and shape, sour individual, he sentences members of the castle staff to the dungeon with little to no provocation. Finn and PB attempt a series of pranks to make him leave; making an intricate machine that lowers a namecalling sign and hitting him while disguised as ghosts. With Lemongrab not showing any signs of wanting to leave they scheme their final prank, dripping the spicy potion from earlier into his meal and into whatever he tries to soothe the burning with. However, the plan backfires and results in Lemongrab sending all the staff of the Candy Castle to the dungeon, including Finn and PB. Reluctantly, she realizes the only way to get Lemongrab out is to become 18 again and take back the throne, despite enjoying being a kid again. PB conveys that she needs candy "biomass" to increase her size back to that of 18. The Candy People pitch in and offer parts of themselves. Finn provides the "binding agent" with his saliva. Finishing the process, Finn catalyzes the pieces with the warmth of a "love hug". Just before PB transforms, they share a brief kiss. At 18 again, PB kicks Lemongrab out of the kingdom and reclaims her throne. In the end, Finn asks her for another hug, but she reminds him that that was "five years ago". Finn calls Jake, who comforts him with advice conceived from his exploits from the videogame he was playing, saying:
 * "It's not easy, but you have to be persistent. You might have to defeat a demon lord, or warp through several worlds. But once you do, you walk up the wizard stairs, and produce your magic key you got in the water world and unlock the chamber door. Then, you walk right up to the princess, and give her a smooch. ...Does that make sense?"

The episode ends with Finn looking up to see a distant Princess Bubblegum in a high tower, hair blowing in the wind.

Trivia

 * This episode marks Princess Bubblegum's first appearance in Season 3, making this the first (and only) full episode in her 13-year old form since the events of "Mortal Recoil".
 * Princess Bubblegum reverts back to her old 18 year old self in this episode- it is revealed when she says "That was like, 5 years ago!" (13+5=18).
 * Princess Bubblegum's prank involves a Rube Goldberg machine, including pixies, ketchup, and even a Phil Face.
 * The seconed prank involved Finn and Princess Bubblegum dressing up as ghosts and then Finn hitting Lemngrab in the stomach.
 * This is the first time Princess Bubblegum and Finn kiss on the lips.
 * The video game that Jake played is similar to a Mario Brothers and a Legend of Zelda game, where the player must travel through different worlds to find the key to the castle and save the princess. The blocks on the castle resemble brick blocks. And the keys have great similarites to the ones in The Legend of Zelda.
 * This is the third time that Jake is not a main character.
