What Have You Done?

Synopsis
Finn and Jake capture Ice King under order of Princess Bubblegum without even knowing what he has done wrong.

Plot
Finn and Jake are seen in the Ice Kingdom at night, trying to avoid some Guard Penguins wielding Ice Axes. Finn says that their secret mission to capture the Ice King is underway, and then says he probably shouldn't say that stuff out loud. The Ice King is seen in his depressed mode playing with a heart puzzle on his bed. Finn rings Ice King's doorbell and Ice King appears to confront the guest. At first Ice King tries zapping, but then realizes no one is there. He notices that a small can of peanut brittle was left on his doorstep. Ice King opens the can and suddenly, Jake springs out of the can and grab his crown. Ice King attempts to shoot them but he is unable to, because his crown has all his powers in it. Finn yells out wrap attack and ties up Ice King with a rope. Jake asks why they did this again, and Finn says Princess Bubblegum explained it all, but was not very precise. They return with Ice King to the Candy Kingdom, which seems to be deserted. Princess Bubblegum arrives wearing a plague doctor mask and spraying a green fog everywhere. She takes them to a wall with a face on it and the face asks for the password. Bubblegum then pinches the face's cheek, and the wall suddenly turns into a door.

Princess Bubblegum says that the door leads to the dungeon where they would put the Ice King. Before Princess Bubblegum can have a chance to explain what exactly it was that Ice King did, she is called to the Grand Hall by Manfreid. Finn and Jake decide to guard the Ice King until she returns. Finn and Jake throw Ice King in a jail cell, with only two bars, but then add more. Jake looks at Ice King's crown and says it was probably stolen, but Ice King states that he made it with the magic that he stole. Ice King begins to tell the two that he is innocent, and that he hasn't committed a recent crime in a while and didn't deserve to be here. But Jake says that he's a jerk and should stay in jail. Then Ice King shows them a mirror (which was broken repeatedly after Ice King accidentally slammed it on the ground) explaining that they were the true jerks and they deserved to be in jail. Finally, Finn is convinced and decides to let Ice King go. At first Ice King thinks it is a trick, but later decides to go along with it.

Finn and Jake state that since they're the bad guys this time, they have to go to jail. Ice King gets his crown, opens a magic door, and escapes. Princess Bubblegum then walks into the dungeon and puts on a pair of pink gloves for interrogation. But when she turns around and sees Finn and Jake in jail, she gets irritated when Finn tells her that they let Ice King go. The Princess takes the two to the grand hall where they see all the candy people lying in beds embedded in ice. Princess Bubblegum explains that Ice King kind of did this and kind of didn't. 3 days ago, the Ice King wanted to show off his new trick to the princess by making snow from his beard but everyone became infected with Freezer Burn Flu. Princess Bubblegum said Ice King didn't mean to cause the disease, and she learned that the only way to cure it was to obtain the "sad howls" of Ice King himself. But, when she begged to Ice King to help, he thought she was hitting on him. So she knew the only way to take the Ice King's howls was by force, that's why she told Finn and Jake to capture him. But Finn says he just can't beat people up for nothing because it's against his alignment, but he promises he'll find a way to save the Candy Kingdom. Princess Bubblegum thanks him, but she almost bursts into tears under all of the stress, so Finn calms her. Then Finn and Jake head back to the Ice King's Castle to obtain the howls.

When Finn and Jake enter, Ice King comes out and asks if they want to participate in game night, because he now thinks that Finn and Jake are his best friends for letting him go. But when Finn tells Ice King to howl, he says he couldn't possibly howl without giggling. Ice King walks over to Finn and says that there was a bug on him, which in reality was just Jake, only smaller. Ice King hits Finn, wanting him to get the "bug" off. Finn gets an idea on this and pretends he is dead. Showing guilt, Ice King picks up Finn's body and howls extremely loud. His howls reach all the way to the Candy Kingdom, curing all of the inhabitants. When Princess Bubblegum sees that her people are getting healthy, she faints of happiness. Ice King then drops Finn and walks away. Finn says that was a mean thing to do and Jake says that if he came across Finn's lifeless body he would "clasp him dramatically for a kajillion years." Finn then plays dead and Jake carries him and wails back to the Candy Kingdom.

Trivia

 * When Princess Bubblegum is researching the cure involving the pained howls of the Ice King, the number 5318008 appears on one of the book's pages. Using calculator spelling, that number spells out the word "boobies."
 * As written in the storyboard, the password that Princess Bubblegum uses to gain entrance to the dungeon is "ttublaw." Reversed, it's "walbutt."
 * Princess Bubblegum said, in German, "Ich bin so glücklich! Ich könnte... Ich könnte..." (in English: "I'm so happy! I could... I could...") and passes out before she could finish.

Errors

 * While Ice King was flying away from the Candy Kingdom, his eyes appear as black dots instead of white eyes.

Cultural references

 * The fumigation suit the Princess is wearing is modeled after a plague doctor costume, which was worn by doctors during the Black Death. Although, being Princess Bubblegum, the typical black was changed to pink.
 * There are several more references to Dungeons &amp; Dragons in this episode. Ice King casts "Detect Secret Doors" when leaving the dungeon, a classic spell from the game. At one point Finn says that keeping the Ice King captive is against his alignment, which is a morality system in the game.
 * The box that contains the Ice King's board game reads, "Poots and Bladders," a play off of the game "Chutes and Ladders."

Production notes

 * This episode was previously titled "Ice King Has a Point." The Frederator blog reported that "Ice King Has a Point" had the production code 692-027, replacing a canceled episode with production code 692-006.

Storyline analysis

 * Princess Bubblegum's medicine book depicts Ice King's wails of pain directed to possible candy people, implying that Freezer Burn Flu has happened before.
 * The Ice King claimed he got his crown with the power he stole. This is later proved wrong in "Holly Jolly Secrets Part II," when Simon Petrikov states that he purchased the crown.
