Plot
Finn and Jake are seen in the Ice Kingdom at night, while trying to avoid some guard penguins with Ice axes. Finn says that their secret mission to capture the Ice King is underway, though he then says he probably shouldn't say that stuff out loud. They ring Ice Kings doorbell and Ice King appears. At first Ice King tries zapping but then notices no one is there. He notices a small can left on his doorstep that is peanut brittle. Ice King opens the can but suddenly, Finn and Jake spring out of the can and grab his crown. Ice King attempts to shoot them but he can not since 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 back to the Candy Kingdom, witch seems deserted and gloomy. Princess Bubblegum arrives wearing a gas mask and spraying a green fog everywhere. She takes them to a wall with a face on it. The face asks for the password and Bubblegum pinches the faces cheek. The wall suddenly turns into a door. Princess Bubblegum says that the door leaded to the dungeon where they would put the Ice King in. Before Princess Bubblegum can have a chance to explain what bad thing Ice King did, she is needed in the grand hall. Finn and Jake decide to guard the Ice King till she returned. Down in the dungeon, Finn and Jake throw Ice King in a jail cell with only two bars, but then fix it with more. Jake is looking at Ice Kings crown and says it was stolen but Ice King states that he maid that item with the magic that he stole. Ice King begins to tell the two that he is innocent and didn't deserve to be here. Jake says that he is a jerk and should stay in jail but Ice King shows them a mirror of them selves(witch constantly broke after Ice King accidently 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 then decides to go along with it. Finn and Jake state since there the bad guys this tim that they have to go to jail. Ice King gets his crown and opens a magic door and escapes. Princess Bubblegum then walks in but sees Finn and Jake in jail. She gets mad when Finn tells here that they let Ice King go. The princess takes the two to the grand hall and they see all the candy people lying in beds embed in ice. Princess Bubblegum explains that Ice King kinda did this and kinda not. Ice King had made snow in the candy kingdom with his beard and everyone was infected by this, witch was called freezer burn flue. Princess said Ice King didn't mean to cause decease and learned that the only way to cure it was to obtain the sad howls of the Ice King himself. But when she begged to Ice King to help, he thought she was hitting on her. So she knew the only way to take the Ice Kings howls was by force. Finn and Jake then go to the Ice Kings castle to give up the howls. When they enter, Ice King comes out and asks if they want to play game night. Ice King now thinks that Finn and Jake are his best friends for letting him go, but when Finn says Ice King needs 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, witch was just Jake only smaller. Ice King hits Finn to get the bug of but Finn pretends he is dead when he gets hit. Ice King picks up Finns body and howls super loud. The howls then reached all the way to the candy kingdom and cured all the people. Ice King then drops Finn and walks away. Finn says that was just mean but says he would carry Finn forever. Finn then plays dead and Jake carries Finns body and pretend screams.

Trivia

 * This episode was released on the Cartoon Network website under the video section a week before it aired on television.
 * There are several more references to Dungeons and Dragons in this episode, namely when Ice King casts "Detect Secret Doors," a classic spell from the game, and Finn saying that keeping the Ice King captive is against his alignment. Alignments were a system used in several editions of Dungeons and Dragons to keep track of a character's morality, such as Good or Evil. The game is also extensively referenced in the episode "Dungeon".
 * When the princess 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".
 * At the end, before the princess faints, she says, "Ich bin so glücklich, ich konnte, ich konnte..." which is German for "I am so happy, I could, I could..."
 * A few more german words. Near after the begining, Princess Bubblegum says: Ich bin heir, Finn. Translated into English, that is "I'm here, Finn".
 * This episode might be based on the canceled episode "Ice King Has a Point" which it replaced, although it's impossible to be certain, as information about that episode has never been released.
 * Ice King makes a reference to Gunter, telling him to dispose of Finn's carcass (Finn faked his death). However, Gunter did not appear in the episode, although the Guard Penguins did.
 * The game piece Ice King carved with his teeth looked like a backround character from Chowder in the episode "Endive's Dirty secret".
