Slumber Party Panic

Synopsis
After Princess Bubblegum's experiment to revive dead candy people with her decorpsinator, it goes horribly wrong. Finn is then assigned to protect the people of the Candy Kingdom until she can devise a cure.

Plot
Finn and Princess Bubblegum are in the Graveyard doing a science experiment, and Jake and Lady Rainicorn are playing in the forest. Finn and the princess try to bring dead candy people back to life. She tests her Decorpsinator Serum on the dead Mr. Cream Puff. But instead of actually being brought back to life, he turns into a zombie who craves for sugar. Mr. Cream Puff then spills the serum all over the graves of the dead candy people, and they rise as zombies as well. Princess Bubblegum tells Finn that the Candy Zombies will go to the Candy Kingdom as they crave for sugar and the candy people are made of sugar.

They summon all of the candy people to the candy foyer, where she announces that they are all going to have a slumber party. She tells Finn that if the candy people know about the zombies, they would flip out and explode. (Although they don't explode in later episodes when they become afraid.) During that time Starchy searches for Princess Bubblegum to give her a bigger corpse shovel. He waits for her in the graveyard and finds a candy zombie craving for sugar. Starchy then freaks out and explodes. Back at the Candy Kingdom, Bubblegum makes Finn royal promise not to tell anyone about the candy zombies, then gives him orders to keep them distracted while she tries to finish the serum in her lab. Jake hears part of the discussion and begins asking what Princess Bubblegum and Finn were up to. But because he royal promised Princess Bubblegum not to tell anyone about what's going on, Finn keeps making up lies and tries playing Truth Or Dare, where Chocoberry dares Mr. Cupcake to take off his wrapper. Cupcake then asks Jake whether he prefers chocolate or fudge. Jake says he can't eat either because he's a dog, and if he eats either, he would probably die. But he says if he could eat it, he would choose fudge or chocolate. Finally Jake dares Finn to tell the truth about what's going on.

Finn tries to dodge Jake's question by starting a game of Dodge Socks, but when he throws his sock, Jake smells Mr. Cream Puff's scent on it, because Finn kicked the zombie Mr. Cream Puff when he attacked Princess Bubblegum earlier. To make sure Jake doesn't find out about the zombies, he gets Jake to play Seven Minutes in Heaven with Lady Rainicorn. Meanwhile the zombies have arrived, and Finn tries to keep the candy people ignorant by drowning out the zombies' noises with loud music and barricading all the exits and windows. Then Finn gets the candy people to help him keep the zombies out of the castle by making up a game called Blockado, "the game of barricades". Knowing the blockades won't last long, Finn gets another idea when he takes a look at Manfried the talking piñata. He tells the candy people that they're gonna smash piñatas (not Manfried). Finn blindfolds them so they do not see that the piñatas are really zombies breaking into the castle. Soon they beat up all the zombies and start eating the candy that was stashed in them.

Jake and Lady Rainicorn come out of the closet and sees all the dead candy zombies. When Finn tells him what happened, time suddenly stops. The only people who are not frozen are Finn and Princess Bubblegum, who hasn't finished her equation yet. Suddenly, two Guardians of the Royal Promise arrive and grab Finn and Bubblegum. For breaking his royal promise, the guardians plan to punish Finn with a trial by fire, but since Bubblegum cares for Finn, they decide to make him solve math questions instead. Finn is terrible at math, and at first he is given a really difficult math problem, but luckily one of the Guardians changes it to 2+2. Finn answers correctly and the Guardians reset time. Bubblegum realizes that 4 is the last figure she needs to perfect her decorpsinator serum, as she was too smart to see such a simple answer. Finn and Bubblegum bring the zombies back to life, including Starchy, and the candy people reunite with their former dead relatives. Jake tells Finn that he should have just told him that he'd made a royal promise to not tell about the zombies. Finn promises Bubblegum to keep his promises from now on, and Starchy (despite not being a zombie anymore), craves for flesh and bites Finn's leg. Finn squeezes him, and Starchy farts.

Trivia

 * It is revealed in this episode that Lady Rainicorn speaks Korean, not the gurgling language as in the Animated Short.
 * One of the ingredients in Princess Bubblegum's decorpsinator serum was "explosive diarrhea."
 * Princess Bubblegum's laboratory has a miniature version of one of the Guardians of the Royal Promise.
 * A zombie Finn can be seen in this episode. It was either an easter egg, or a joke, and it does not have anything to do with the plot.
 * When Jake and Lady Rainicorn's time in "7 Minutes in Heaven" are up, Jake comes out eating what looks to be a jelly doughnut. It is unknown how he obtained it.
 * When Princess Bubblegum found out the correct answer so her decorpsinator serum would be successful, pink bubbles can be seen appearing out of nowhere.

Cultural references

 * When the first candy zombie tries to bite Princess Bubblegum, it says "Gimme some sugar, baby," quoting Bruce Campbell's character from Army of Darkness.

Episode connections

 * A season three sequel called "From Bad to Worse" was aired in 2011 as a Halloween special. Pen Ward has stated in an interview that the zombies will return in a future episode.

Errors

 * It appears as if Manfried was not blindfolded during the "piñata smashing" and saw the entire zombie situation, so he knew about it. Finn completely overlooks this.
 * Princess Bubblegum said the decorpsinator would turn the corpses into young and healthy people even though some candy people stayed old like the Candy Corn Grandma.
 * In a "Truth or Dare" game, Jake says that that chocolate or fudge will kill him, but in later episodes, he is seen eating chocolate. The creators stress Jake's use of the word "probably".
 * Starchy had exploded in the graveyard, but in one scene, he could be seen with all of the other Candy People
 * While zombies where comeing through the window, in the corner there was a zombie version of Finn even though he was inside and wasn`t bitten.

Production notes

 * This episode, along with "Trouble in Lumpy Space," aired as the series' "official premiere."
 * In its original broadcast on April 5, 2010, the episode was watched by 2.497 million viewers.
 * The episode was originally titled "The Royal Promise" and later "Slumber Party Slaughter."
