From Bad to Worse

"From Bad to Worse" is the thirteenth episode in season three of Adventure Time.

Synopsis
When another plague of Candy Zombies arises and Princess Bubblegum is among the undead, Finn and his friends are in a race against time to figure out how to stop it...but things get worse by the minute.

Plot
The episode begins with Finn, Jake, Lady Rainicorn, and Lumpy Space Princess running from Candy Zombies and just barely escaping to the Castle in the Candy Kingdom. They see Princess Bubblegum, and are informed that while she was experimenting with candy zombie tissue, Cinnamon Bun ate it out of hunger and then infected the entire Candy Kingdom while Princess Bubblegum escaped.

Princess Bubblegum then says that she is coming up with a cure, but a candy zombie bursts through the window and bites her on the shoulder. She tells Finn to use Science but, before she can explain, she is dragged out of the window and turns into another zombie. All she could manage to say was: "Science is... MUH RAAHH." Lumpy Space Princess then pushes Finn away from the window and, much to Finn's horror,hits zombie PB with a hammer and nails a board to the window. Finn then says they will have to make their own formulas to cure her and the Candy Kingdom. Finn tests his cure on a candy zombie but with horrible results. The candy zombie grows wings and infects the other zombies with the same liquid giving them wings as well.

There is a view of Starchy on top of a building stating he's glad he's not down there with all the zombies and starts to do a little dance, but is grabbed by Pineapple Guy and thrown into the window and breaks through the wood.

Finn and the rest of the group escape to the top of the castle to continue to try and cure the zombies. Lumpy Space Princess then drops her formula on to some of the zombies, but it does nothing but give them enlarged lips. LSP wants this to happen to her, goes outside to lick it up, and ends up getting turned into a zombie herself. Jake and Lady Rainicorn then test their formula, but it only makes the zombies stronger. The candy zombies use their new abilities to reach the top of the castle and attempt to bite the group, so they retreat to the lab. The zombie Candy Cane Guy comes out from hiding in the lab and bites Jake, who uses his Stretchy Powers to prolong the effects. However, Jake realizes he will become a zombie, so he goes into a sealed science shower. Lady Rainicorn feels sorry for him, and lets Jake out, only to be bitten. Then, the candy zombies break through to the lab, and Finn locks himself in the science shower. He then realizes that Science is Princess Bubblegum's rat. Science creates the antidote and Finn tests it on Jake, discovering that it works, but then Jake gets attacked by the mob of Candy zombies that were standing by him. Finn covers himself with the antidote, and the crowd of zombies break into the science shower.

It cuts to all the candy people back to normal, and we see Princess Bubblegum awarding Science with a medal. It ends with Princess Bubblegum yelling rejoice three times to the cheering Candy People.

Trivia

 * Along with "The Creeps," this episode aired as part of Cartoon Network's 2011 Halloween programming event.
 * This episode involves the candy zombie plague that first appeared in "Slumber Party Panic".
 * A few minutes of this episode were previewed at the Adventure Time/Regular Show panel at New York Comic Con 2011.
 * This is the third time Lady Rainicorn calls a character by name. In "Video Makers," she calls Jake while using Korean, pronouncing his name as close to English pronunciation. In "The Creeps," She refers to Jake; pronouncing like a transliterated name into Korean. However, in this episode, she uses a perfect English pronunciation to call Jake.
 * This is the first time where Lady Rainicorn is referred to as "L.R." by Finn.
 * The sticker on Science's cage is a reference to the AMC televised version of "The Walking Dead."
 * Finn was the only one to escape being turned into a zombie. Ironically, a zombie version of him made a thumb|300px|right|Animaticshort appearance in "Slumber Party Panic" in the middle of the candy zombies.
 * This is the second episode where Finn mistook what PB said with one of her pet's name, the first being "Death in Bloom," where he misunderstood the name of The Morrow.
 * When Princess Bubblegum said "Science is Maahraah" she was trying to say " Science is my rat."
 * Oddly, Princess Bubblegum was far away from the windows before her flashback started, but after the flashback she was near the windows.
 * Finn trapping himself in the glass-doored "safety shower" could be a reference to the ending of the movie I Am Legend with Will Smith.
 * When Jake is bitten again, he does not get lips, wings, or muscles.
 * When Jake pushes Candy Cane Guy into the locker, he has nothing but a zombie infection. Yet, when he escapes due to the sudden attack of zombies, he can be seen with strong-arms. This might be because Jake probably had some of his fomula on his hands. But, yet again, not a few seconds later in another scene, he has normal arms. This adds to the confusion of Jake not recieving any other deformities.
 * The plague is caused by Cinnamon Bun eating the zombie flesh, however, in "Slumber Party Panic," when the Candy People ate the candy from inside the zombies, they were unaffected. (This may be becasue he was only eating the flesh. In "Slumber Party Panic," what came out of them seemed to be uninfected, hence the fact that the candy people didn't turn into zombies when they ate it.)
 * Even though the antidote in " Slumber Party Panic ," was orange. The antidote in this episode was yellow.
 * When Finn finished his formula, the flask was round and the liquid was blue. Throughout the rest of the episode, the flask was triangular and the liquid was a yellowish color.
 * Technically, if the zombies just wanted sugar, they wouldn't have bitten LSP, Lady Rainicorn, and Jake.
 * The music on the record that Science plays is similar to that of the "Jepardy" theme music.
 * In PB's flashback, there is a laser pointed at a chair and a pile of bones.
 * Beacause LSP is "lumpy", when her lips become plumper, they also become lumpy.
 * The only time a full zombie transformation appears onscreen is when Jake is bitten for the second time, which is ironically, the last zombie transformation.
