Jake vs. Me-Mow

Synopsis
Me-Mow, a tiny assassin cat, hides in Jake's nose and orders him to kill Wildberry Princess or face death.

Plot
It starts off with Wildberry Princess humming and making meat filled pies for Finn and Jake in her bungalow. As she bends down to place her oven mitt in the drawer, she notices a tiny opening on one of her pies, but disregards it and carries it to the table. Wildberry thanks the two for answering her summons, as she speaks of someone trying to kill her. Although she states that it was 'no big deal', Finn corrects her and says that it is a big deal and demands details. Wildberry complies and goes to a retrieve a note sent by the Guild of Assassins, which was "stabbed to [her] door...man." The note states "Princess Wildberry, we're going to assassinate you. G.O.A." Finn vows that he and Jake will protect her, Jake however continues to gobble on his human pie, by which Finn becomes disgusted and goes outside to continue his conversation with Wildberry Princess.

While Jake remains inside, he eyes Wildberry's pie and begins to consume it. In the middle of the pie, he sees a tiny cat. The tiny cat leaps on his nose and threatens him with a tiny poison syringe, Jake realizes that this is the assassin, who then introduces herself as Me-Mow, a second class assassin. She tells him she will graduate to full membership if she assassinates a princess. Since Jake had blown her cover she orders him to be the one to kill Wildberry Princess. Jake refuses and says he would rather be injected with poison, but with Me-Mow having the poison in hand, Jake retracts his statement and claims he would assassinate the princess. Me-Mow then climbs into Jake's nostril to watch the deed be done and threatened that if Jake tried to trick her, she would poison him.

When Finn and Wildberry return, Jake tries to convince Wildberry Princess being killed wouldn't be so bad, but this only scares her and causes Finn to become suspicious. Jake apologizes and nervously tries to think of an idea. He spots a bag of meat and carries Wildberry's crown to it. He then punches the bag of meat as Me-Mow watches from above. Afterward Jake proclaims that he will carry her to the window, upon reaching the window he lets the bag of meat drop to the ground below. He exclaims that "Wildberry Princess is dead!". The cat is impressed and is about to exit the nostril, when the voices of the berry guards exclaim how happy they are that Wildberry Princess is alive, as they had seen the bag of meat with her crown laying on the ground. Angry at the reveal, Me-Mow injects Jake with half the poison as punishment for tricking her, and says that he will die in thirty minutes unless he kills the princess, in which case she will give him the antidote. Jake tries to tell Finn about the tiny cat, but Me-Mow threatens to inject the rest of the poison in Jake's brain if he said anything further.

Jake's next idea is to have Finn sing their mom's lullaby. Finn is embarrassed to sing the lullaby with an audience but does so. Jake shoves two sausages in his ears as the song lulls Wildberry, the guards and Me-Mow to sleep. Jake frantically tries to tell Finn about the assassination, then attempts to once again tell of the situation by writing out "Cat → Nose" with pie filling. Finn misinterprets this as a request for him to make a cat noise and does so, meowing so loudly that Jake has to toss Finn out the window to keep Me-Mow asleep. As the tiny assassin sleeps in his nostrils she talks about double-crossing Jake after the deed. Jake takes the opportunity to shrink his hand and try to reach the antidote only to have an angry Finn return and question him, waking Me-Mow who injects another shot of poison. Jake tries to defuse the confusing situation by suggesting that they take Wildberry somewhere safer.

The three arrive at a high cliff side and Jake instructs Finn to stand guard facing away from the cliff while he stands beside Wildberry near the ledge. As Wildberry teeters on the edge, Jake's arms are outstretched to push her with Me-Mow encouraging him. At that moment a blue bird flies past and spots the sausage still in Jake's ear and hungrily dives for it only to crash into his head, resulting in Me-Mow tumbling from his nostril and landing in front of Finn's feet. With Me-Mow revealed, Finn now realizes what has been happening and faces the tiny assassin and threatens to kill her if Jake dies, he orders her to hand over the antidote. She refuses and is up to the challenge. Despite the attacks with a tiny dagger, Finn is only amused at the tiny assassin. Me-Mow slices Finn's cheek, but he isn't bothered, saying "You're only making my face look cooler!" She jumps for his eyes, intending to blind him, only to have Finn simply blow her away. She smacks against a tree and is held there with Finn's palm. Finn then asks for Me-Mow's Antidote, but she smashes it and happily tells him that she gave Jake enough poison to kill a dog fifty times his size. The two come to a realization that Jake can stretch his liver fifty-one times the mentioned size and detoxify his body before dying, which he then does. At Finn's inquiry as to Jake's health, Jake makes up an impromptu song: Big Liver. Me-Mow vents her frustration causing her tail to become unkempt, but Wildberry says that she could be a royal pet. Infuriated, Me-Mow responds by leaping at the princess to kill her, but at the last moment the princess pops her berries and Me-Mow soars off the cliff. While Finn compliments her on her defensive ability, Wildberry Princess tells them it is actually a medical condition and she needs to see a hospital. The episode ends with Me-Mow surviving from the fall by flying away on the back of the blue bird.

Trivia

 * This episode was originally named "An Assassin in Jake's Nose."
 * Both the title card and Me-Mow are created by Gunnar Gilmore, a young Adventure Time fan. According to Pendleton Ward, he wanted to include the fan-made character "because it’s so cute and it was drawn by a tiny kid."
 * In the original drawing, Me-Mow doesn't have a tail.
 * Due to Wildberry Princess' house being full of pieces of meat and dead animals, it is possible to conclude that she has a carnivorous diet. This is most likely because if she ate fruit, she'd be eating her own kind.
 * When Jake's hand was inside of his nose, he made it jump with respiration sounds like an astronaut.
 * When Me-Mow injected half of the poison in the syringe in Jake, the bottle was in half, but when Finn was singing, the bottle was full.
 * After Finn finished singing Sleepy Puppies, Jake heard everything Finn said clearly even though there were still sausages in his ears.
 * The method of Jake detoxifying himself is similar to how he ate a broom in the episode "Wizard."
 * By what Me-Mow said, she only discovered that Jake is a magic dog at the end of the episode, which doesn't make sense, since she saw his hand as tiny, inside his nose, while trying to steal the antidote.
 * When Wildberry Princess' guards ran up to tell her they thought she was the one who fell, the guards voices switch. When they first run up to her the purple berry guard has a woman's voice and the pink guard has a male's voice. After a short scene showing Finn and Jake, the voices of the guards switched.
 * This is the only episode where Wildberry Princess is given multiple nicknames.
 * This is the only episode where the title card is a fan-drawing.
 * Me-Mow's tail was pretty thin and long, but when she feels like she's in danger or she's mad, her tail grows short and scruffy, like Cake's tail sensitivity.
 * Somehow Jake knew Me-Mow extended her claws even though he can't see inside his nose.
 * Me-Mow cuts Finn on the leg and on the face with his tiny dagger, but the scratch on his leg disappears and his cut on his face disappears the next face shot, but comes back.
 * Me-Mow size seems to change throughout the episode. She seems small enough to fit in Jake's nose at first, but then she seems almost as big as Finn's hand.
 * Both this episode and "No One Can Hear You," the prior one, are resolved by a deus ex machina. In this case, a bird tries to grab one of the sausages from Jake's ears knocking Me-Mow out of his nose.
 * Wildberry Princess is called "Princess Wildberry" on the note that stated that she'll be assassinated.
