Daddy's Little Monster

"Daddy's Little Monster" is the sixth episode in the fourth season of Adventure Time.

Synopsis
Finn and Jake attempt to rescue Marceline and find out what's making her behave so strangely. Part 2 of a two-part episode along with "Return to the Nightosphere."

Plot
The episode begins where Part 1 left off, with BMO charging Jake's video phone. The phone is finally charged and Finn and Jake watch a video of their time in the Nightosphere. There are three videos on the phone. The first one shows Finn and Jake entering the Nightosphere to hang out with Marceline. The second shows them playing music. Marceline's dad flies in abruptly to tell Marceline that he wishes for her to take over the family business and rule the Nightosphere with his evil amulet that can grant anyone's most evil wishes. Though Marceline refuses, claiming that she has her own plans for life, she tries it on and accidentally turns herself into an evil monster like her dad. The video blacks out as a third video comes on, showing how Finn and Jake got thrown in their jail cell by the Nightosphere Jailer, who was cursed to spew bananas from his ears by Marceline.

They decide to return to the Nightosphere to save her. After disguising themselves as demons, with Finn using a cut-up paper plate and Jake using his stretching powers, they go back using the spell that Marceline used to (accidentally) enter the Nightosphere in "It Came from the Nightosphere." When they re-enter, they find themselves trapped in yet another line, but one which leads to Marceline, who is playing cruel tricks on the demons of the Nightosphere. They are discovered by Marceline when they try to cut in line, and barely escape after she attempts to eat them. They run into her house and find the Lord of Evil making a sandwich. He explains to them that he only wanted Marceline to follow in his footsteps and that he thinks it's great she has been possessed by the amulet. Hearing this, Finn gets angry and slaps the Lord of Evil's sandwich out of his hands and goes back to rescue Marceline.

Finn and Jake decide they need a way to get close to Marceline and start a political rap. Soon, other demons join them in the revolution to overthrow Marceline. They reach Marceline and finally get to take off the amulet that was controlling her. However, Jake isn't able to go back to the portal they created before as the demons try to eat his legs, disabling him. So Finn puts on the amulet and throws Jake and Marceline out of the Nightosphere. Unfortunately, under the control of the amulet, he tries to get Jake and Marceline back to the Nightosphere as he has become evil, but the Lord of Evil rips the amulet off of Finn and puts it back on, explaining to Marceline that he is proud of her no matter what she does, and that he likes her friends (Finn and Jake). Marceline closes the Nightosphere portal and after stating her surprise at her dad for liking Finn and Jake, she jokingly says she doesn't want to hang out with them anymore. The episode ends with Marceline asking Finn if he's alright. Finn is exhausted, however, after having been under the control of the amulet and ignores what she's saying.

Trivia

 * This is the fourth time Finn loses his humanity. The first was in "Trouble in Lumpy Space," the second time was in "Crystals Have Power," and the third time was in "Wizard Battle."
 * This the second time he loses his "purity", the first being in "City of Thieves."
 * Further reference to the Mushroom War is found in the form of magnetic tourist plates stuck onto Hunson Abadeer's kitchen cabinets. The plates are from Las Vegas, Orlando, and Arizona.
 * When Jake is panning over the Nightosphere with his video phone, he says "This place is bananas," adding to the two-part episode's exhaustive list of banana gags.
 * Since the airing of these two episodes on April 30th, Marceline & Hunson Abadeer havent made any further appearances.

Cultural references

 * The "Goggle Hands" Finn makes when speaking to Marceline may be a reference to the movie Troll 2.
 * One of the demons in the Nightosphere greatly resembles The White spy in MAD.
 * Finn with the amulet resembles the fictitious entity Slender man.
 * Art styles resemble The Beatles: Yellow Submarine.

Episode connections

 * Finn uses the spell he learned in "It Came from the Nightosphere" to open the gate to the Nightosphere.
 * The title card shows Finn and Jake as bananas. This is a reference to the running joke involving bananas in both episodes.
 * The Phil Face makes a return, with Finn drawing it on the wall of the tree house in order to open a portal to the Nightosphere.

Errors

 * In the beginning of the episode, when Marceline came through the portal, her fangs were blunt, instead of sharp, like they are regularly.
 * At the last part of the episode, Marceline's bite mark was mistakenly located at her right part of her neck. Also...the bite mark is initially missing, then it appears briefly on the right side, then it disappears again.
 * When Hunson makes his sandwich, there is a bite mark in it just before he has a bite. Also, there is already mustard on two layers of the sandwich prior to Hunson even pulling out the mustard bottle from the refrigerator. He may have done the sandwich "build" at the refrigerator.
 * Jake's Video Phone switches back and forth from low and high power while they are watching the videos. It's possible that it got damaged in the Nightosphere, however, and may be malfunctioning..
 * In "Return to the Nightosphere," Finn and Jake both pop out of the bananas together, but in "Daddy's Little Monster," Finn is tossed into the bananas while Jake is tossed next to them.
 * Both Hunson and Marceline have similar, red cowboy boots. There is a design flaw in the upper boot shafts on both pairs. The upper shaft dip in cowboy boots are front-to-back...not side-to-side (can't walk/sit comfortably and boot shafts will be ruined if dips are side-to-side).
 * The amulet is literally ripped right off of two necks (once from Marceline's and again from Finn's), but the chain or rope that the amulet is on miraculously remains intact both times.
 * When Hunson gave Marceline the amulet, only one of her fangs appeared while the other was missing. Shortly later it reappeared again.
 * When the 3rd video starts Finn and Jake are sitting on the floor in the living room in front of the purple upholstered couch next to the gramophone. When the video ends they are still sitting on the floor, but in front of the wooden bench in the kitchen.

Storyline analysis

 * It seems that Hunson seems to enjoy bug milk, as he is seen drinking it from a carton. This may be why it is needed in the ritual for opening the Nightosphere portal.
 * Finn and Jake might have suffered Retrograded Amnesia when Marceline knocked down Finn and Jake that is the reason why they forgot how they got to the Nightosphere. Jake also cries, "Ow! My hippocampus!" as he falls, which is the part of the brain that is responsible for short- and long-term memory.
