Daddy's Little Monster

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

Synopsis
Finn and Jake attempt to rescue Marceline and find out what's making her behave so strangely. Part 2 of two-part episode.

Plot
The episode begins where Part 1 leaves off with Beemo charging Jake's video phone. The phone is finally charged and Finn and Jake watch a video of them in the Nightosphere. There are three videos, the first video shows Finn and Jake going into the Nightosphere to hang out with Marceline, then the next video loads as it shows them playing music when Marceline's dad suddenly comes in and tells Marceline he wants 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, but 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 have bananas come out of his ears by Marceline.

They decide to return to the Nightosphere to save her. After disguising themselves as demons, Finn using a paper plate and Jake using his stretching powers, Finn and Jake go back using the spell that Marceline used to (accidentally) enter the Nightosphere in It Came from the Nightosphere. When they go back inside, they find themselves trapped in yet another line, but leads to Marceline, who is playing cruel tricks on the demons of the Nightosphere. They are discovered by Marceline when they try to cut the line, and they barely escape after she tries 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 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 help them. 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 and explains to Marceline that he is proud of her no matter what she does, and that he likes her friends. Marceline closes the Nightosphere portal and says she won't hang out with Finn and Jake anymore. The episode ends as Marceline asks Finn if he is okay, shivering after having been under the control of the amulet, ignoring what she was saying.
