Finn and Jake awaken in the depths of the Nightosphere, and try to find out how they got there and how they can escape.
Tropes
- Cool and Unusual Punishment: One of the major torments of the Nightsophere involves the tedium of waiting in a massive line for favors from the ruler.
- Fantastic Drug: Jake wonders if their predicament was caused by drinking too much "juice of the elder toad".
- Fire and Brimstone Hell: The Nightosphere is full of this sort of imagery.
- Funny Background Event: A portrait depicts Hunson Abadeer going golfing with Peppermint Butler. There's also a portrait of Abraham Lincoln.
- Heroic BSoD: Poor Finn has a brief one after seeing the massive line to see the Ruler of the Nightosphere just leads to another massive line, where he collapses to the ground while groaning in despair.
- Hope Spot: After literally weeks of waiting in line in the Nightosphere to see its ruler, Finn and Jake get to the end of the line and are told to Take a Number. Finn is excited to see he and Jake are next in line, and goes through the door... to find another queue that's almost as big as the one they just left.
- Ironic Echo: Two lines said by Marceline, in the span of seconds: "No one leaves the Nightosphere!" and "You're forbidden to come back to the Nightosphere!"
- Number of the Beast: Finn and Jake spend 666 hours waiting in line to get to Hunson Aberdeer (27 days and 18 hours).
- Right on Queue: There's a line to see the Lord of the Nightosphere that's so long, and moves so slowly, it takes days for Finn and Jake to get to the end. Then that turns out to lead to another line.
- Satanic Archetype: Hunson is confirmed to be this in this episode, being the ruler of the Land of Ooo's equivalent to Hell/the Underworld.
- Sequel Episode: To "It Came From The Nightosphere" going into more detail about this dimension.
- Shout-Out:
- The visuals of the Nightosphere and the demon designs are derived from the artwork of Hieronymus Bosch.
- The demon rowing a boat on the heads of the demons in the queue is based on the damned Phlegyas ferrying Dante across the River Styx in The Divine Comedy.
- Two-Part Episode: With "Daddy's Little Monster".
- Wham Shot: Finn stabs what he thinks is Hunson Abadeer in the head... only for Marceline to come out and tell the boys to go back to the mortal realm and not come back to the Nightosphere.
- What Did I Do Last Night?: The episode opens with Finn and Jake waking up locked in a cage in the depths of the Nightosphere, half-buried in a pile of bananas, with no memory of how they got there.
