Wake Up

"Wake Up" is the first episode in the sixth season of Adventure Time. It is the one hundred and fifty-seventh episode overall.

Synopsis
In order to find Finn's father, Finn and Jake must commit a cosmic crime...unless the Lich beats them to it.

Plot
Finn and Jake decide to go to Prismo for advice on how to find Finn's long-lost father. Finn and Jake talk to Prismo at a party he is hosting with The Cosmic Owl, Death, Peppermint Butler, and Party God. Peppermint Butler asks Prismo if it is safe to be taking "selfies" with an unconscious Lich, to which Prismo replies that ever since he wished for all life to be destroyed, The Lich had been in a paralyzed state. Jake begins to panic when Prismo runs out of cheese crackers, but Prismo creates more.

Jake begins to talk to Prismo about the Citadel, he says that since he and Finn had used their wishes he brought Shelby along to make the wish for him, but Shelby wishes for a pony for his girlfriend instead. Prismo explains that you cannot wish yourself into the Citadel. Prismo tells Finn that to gain access to the Citadel, one must commit a "cosmic crime," and to do so, all Finn needs to do was to bring a sleeping old man to Prismo's dimension, without waking him up. Prismo gives Finn and Jake pen-lights. Finn and Jake then set out to find the sleeping man which Prismo said was located on a rock that looked like an upside-down duck.

Once they reach the rock, Finn and Jake take the old man and his bed back to Prismo's dimension, but on the way the old man begins emitting strange black beings that can be vanquished by the light of the pen-lights. Upon arriving, Prismo comments that he wanted to see himself before they wake the man up, puzzling Finn and Jake.

Prismo explains that he is nothing more than the manifestation of a dream being had by the old man. He then says that if the man had woken up, Prismo would cease to exist, until the man fell back asleep in 1000 years. And also that killing him would be a "cosmic crime" capable of sending them to the Citadel.

After reassuring Finn and Jake, Prismo tells them to wake the man, but before they can, The Lich springs to life and grabs the old man, waking him. Prismo disappears, and then the Lich blows toxic gas into the old man's nose, turning him into dust. This causes Jake to becomes enraged at his friend's death. Before Jake can act, a Citadel Guardian imprisons the Lich in a crystal cell and takes him away, but not before Finn chases after the Lich.
