Adventure Time - A Glitch Is a Glitch

About this Adventure Time episode:
Adventure Time - A Glitch Is a Glitch is the 15th episode of Adventure Time season 5.
In this Adventure Time episode, as Finn and Jake are drawing a picture of Ice King on their computer, a brick with a floppy disk taped to it flies in through their window. When they try to read the disk, they find a disturbing video of a woman eating her own hair. Jake tries to exit the video, but it produces a glitch that materializes outside the computer and begins to destroy their treehouse.
Meanwhile, in the Candy Kingdom, the Ice Ki b b nng appears and discusses with Princess Bubblegum a purported statement she made about going on a date with him if he was the last person in Ooo. Finn and Jake arrive and Ice King tells them that he created the virus so that, indeed, he will be the last person around, which will force Bubblegum to go on a date with him. Finn and Jake attempt to save the Candy People, but are dismayed when they keep being "deleted". Finn manages to enter the "Universal Source Code" by breaking a hole in the virus' body. They find the virus, a grotesque digital likeness of Ice King's head, eating pieces of source code, which in turn deletes reality. Before they can reach the virus, Jake's and Finn's limbs are deleted. Meanwhile, Princess Bubblegum attempts to force Ice King to relinquish the anti-virus, only for him to reveal he did not make one.
Back in the Source Code, Finn attempts to slice open the virus but it eats his sword. When all seems lost, Jake remembers the video Ice King sent at the start of the episode, and both he and Finn start eating Finn's hair. Disgusted, the virus regurgitates all the chunks of code it consumed and is ejected from the Source Code. Everything returns to normal back on Ooo, and Ice King becomes trapped in a reappearing house wall. Princess Bubblegum then destroys Ice King's computer.
