Now that Mordecai and Rigby had broken Skips' pact, the Guardians kidnap Skips and are about to kill him. As it turns out, Skips had made a pact with the " Guardians of Eternal Youth", who were giving Skips the gift of immortality as long as he performed the spirit dance every birthday. Mordecai and Rigby try to bring Skips to the party, but they interrupt him while he's doing a spiritual dance. But on the night of his birthday, Skips secludes himself in a forest instead of going to his party. Mordecai and Rigby try to seize an opportunity to eat a piece of cake, and it comes when they learn that Skips’ birthday is coming soon. Later, when Mordecai learns of Rigby's plan, he also decides to steal some Death Kwon Do moves in order to stop him. He steals the instructions for the "Death Punch" and learns it, so Rigby decides to try out the move on unsuspecting people as he prepares for his revenge against Mordecai. Tired of Mordecai always beating him at punchies and getting his way, Rigby decides to learn the martial art of " Death Kwon Do". Mordecai and Rigby race against them as they try to get the tickets back, and also to arrive at the concert on time. Mordecai and Rigby buy tickets for themselves but when they fail to buy tickets for the coffee bean and the translator, the two steal Mordecai and Rigby's tickets. When they run out of coffee, they agree to get some more with the help of a giant coffee bean and his translator (also interested in the concert), in exchange for tickets for them as well. While working, they drink lots of coffee to keep them active.

Mordecai and Rigby work overtime in order to get tickets to a Fist Pump concert. In the process, they accidentally unleash an 8-bit demon from an old arcade game of the same name called the Destroyer of Worlds who tries to destroy the world. While preparing for a birthday party, Mordecai and Rigby are assigned to set up chairs, and the two try to get the job done to prove to Benson they are not slackers. They must now rescue Skips, while fleeing from a monster at the same time. They then decide to instead use the magic keyboard to give them everything they want, though they accidentally send Skips to the moon with it along with other random items. When Mordecai and Rigby accidentally make a hole in the wall while wrestling a stuffed animal, they use the keyboard to make Pops and Benson give them raises to try to pay for it. Rigby steals a magic keyboard from a preoccupied sorcerer. Mordecai and Rigby play rock-paper-scissors over a chair and tie 100 times, but it ends up summoning the Black Hole Monster.
