At the catering company Mung is unveiling his latest culinary creation, the firesnacker, to the rest of the gang. The dish ends up setting the kitchen on fire, prompting Schnitzel to complain. Mung refuses to have his techniques questioned as he is the master of this kitchen and shows off his Certifrycate to prove it. However, mid boast, his certifrycate is taken by a man from the ECEA, or Expired Certifrycate Enforcement Agency, who informs him that his certifrycate has expired and to renew it, he and Chowder must to go to Reuben's School of Certifrycation. On arriving at the school, they run into Ms. Endive and Panini who must renew as well. The teacher, Reuben, appears and explains how the class works. He likens the class to a cruise on the good ship YumYum. The ship sails smoothly as long as it follows the recipe and all those that don't follow the recipe become Recipe Pirates, never get their certifrycate, and the only place they will be allowed to cook is in a dumpster. So Mung and Chowder get to work.
The first task is to boil water. Endive measures the flames and selects the right pot and pours the water, boiling it to perfection. Mung and Chowder attach a motorcycle to a huge cauldron in what Mung calls "toiling" water, as any two-bit chef can simply boil it. Mung is awarded a Recipe Pirate hat.
The next task is to prepare a sandwich. Reuben finds Endive's sandwich fantastic. However, Mung, who has followed the recipe to the letter despite his disagreements with it, is failed since he included mayonnaise, which Reuben is allergic too. So, even though he followed the recipe, Mung is given an eye patch.
Over the next series of tests, though Mung does his best to please Reuben, he fails time after time until he is completely decked out in Recipe Pirate attire and Chowder is dressed like a parrot.
For the final exercise they have to simply cut a piece of cake. Mung is torn on whether to listen to his instincts or go by the book as Reuben wants. His hesitation and confusion leads Reuben to have them walk the plank into the dumpster. While Mung is lamenting about why Reuben doesn't like his cooking, Chowder cheers him up with a song that says how great he is. Mung reclaims his pride and decides to go back and give Reuben a piece of his mind. Meanwhile, Reuben is preparing Endive's certifrycate, even putting his phone number on it. Mung swoops in ,like the Recipe Pirate Reuben made him out to be, and steals the certifrycate. Reuben tells Endive that she might be staying a little bit longer to get a new one. Mung presents his new certifrycate, with Endive's name crossed out and his own written in, to the gang. Truffles tells him that he's done it again, in that he's somehow set the kitchen on fire... again. But Mung just tells her, "That's what I do, baby. That's what I do."
