The episode starts out when two customers park at the Chum Bucket. Plankton thinks they want to eat there, but they couldn't find parking at the Krusty Krab. Karen then suggests that Plankton should advertise his product. Plankton then hangs a sign that says CHUM IS METABOLIC FUEL! Patrick comes along and tries to read the sign, but his head starts smoking from the strain of trying to understand what the words are. After his head is put out,
Patrick then rearranges the letters so the sign reads CHUM IS FUM! The new slogan starts to attract customers. Plankton hires Patrick as his slogan manager. Meanwhile back at the Krusty Krab, Mr. Krabs believes Plankton has stolen the secret formula, and comes up with a plan to steal the formula back. Plankton sees through their disguise and they realize that it was the slogan that brought in the customers, despite the fact the chum tastes awful. (To combat the disgusting taste of the chum, the coustomers simply say Chum Is Fum over and over.) Then Plankton goes to Patrick to check on how his new assignment to come up with new slogan ideas is going. However, all Patrick does is write Chum is Fum in a thousand different ways. Plankton then gets mad at Patrick, but cools down because Patrick's slogan is still attracting coustomers. A few days later, people are getting bored of the slogan, so Plankton and Patrick hold a board meeting. Patrick comes up with a new slogan three days later, changing it to FUM IS CHUM. This brings back Plankton's customers, much to the chagrin of Mr. Krabs. Business is so large Plankton gets into the restaurant magazines and even a hockey team shows up to eat. Patrick then decides the resign from his postion as advertising director because he is "burnt out." (There is literally a hole burned into the back of his head.) Plankton protests, but then bluffs to make Patrick believe that he is desposible, and not nessacrerry to keep customers eating at the Chum Bucket. During his rant, Plankton accidentally insults his customers over the intercom that he had installed by the cash register earlier to taunt Mr. Krabs. His customers hear him calling them "bufoons, morons, the dumbest of the dumb" among other things, which causes all his customers to abandon their chum in anger. Plankton then gets beaten up by the hockey team. At the end, everyone sees Patrick finishing a sign that says the Krusty Krab's new slogan, KRABBY PATTIES ARE FUM! and everyone returns to the Krusty Krab.
