The episode begins at the Krusty Krab when SpongeBob is taking out the trash. Then Plankton is seen trying to, once again, steal the formula. This time Mr. Krabs lets him have it, then the patty explodes as part of new Krusty Krab security measures that can backfire on customers who swallow patties whole. SpongeBob is upset that Mr. Krabs and Plankton can't cooperate with each other, and Mr. Krabs claims they're like enemies. The episode comes to a test when a new eatery called the Flabby Patty is created.
Things take an unexpected turn for the when it turns out the Flabby Patty is better than the Krabby Patty. Mr. Krabs and Plankton compete to see who could get the secret recipe, but SpongeBob explains it's best if they cooperate. They disguise themselves as an employee applying for a job. The employer hires them, and their first assignment is to memorize the secret recipe.
They are excited until the recipe is revealed to be about friendship. SpongeBob is revealed to be the employer, and he said he created the restaurant to teach them about cooperation. Mr. Krabs and Plankton are angry, and the episode ends when they chase SpongeBob with their newly-formed "Co-operation".

This is the second episode where Plankton and Mr. Krabs unite due to a new restaurant having so many customers. The first was Best Frenemies. This happens again in Eek! An Urchin.
SpongeBob references Friend or Foe when he says that Mr. Krabs and Plankton were once Best 'Palsie-Walsies'.
