153b - The Other Patty

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 them 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."
