Role in series
"Life of Crime"
Chocolate bars make a small appearance in this episode but play a major role for the climax. After Patrick thinks they are going to starve, SpongeBob takes out two chocolate bars for them to eat. Patrick ends up eating his chocolate bar but then does not know what happened to it. He then accuses SpongeBob of taking his chocolate bar and wants him to give it back.
SpongeBob denies trying to tell Patrick that he already ate it but Patrick does not budge. SpongeBob even offers to share his chocolate bar but Patrick still thinks he stole his and wants him to admit he took it.
SpongeBob gets fed up with Patrick's accusations and finally decides to eat his chocolate bar. He eats it very slowly as a means to mentally torture Patrick.
For the entire episode, SpongeBob and Patrick decide to sell chocolate bars in order to start living the fancy life. In the beginning, they do not do so well, as they are constantly being chased by a crazed Tom yelling "Chocolate!" and being conned by a fish, though SpongeBob and Patrick did not know that they were being conned the entire time. SpongeBob finally gets an idea to sell chocolate by "stretching the truth."
This works out to much success, as they manage to sell many bars of chocolate to most of the people of Bikini Bottom. However, they end up being conned by the con man after he fakes being in a full body cast.
When SpongeBob and Patrick look like they are going to give up, Tom appears again and scares them. However, he ends up buying all of SpongeBob and Patrick's chocolate with a huge stack of money and the duo can finally start living the fancy life. They end up buying a fancy restaurant and go on a date with two mucholder fish.
When Squidward commands SpongeBob to do a task so simple that even someone without a brain can do it, the latter informs the former that he gave his brain to Patrick in exchange of two chocolate bars. He is later seen eating them when he is stuck inside Squidward's vacuum cleaner and his brain has been given back to him in the process.
