National Free Balloon Day is an event that the Bikini Bottomites celebrate. This event is about fun, and people get free balloons when they visit Seashell Park. It is only celebrated in the episode "Life of Crime."
National Free Balloon Day was celebrated all day during the time of "Life of Crime." SpongeBob and Patrick decided to "borrow" a balloon and ended up popping it. However, SpongeBob and Patrick then assumed that they stole the balloon and they both went to the police station. However, they were let out as soon as they came in with the policemen, particularly Officer Rob Johnson and Officer John Slugfish, telling them that SpongeBob and Patrick took a balloon on Free Balloon Day.
- SpongeBob and Patrick thought they stole a balloon on Free Balloon Day. For whatever reason, they did not know that day was National Free Balloon Day, despite the fact that they were explicitly told that it was.
- On his official Twitter in 2017, SpongeBob confirmed that National Free Balloon Day is on December 27.
