These aren't the kind of installments that will legitimately frighten most viewers, but they do work as the perfect episodes for fans to watch to get in the mood for the Halloween season. While the series is known for being hilarious and often outlandish, it actually has delivered more than a few spooky episodes over its time.
SpongeBob Squarepants' great episodes made it one of the most popular and beloved animated shows of all time, maintaining an impressive run since way back in 1999. These can be unintentionally terrifying for a few children, while others also include intentional parodies of horror films. For a kid's show, a few episodes can also get dark or disturbing. However, underneath the simple wit, the show can get meta at times, with genius references, and even subtle adult jokes occasionally. Set in the underwater town of Bikini Bottom, it revolves around fry-cook SpongeBob and his misadventures with his friends. Nickelodeon's most popular cartoon, SpongeBob Squarepants, is filled with episodes that evoke an illogical, goofy sense of humor, not to mention some really disturbing scary SpongeBob episodes.
