what killed squidward

It is important to note that Squidward did not actually die in any episode of SpongeBob. However, there is a fan-made horror story known as "Squidwards Suicide" that has spread across the internet. The story is about the anthropomorphic octopus character supposedly killing himself with a shotgun. The details of the story vary depending on the source, but it is not a real episode of SpongeBob SquarePants.
