SpongeBob SquarePants premiered on Nickelodeon in 1999, created by Stephen Hillenburg, and its opening theme has played at the start of episodes ever since. The song introduces SpongeBob and his home in Bikini Bottom through a call-and-response pirate shanty, a format that made it easy to parody and remix. As clips circulated on YouTube, TikTok and meme pages, the theme became shorthand for childhood nostalgia and cheerful absurdity. It remains popular because almost everyone recognises it instantly, even without seeing the show.
