SpongeBob SquarePants premiered on Nickelodeon in 1999, with a theme song built around the call-and-response question of who lives in a pineapple under the sea. The Spanish-language version keeps the same playful structure, which helped it travel with dubbed episodes across Spanish-speaking audiences. Online, the short opening line is now lifted as a standalone clip for edits, reaction videos and memes, because almost anyone can finish the line and recognise the show instantly, even without hearing the full theme.
