SpongeBob SquarePants began on Nickelodeon in 1999, and the squeak of SpongeBob's black shoes became one of the show's running sound gags, heard whenever he walks, marches or dances across Bikini Bottom. Editors later lifted single steps as isolated meme sounds, splitting longer walks into short parts like this second clip. Its appeal online is its instant recognition: one squeak signals a whole cartoon walk without needing dialogue, music or footage, which is why it survives in short edits, soundboards and reaction videos.
