Sponge-O is a cleaning product that is sold at the Barg'N Mart. It only appears in the episode "Karate Star," where Patrick mistook it for SpongeBob SquarePants, but the store owner Dennis told him that it wasn't SpongeBob and it was only a cleaning sponge.


Sponge-O is a simple cleaning sponge that is yellow and looks a lot like SpongeBob, but is much smaller. It is wrapped up in a small plastic bag with the words "Sponge-O" printed at the top, in purple writing.
