Baby SpongeBob is an alternate universe version of SpongeBob SquarePants, who comes from a universe where SpongeBob and Patrick were likely born several years after their main universe counterparts.


He looks like SpongeBob but is smaller, younger, and has a pacifier in his mouth. He is also shown wearing a diaper.


He appears slapping his head after SpongeBob realizes that Super SpongeBob SquarePants is the hero of the Bikini Bottom 2 universe.
