Watch SpongeBob SquarePants series free. SpongeBob SquarePants is one of the highest-rated children's cartoon shows of the era, and of all time. It follows a naive and eternally optimistic sea-sponge (that is funnily enough shaped like a kitchen sponge) named SpongeBob SquarePants, and his endeavors in the underwater town of Bikini Bottom. Many supporting and equally popular characters tag along with SpongeBob, including a starfish, squid, crab, and squirrel that lives underwater.
