Bob the Sponge is a very early version of SpongeBob SquarePants.
Stephen Hillenburg first made Bob the Sponge in 1989, for a comic book; The Intertidal Zone, Bob the Sponge co-stared with Rocky the Shrimp in the comic book as well. Bob the Sponge actually resembles a real sponge, but he wore sunglasses and had a mouth to speak with. Bob the Sponge had evolved into SpongeBoy around 1994, and later evolved into SpongeBob SquarePants. Bob the Sponge and SpongeBoy are both proto-types of SpongeBob, though SpongeBoy resembles SpongeBob more than what Bob the Sponge does.
- SpongeBob's French name Bob l'eponge can be translated to Bob the Sponge.
