jalopy:

Stephen Hillenburg (creator of Spongebob Squarepants) character designs for the cast of Spongebob from his pitch bible.

Fun Facts:

Spongebob was originally named Spongeboy but the name was forced to change after they discovered it was already being used.

Barnacle Boy was originally Barnacle Bill, who looks horrifying. I assume the design changes of the two underwater superheroes was due to the voice actors they hired for them (Ernest Borgnine and Tim Conway.)

Now this is cartoons!
