List of prototypes

SpongeBoy was the original name for SpongeBob SquarePants. The name was created by Stephen Hillenburg but was changed to SpongeBob after it was discovered that the name was copyrighted.


His looks were practically the same as SpongeBob and he most likely had the same voice (except he wore a green hat). He also had longer and pointier shoes along with the hat. He seemed to have a goofier facial expression, rather than the SpongeBob now.


  • In the episode "Squeaky Boots," Mr. Krabs calls SpongeBob "SpongeBoy, me bob!," a possible reference to his original name.
  • In "It's a SpongeBob Christmas!," Plankton references the name when he says "Now I just need to figure out what to do about ol' SpongeBoy."
  • The reason the name wasn't put to use was because the name was already taken by a mop company.
  • SpongeBoy has 13 holes always visible on his head. SpongeBob has 7.
