It's currently unknown what will happen with SpongeBob SquarePants, his creation. I really have no clue.
Stephen Hillenburg, although born in Lawton, Oklahoma, he grew up in Anaheim, California. His experience with marine things led to his best-known creation, SpongeBob SquarePants. The SpongeBob SquarePants show we love was pitched to Nickelodeon in 1997, but premiered two years later on May 1. Hillenburg left the show after the first SpongeBob SquarePants movie, but briefly returned for the second one.
Requiescat in pace, Stephen Hillenburg!
