Paul Harrison Tibbitt (born May 13, 1968) is an American animator, television producer, writer, storyboard artist, songwriter, voice actor, and director, best known for working on the animated series SpongeBob SquarePants. After SpongeBob creator Stephen Hillenburg resigned in 2004, Tibbitt took the position of showrunner for the show. He also took over as the voice of Potty the Parrot, whom Hillenburg had voiced until his resignation. Tibbitt made his feature film directorial debut directing The SpongeBob Movie: Sponge Out of Water. He studied in the Character Animation program at the California Institute of the Arts. In 2015, Vincent Waller (a creative director) and Marc Ceccarelli (a writer and storyboard director) took Tibbitt's place as supervising producer and showrunner. It was also announced that Tibbitt would leave the series after season 9 to work on The SpongeBob Movie: Sponge on the Run (which is being produced without the involvement of the show's crew by a separate crew), but he lended his directing and writing position to Tim Hill. He now works at DreamWorks Pictures.
