In what year did this pilot episode air of this American animated television series, whose title character held the same name as the show and also included the character Mrs. Puff?
Mrs. Puff Mrs. Puff is a fictional character in the American animated television series "SpongeBob SquarePants" and both films based on the franchise. She is voiced by actress Mary Jo Catlett and debuted in the season one episode "Boating School" on August 7, 1999. Mrs. Puff was created and designed by marine biologist and animator Stephen Hillenburg. He developed the character in response to a request from Nickelodeon that the show star a schoolteacher. Hillenburg did not want to write SpongeBob as a school-age child, so Mrs. Puff was introduced as his driving instructor rather than a classroom educator.
