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.

Answer: May 1, 1999
