SpongeBob SquarePants (character) - Development

Development

Stephen Hillenburg had made several "horrible impersonations" before he finally conceived his character. He intended to create a series about an over-optimistic sponge that annoys other characters. Hillenburg compared the concept to Laurel and Hardy and Pee-wee Herman. As he drew the character, he decided that a "squeaky-clean square" (like a kitchen sponge) fits the concept.

The first concept sketch portrayed the character as wearing a red hat with a green base and a white business shirt with a tie. SpongeBob's look gradually progressed to brown pants that was used in the final design. SpongeBob was designed to be a kid-like character who was goofy and optimistic in a style similar to that made famous by Jerry Lewis.

Originally the character was to be named SpongeBoy but this name was already in use. This was discovered after voice acting for the original seven minute pilot was recorded in 1997. The Nickelodeon legal department discovered that the name was already in use for a mop product. Upon finding this out, Hillenburg decided that the character's given name still had to contain "Sponge" so viewers would not mistake the character for a "Cheese Man." Hillenburg decided to use the name "SpongeBob." He chose "SquarePants" as a family name as it referred to the character's square shape and it had a "nice ring to it".

Although SpongeBob's driver's license says his birthdate is July 14, 1986, which would make the character 13 years old at the time of the series' "official" premiere on July 17, 1999, Hillenburg joked that he is fifty in "sponge years". He explained that SpongeBob actually has no specific age, but that he is old enough to be on his own and still be going to boating school. The decision to have SpongeBob attend a boat driving school was made due to a request from Nickelodeon that the character attend a school.

SpongeBob is voiced by veteran voice actor Tom Kenny. Kenny previously worked with Hillenburg on Rocko's Modern Life, and when Hillenburg created SpongeBob SquarePants, he approached Kenny to voice the character. Hillenburg utilised Kenny's and other people's personalities to help create the personality of SpongeBob.

The voice of SpongeBob was originally used by Kenny for a very minor female alligator character named Al in Rocko's Modern Life. Kenny forgot the voice initially as he created it only for that single use. Hillenburg, however, remembered it when he was coming up with SpongeBob and used a video clip of the episode to remind Kenny of the voice. Kenny says that SpongeBob's high pitched laugh was specifically aimed at being unique, stating that they wanted an annoying laugh in the tradition of Popeye and Woody Woodpecker.

When SpongeBob SquarePants is broadcast in non-English languages, the voice actors dubbing SpongeBob's voice use Tom Kenny's rendition of the character as a starting point but also add unique elements. For example, in the French version of the series, SpongeBob speaks with a slight Daffy Duck-style lisp.
