and how mesmerized children were by tide-pool animals, including crabs, octopuses, starfish, and sponges. It came to him that the series should take place underwater, with a focus on those creatures: "I wanted to create a small town underwater where the characters were more like us than like fish. They have fire. They take walks. They drive. They have pets and holidays." It suited what Hillenburg liked for a show, "something that was fantastic but believable." He also wanted his series to stand out from most popular cartoons of the time exemplified by buddy comedies such as The Ren & Stimpy Show (19911995). As a result, he decided to focus on one main character: the weirdest sea creature that he could think of. This led him to the sponge: "I wanted to do a show about a character that was an innocent, and so I focused on a sea sponge because it's a funny animal, a strange one." In 1994, Hillenburg began to further develop some characters from The Intertidal Zone, including Bob the Sponge. Bob the Sponge is the comic's "announcer". He resembles an actual sea sponge, and at first Hillenburg continued this design because it "was the correct thing to do biologically as a marine-science teacher." In determining the new character's personality, he drew inspiration from innocent, childlike figures that he enjoyed, such as Charlie Chaplin, Laurel and Hardy, Jerry Lewis, Pee-wee Herman, Abbott and Costello, and The Three Stooges. He then considered modeling the character after a kitchen sponge, and realized that this idea would match the character's square personality perfectly: "[I]t looked so funny. I think as far as cartoon language goes he was easier to recognize. He seemed to fit the character type I was looking fora somewhat nerdy, squeaky clean oddball." To voice the central character of the series, Hillenburg turned to Tom Kenny, whose career in animation had begun with his on Rocko's Modern Life. Elements of Kenny's own personality were employed in further developing the character. While pitching the cartoon to executives at Nickelodeon, Hillenburg donned a Hawaiian shirt, brought along an "underwater terrarium with models of the characters", and played Hawaiian music to set the theme. Nickelodeon executive Eric Coleman described the setup as "pretty amazing". Although Derek Drymon, creative director of SpongeBob SquarePants, described the pitch as stressful, he said it went "very well". Nickelodeon approved and gave Hillenburg money
