SpongeBob SquarePants is an American animated television series and media franchise. It is currently Nickelodeon's, and is among Nicktoons Network's most-watched shows. In 2007, TIME magazine named it one of the greatest television shows of all time. Although its original network is Nickelodeon, SpongeBob is now broadcast around the world. It was created by artist, animator and former marine biologist Stephen Hillenburg, and is produced through his production company, United Plankton Pictures, Inc. It is the second longest-running Nicktoon, next to the Rugrats.

The series is set in the Pacific Ocean, in the fictional city of Bikini Bottom and on the surrounding lagoon floor. The pilot episode first aired in the United States on Nickelodeon after the Nickelodeon Kids' Choice Awards on May 1, 1999. The "official" series premiere followed on July 17, 1999, with the second episode, "Bubblestand/Ripped Pants."

The series star is a character who is a sea sponge, but in shape and color his body more closely resembles a kitchen sponge.

Plot

SpongeBob SquarePants is a sea sponge who lives in a pineapple under the sea, while his squid neighbor, Squidward Tentacles, lives in a moai. SpongeBob's other neighbor and best friend is a pink and highly idiotic starfish named Patrick Star, who lives under a rock. SpongeBob and Patrick live on either side of Squidward Tentacles, a highly arrogant and egotistical squid who hates them (especially SpongeBob) because of their annoying habits and is quite open about it.

SpongeBob's house-pet is a snail named Gary, who meows like a cat. Although Gary only speaks in a few episodes, the characters have shown an ability to understand him. In addition to this, underwater worms bark exactly like dogs, and are kept on chains. Jellyfish are the equivalent of bees; buzzing, "stinging" with electricity, and producing delicious "jelly", mocking the name "jellyfish", while still referring to a bee's honey. Clams act as birds, and fish act as the citizens of the community but generally are not important characters.

Although the citizens of Bikini Bottom live underwater, they mostly do not float, and gravity usually applies. A flurry of bubbles accompanies actions in many of the episodes to remind the viewer that the setting is underwater. However, the laws of physics in Bikini Bottom change somewhat from time to time, but mostly the water acts like air. For instance, characters can pour a glass of liquid, just as we do above the sea. Bikini Bottom has functional baths, pools, and toilets, and there are lakes and streams. In Battle for Bikini Bottom and a regular beach setting, Goo Lagoon, underwater liquid is referred to as goo. Once, during an episode set in a wilderness area, Patrick questions how a camp fire is possible on the lagoon bottom. As soon as the question is asked, the fire is immediately extinguished with a sizzle; however, this is only used for comedic effect, as fire is often used and seen. In another episode, Squidward sets up a functional electric fence. Strangely, all creatures in the series (sans Sandy) are completely dependent on water for survival; if any sea creature on the show (even those that can survive above water, such as crabs) go on dry land, they begin to rapidly dehydrate and eventually suffocate.
