SpongeBob SquarePants (born July 14, 1986) is the eponymous character and protagonist of The Life of SpongeBob SquarePants. He currently works as a cook in the Krusty Krab, a job that he has held since 1999. SpongeBob loves his job most of the time and usually shows little indication that he will leave it.
SpongeBob is generally a good-natured person; he is cheerful, fun-loving, and optimistic, albeit also childish from time to time. He has two neighbors: Patrick Star and Squidward Tentacles. Patrick is SpongeBob's best friend, and they love to fool around when they have nothing to do at all. Squidward mostly despises SpongeBob and Patrick for what he sees as their childish, irresponsible behavior, and does not relish the idea of working with SpongeBob at the Krusty Krab. Nevertheless, Squidward is also ready to warn and protect SpongeBob if he thinks that SpongeBob has gone too far, as shown in the season 1 episode "Our Temporary Manager, Mr. SquarePants!", in which Squidward, out of a mixture of anger, panic, and concern, warns SpongeBob that his hands-off, often ignorant approach to management is endangering the Krusty Krab.
SpongeBob loves working at the Krusty Krab (much more than Squidward). He maintains a good relationship with his boss Mr. Krabs, and Mr. Krabs trusts SpongeBob enough to let him run the Krusty Krab in his absence (as shown in "Our Temporary Manager, Mr. SquarePants!"), although this is quickly shown to be a grave, near-fatal mistake.
While SpongeBob can be very childish, he is also shown as mature and farsighted under certain circumstances; an example being his voluntary resignation as Temporary Manager to avoid the collapse of the Krusty Krab, immediately following his kind dismissal of Patrick as temporary cook. Careful not to hurt his best friend's feelings, SpongeBob states his decision in a calm, respectful manner and encourages Patrick not to give up on anything in life.
As shown by Mr. Krabs' formal, written statement handing over the management of the Krusty Krab in "Our Temporary Manager, Mr. SquarePants!", SpongeBob SquarePants was born on July 14, 1986.
SpongeBob works at the Krusty Krab, the most popular restaurant in Bikini Bottom; he has worked there since 1999. Explaining (to Squidward) his entrance into the restaurant at the age of 13, SpongeBob states that the Bikini Bottom government notes that he is extremely self-sufficient for his age; he already lives in his own house, manages his finances competently enough to avoid falling into poverty, and, while he can be very childish at times, he can control his emotions and rarely shows his anger, something that is usually unexpected for that age. As a result, the government gives him "special permission" to live and work independently, which he has done successfully so far.
