Occasionally, SpongeBob is too ignorant to notice impending danger and his unworldly thinking may put himself or others in peril. He also hates hot sauce (see "Karate Choppers"). He is afraid of the dark (or what is in the dark) (see "Night Light") and clowns (see "Rodeo Daze"). SpongeBob can become scared easily and usually panics when frightened. Despite his well-meaning intentions, SpongeBob's actions often annoy and cause trouble for those around him, most notably his next-door neighbor, Squidward Tentacles. His selfless nature is most notably shown in "Best Day Ever," where he sacrifices his "perfect day" to help his friends. He is a very selfless and loyal person, especially towards those close to him. SpongeBob is very kind-hearted and innocent, and very rarely acts openly mean to anyone, even his enemies.
He sometimes tends to make mountains out of molehills, such as losing his nametag (see "Missing Identity."). Sometimes, though, he shows his devious side when trying to get Mr. He is also somewhat dramatic to the people who are kind to him, for example, to the mailfish (see "Karate Island"). He is an extremely determined person, and will often stop at nothing to accomplish a task. SpongeBob is a clueless, abnormal, immature, fun loving and hyperactive character with a happy-go-lucky personality. SpongeBob sometimes sleeps in his underwear, and at other times pajamas (beginning in Season 5). While working at the Krusty Krab, he wears a tall, white hat with a small blue anchor on it as a uniform. He typically wears a white shirt with a red tie, black leather shoes with shoelaces, and brown rectangular pants with a black belt (the entire outfit is sometimes referred to as his "pants," hence his name). In the comic strip Eye Drop, his left eye is called Eyebally. SpongeBob has large blue eyes, a long, slightly curved nose, a large mouth with two prominent front buck teeth, and dimples with three freckles on each cheek. However, in episodes that are more recent, he is more of a regular square shape.
In earlier episodes, he is wider near the top and gets skinnier going further down. SpongeBob SquarePants is a cute sea sponge, but he is drawn to resemble a kitchen sponge, being rectangular and bright yellow with a dirty golden outline.
