SpongeBob is a fun-loving, hyperactive, clueless, abnormal and immature sponge with a happy-go-lucky personality. Despite being portrayed this way, he is somewhat smart and knows about what is right, an example being telling Patrick angrily not to draw his picture of calling Mrs. Puff a "big, fat, meanie" because she's a teacher. He is extremely determined and will often stop at nothing to accomplish a task. He is also somewhat dramatic to the people who are kind to him: for example, to the mail-fish.
