I'll tell things about him.
He annoys people a lot and he is clueless about everything he's doing.
He lives in the Bikini Bottom with his neighbors, Patrick Star and Squidward Tentacles, and with the rest of his friends.
His best friend is Patrick Star, which is a stupid starfish. They are a perfect duo because they both cause trouble and disturbance to the residents of Bikini Bottom, but mostly to Squidward. Squidward is a squid but for me, he is an octopus. That's all I have to say for now. The rest, you'll have to find out for yourself. Watch it on Nickelodeon.
Spongebob is not much of a character that gives us moral values but in everyday of our lives, we need to just go away from our stress and be relaxed for a while. I think that's the message of Spongebob to everyone.
