NEGLECTED BY HIS PARENTS AND INSTEAD OF BEING ANGRY HE IS UNUSALLY HAPPY.

HANGS OUT WITH PATRICK TOO MUCH AND HAS A SLOW AND IMMATURE PERSONALITY

COMES FROM A FAMILY OF SEA SPONGES AND THEREFORE IS NOT REALLY BRIGHT

SPONGEBOB BELIEVES THAT FRIENDSHIP IS A VERY IMPORTANT VALUE SO HE WANTS TO BE FRIENDS WITH EVERYONE

CHASES JELLYFISHES BECAUSE IT REALLY EXCITES HIM AND MAKES HIM FEEL FREE BUT LET'S THEM GO B/C HE'S NICE
