He looks similar to SpongeBob except he has a black mustache and goatee and wears round black glasses, orange-and-blue-striped pants, a red tie with olive green dots, and purple and white shoes.
He is very messy; his socks are so smelly that Squidward tries to complain about it, but SpongeBob does not let him. When SpongeBob and Patrick come back from Patrick's house, there are smelly socks and pizzas everywhere.
Todd SquarePants was born to an unknown Mr. and Mrs. SquarePants.
When he was an adult, he stayed with SpongeBob for a few days.
