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, and blue shoes.
He is very messy, he takes off his socks and socks are so smelly that Squidward tries to complain 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.
"Can I come in?"
"You don't mind if I stay for a few days, do you?"
