He looked more like Yoda than an Ewok to be honest. He had crusty green hands and long finger nails. Fatz is Justin's nickname. Fatz pretty much became one of our cartoon characters and was rarely used as a reference to Justin. He has a meatball for a nose.
Food is a fat guy with long red hair.
Everyday he will wear a football jersey. His name came about when Josh was over Justin and Ryan's. They were talking about something else and said the word food in their conversation. That was the only word Josh heard and assumed it was the guy's name. So it stuck with him.
