Billy

Billy is a fourth grader at Lakewood Elementary School. He got his name in "Arthur and the Real Mr. Ratburn". He was previously in Mr. Ratburn's third grade class. He is also a member of the Tough Customers a group of bullies at Lakewood and has had very few speaking roles. Despite the fact he is a member of the Tough Customers there is a chance he might be friends with Buster as was seen in the episode Buster Makes the Grade, which adds the possiblity that some or all the members of the Tough Customers hang out with the main characters.
