Doug's old best friend Bobby Bodingo is moving to Bluffington, and Doug can't wait to show him around school and introduce him to his friends. But Bobby just isn't the same as he used to be: he's rude and crude and even makes Doug go in the girl's bathroom. As a result, all of Doug's friends don't like him and won't spend time with Doug if Bobby is around him. Furious after not being joined by Patti, Beebe, and Skeeter, Doug angrily tells Bobby to stay away from him. Realizing Bobby needs his support, Doug goes to make it up to him.
