What Makes Bobby Run?

Bobby is chosen to be the mascot for Tom Landry Middle School.  When he informs Hank and friends of the news, they tell him about a tradition where the rival school's band beats up Arlen's mascot when Arlen is ahead.  When Arlen takes the lead in the game, Bobby runs away, disgracing the whole school.  He enlists Dale's help in trying to regain his reputation by kidnapping the mascot of another school.
