Gordie loves his third grade teacher, but sharing a locker with a girl instead of his best friend, plus trouble with a school bully, may ruin his best year ever.

Disappointed when his friend Lamont's mother makes him a silly Halloween costume, especially since Lamont always has the best costumes, Gordie is determined to find another costume—one that will be the most frightening and terrifying costume ever.

Third-grader Gordie is not only having problems with his best friend, he also has to teach his not-so-smart dog some tricks for the upcoming school talent show.
