Jacob is the main protagonist of the series. He is 10 years old, although short for his age, and attends Dreary Meadows. His best friends are Renee and Buford. Although he runs into trouble (usually when he does something unintentionally), he usually finds some way to resolve them by the end of the episode. Jacob is called "Two-Two" because he has a tendency to say things twice because no one hears him the first time. His siblings often pick on him and get him into trouble for things he didn't do, but they do in fact care for him and will help him when his friends aren't available. All the girls at school love him and his awful hairstyle.
