Cowbob and the Teeter-Totter Gang by Chandre Bronkhorst

When his Pa accepts a job in New York City, Robert is ripped from the only world he has ever known. With his farmhouse vanishing in the distance of the rear-view mirror, he is forced to cope with life’s problems in the usual way. He closes his eyes and opens his mind, escaping to a world where he has control. No longer Robert from Arkansas, he takes on the infamous Teeter-Totter Gang as Cowbob.
The more Robert struggles to adjust to the new life he was thrust into, the more problems seem to be thrown his way. When Bullies try to take him down, he looks to Cowbob to show him the way.
