Sheriff Callie gets Sparky a "lucky scarf" in hopes that it will improve his racing skills before a big race after he loses his confidence after slipping during a trial run. Peck is trying to eat one of Priscilla's "Belly Sinker Biscuits," Peck pecks at it and bends his beak. Sheriff Callie calls the dentist, Dr. Wolf, but nobody knows Dr. Wolf is the dentist. He looks scary (After a rough stagecoach ride that messed up his hair) and when he says that he's going to "straighten out the Deputy," everyone – even Peck himself – is terrified of him. So Toby tries to disguise himself as Peck to lure Dr. Wolf away while Peck looks for Sheriff Callie ending in a disastrous collision between the two. But Peck,Toby and the townsfolk learned to never judge a person in their appearance no mater how they look like.
