S02:E05 - Vertie's Stunt School / Dancing Wheels

Chuck's Uncle Vertie teaches Chuck and his friends a new trick on the half-pipe, but if Chuck wants to perform it in the upcoming stunt show, he must practice, practice, practice! /A girl truck named Chassie tries to get Chuck and his buddies to help with a dance routine, but Chuck thinks dancing's not for them. At least, not until Chassie's dance moves solve a racing problem for Chuck!
