Skye Sampson is hosting a beach motocross race and appoints Bob and the team to build the course. Not only is Bob creating the course, he plans to race on it, too. The Machines, aware of the excitement surrounding the race, are determined to hold a race of their own. Using the finished course, they hold an unofficial race that ultimately destroys the site. The team pulls together, works through the night, and the course is ready the next morning. Bob competes in the race and finishes second place to a mysterious masked biker—Wendy!
