It's time for hoedowns and campfire fun when Bob (funnyman Greg Proops) and his gang of building machines head West for their biggest construction project ever in this musical special of the popular animated kids' show. Hot on the trail of lost treasure and hidden gold mines, Bob gets help from a cowgirl named Rio (Suzi Quatro); her horse, Dollar; and her talking pickup truck, Jackaroo (Donny Osmond).
