It's a new school year for Billy and his bulldozer friends. Nothing is more important to them than winning the Rocky Rumble, a hauling competition that decides who will be the class leaders. Billy has been moving rocks all summer long; he's ready to win! But his hopes are dashed when he's assigned to work with Crawley, a friendly bulldozer who's as slow as a cement truck. As the competition draws near, Billy must decide if he will keep Crawley as a partner or leave him behind to become the champion. As The Rocky Rumble explores themes of friendship, kindness, and empathy, it provides an enjoyable way for children to practice putting themselves in someone else's shoes.
