Authentic sound effects and playful music help tell the fun story of “Sammy the Steamroller.” When Bob, the engineer, tells his crew that there is an important job to do, Sammy the Steamroller races to help his friends, Connie the Crane, Dan the Drill, Bill the Bulldozer, and Charlie the Cement Mixer. But Sammy learns that his job must be last. At first, Sammy is sad until he learns that even though his job may be the last one, it’s just as important as all of the others.
