Little Excavator and Big Helpers

Once, little excavator Max met a paper airplane. They wanted to play, but the wind carried away the new friend. Max chased after it and accidentally broke some traffic rules. Thus begins a great adventure in which Max meets a police car, a boom lift, a garbage truck, a fire truck, a street sweeper, a watering truck, and an ambulance. He helps everyone he encounters along the way, and in the end, he realizes: it doesn't matter whether you're big or small.
