In a big city where various vehicles are happily living together, our little bus Tayo has just started learning his route in the city. There is lots more to learn for Tayo. Tayo and his friendly friends Rogi, Lani and Gani are helping each other to become great mature buses.
Rogi brags about the rubbish he's collected to the little buses, who get angry at him because the rubbish is so dirty. The next day on his route, Rogi meets a camping car named Windy who has the same taste as he does.
