Peanut, the new member at the garage, enthusiastically prepares for his first day of work and everyone expects a great job from him based on his outstanding driving skills when he practiced. However, Peanut finds it difficult to work as a city bus because of his personality and attitude.
He loves to hear from everyone and give compliments to each and every passengers which led to leaving stops late. Even one time he left the route because he wanted to passengers to listen Jenny's song.
As he continues working hard, he grows envious of Citu the tour bus. Peanut has the opportunity to temporarily fill in as a tour bus and go with Citu and Tayo to the mountain! Will he eventually becomes the tour bus? or town bus like Tayo, Rogi, Lani and Gani?
