Cito always helps the little buses, but he is also sometimes strict. The little buses feel a bit uncomfortable around Cito because he always looks like he knows what he's doing.
They think Cito is an entirely different kind of being. Then one day, Buba, the grandfather bus who was Cito's predecessor, arrives. Seeing Cito become flustered in Booba's presence, the little buses are dumbfounded. Buba tells the little buses stories of Cito's childhood.
