Blue Street is one of the three residential streets found north of Cartown in Putt-Putt Joins the Parade. On the road to the houses, four small mice in marching band uniforms are sulking in the middle of the road. To get the mice to move, Putt-Putt turns on his radio and the four of them march off. On the residential street, Putt-Putt can mow the residents' lawns and bring them groceries.
Only one resident, Gert, joins the parade.
