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 as they don't have any music to entice them to march as a marching band. To get the mice to move, Putt-Putt must turn on his radio, so the mice will march off as a marching band. On the residential street, Putt-Putt can mow the residents' lawns and bring them groceries.
Only one resident, Gert, joins the parade.
