Roley is a motor-roller who works for The Crotoonian Construction Co.
A laid-back motor-roller with a tendency to sing on the job, Roley makes sure the work's done flat while keeping cheerful and excited with his own songs.
Roley bears a very close resemblance to a Zettelmeyer diesel road roller.
Roley is green with black rollers and an orange siren.
