Curly was a member of the Steamrollers, a gang of juvenile delinquents, when he met the Death Defying 'Devil and his Little Wise Guys. After the clash between Steamrollers and Little Wise Guys caused Meatball to die of pneumonia, the remorseful Curly turned against the gang and joined Scarecrow, Jock and Peewee in the group. They aided 'Devil in his adventures until he joined the armed forces and later vanished.
