There are 2 mascots in Hiroshima Toyo Carp. One is "Carp Boya", and the other is "SLYLY". Carp boy is the first mascot of Japanese baseball team. With an intention to give dreams to children, a strapping boy was illustrated. Blue-green colored SLYLY, dressed in the Carp uniform, was designed by a character production company of Sesame Street. When the team scores many points, pink colored SLYLY suddenly appears to cheer up the ballpark.
