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.
