This blue cap hat has the theme of "Enerbeam" from Sonic Boom. It's an all-over print cap with a CG printed graphic of running Sonic on the front. He has speed lines behind him. The blue enerbeam from the game appears at the edges of the cap on both sides…
Back to the small stuff. You probably recognize the key chain from Sonic Keychains of Japan, but it is standing next to a walking wind up toy Sonic. Fun!
