In one of the arenas on Beach Spikers Volleybal, you can find this giant Sonic decoration. This was a Gamecube game. He appears in the background for the stage as a giant wind powered advertisement. These giant mascot shaped wind-powered things do get trotted out at sporting events, so that's a realistic addition. The shape is a 3D Sonic sprite at super large scale, holding a volleyball with the ad on it. You can see a SEGA sign to the right as well. This is a nice touch that not only adds Sonic, but realism too.
