A Sonic, Shadow and Knuckles basket ball. How unusual! These do not seem to be Sonic X specific, but still have rather cool art. They took good measure to make each ball different and special. These are standard size, though it's hard to tell in these photos. Still, they make a great collectible! Too bad no one knows where to find them...and anyone who sells them over ebay won't tell you.

There is some conflict as to whether these were all standard size, mini (5 inch) or they came in both sizes. The mini ones could be won at Bush Gardens in VA.
